Understanding the Brown Recluse Spider and Its Venom

The brown recluse spider, despite its small size of about half an inch, packs a potent punch with its venom. While rarely fatal, its bite can cause significant skin damage, nausea, and muscle pain. The venom contains two key toxins:

• Sphingomyelinase D: Capable of destroying skin tissues
• Hyaluronidase: Accelerates venom penetration into tissue

These toxins can destroy blood vessels, tissue, and nerves, potentially leading to skin necrosis – the death of skin tissue. A 2020 study revealed that 40% of patients bitten by brown recluse spiders experienced hemolysis, the breakdown of red blood cells.

How toxic is brown recluse venom compared to other venomous creatures?

Surprisingly, the venom of a brown recluse spider is more toxic than that of a rattlesnake. However, the spider can only release a small amount into a human’s system, which is why fatalities are extremely rare. Nonetheless, prompt treatment is crucial to slow the venom’s effects and promote faster healing.

Identifying a Brown Recluse Spider Bite: Symptoms and Stages

Recognizing a brown recluse spider bite can be challenging, especially in its early stages. The bite itself is often painless due to the spider’s small fangs. Here’s a timeline of symptoms:

Initial Bite (0-8 hours)

In the first few hours after the bite, you may notice:

• A red, tender, and inflamed area
• Two tiny puncture holes
• A pale center with an inflamed reddish outer ring
• A burning sensation developing over several hours

Peak Pain (24 hours)

Pain typically reaches its height about 24 hours after the bite occurs.

3-5 Days Post-Bite

Depending on the amount of venom injected and your health, you may experience:

• Localized discomfort that subsides within a few days (for minimal venom injection)
• Wound expansion over several days to weeks (if venom spreads)
• Development of a blister or necrotic lesion
• Appearance of a dry, sinking patch of skin or a bluish patch
• Redness around the lesion with a pale center
• Formation of a central blister

1-2 Weeks Post-Bite

For more severe bites, the toxin continues to break down the skin if left untreated. You may observe:

• Development of necrotic (dead) tissue called eschar
• A large, black scab covering the wound area

3 Months Post-Bite

Most brown recluse bites heal fully within 3 months or less. However, in rare severe cases:

• Necrosis may extend beyond the skin into muscles
• Surgical evaluation may be necessary to remove or repair dead tissue

When to Seek Medical Attention for a Brown Recluse Spider Bite

While many brown recluse spider bites can be treated at home, certain symptoms warrant immediate medical attention. These include:

• Chills
• Dizziness
• Fever
• Rash
• Vomiting

These symptoms may indicate a severe reaction or anaphylactic shock, which is life-threatening. Individuals with compromised immune systems, children, and older adults are at higher risk for severe reactions.

Can a brown recluse spider bite be mistaken for other conditions?

Yes, if the wound doesn’t respond to treatment or symptoms don’t align with typical brown recluse bite presentation, your doctor may consider a differential diagnosis. This could include other insect bites or separate skin conditions.

Treatment Options for Brown Recluse Spider Bites

Treatment for a brown recluse spider bite varies depending on the severity of the bite and individual reactions. Here are some general treatment guidelines:

First Aid and Home Treatment

1. Clean the affected area thoroughly with soap and water
2. Apply a cold compress or ice pack to reduce pain and swelling
3. Elevate the affected area if possible
4. Take over-the-counter pain relievers as needed
5. Monitor the bite area for signs of infection or worsening symptoms

Professional Medical Treatment

For more severe bites or reactions, medical professionals may provide:

• Tetanus immunization if needed
• Antibiotics to prevent or treat secondary infections
• Stronger pain medications
• Antihistamines for allergic reactions
• Dapsone or other medications to reduce necrosis (in severe cases)
• Surgical debridement of necrotic tissue (in extreme cases)

Are there any specific antidotes for brown recluse spider venom?

Currently, there is no specific antidote for brown recluse spider venom. Treatment focuses on managing symptoms and preventing complications. Research is ongoing to develop more targeted treatments.

Preventing Brown Recluse Spider Bites

While brown recluse spiders are not aggressive, they may bite when threatened. To reduce your risk of encounters:

• Seal cracks and crevices in your home’s exterior
• Keep storage areas clean and clutter-free
• Shake out shoes and clothing before wearing, especially if stored in dark areas
• Wear gloves when handling firewood, rocks, or items stored in basements or attics
• Use caution when reaching into dark spaces or moving items that have been undisturbed for long periods

Where are brown recluse spiders commonly found?

Brown recluse spiders prefer dark, undisturbed areas. They’re often found in:

• Closets
• Attics
• Basements
• Garages
• Woodpiles
• Cardboard boxes

They’re most common in the central and southern United States, particularly in the Midwest and South Central regions.

Identifying the Brown Recluse Spider

Correctly identifying a brown recluse spider can help in prevention and prompt treatment if a bite occurs. Here are key features to look for:

• Size: Usually no larger than a half-inch in length, including legs
• Color: Plain tan or brown, with no stripes or patterns
• Distinctive mark: Dark, violin-shaped mark on the head (giving it the nicknames “violin spider” or “fiddleback spider”)
• Eyes: Six eyes arranged in three pairs in a horizontal row, unlike most spiders which have eight eyes
• Legs: Eight thin legs

How can you distinguish a brown recluse from other common house spiders?

The violin-shaped mark and six-eye arrangement are the most distinctive features of the brown recluse. Many other spiders have similar coloring but will typically have different markings or eight eyes. If you’re unsure, it’s best to consult an expert or treat any unknown spider with caution.

Long-Term Effects and Complications of Brown Recluse Spider Bites

While most brown recluse spider bites heal without long-term consequences, severe cases can lead to complications:

• Persistent pain or discomfort at the bite site
• Scarring, which may require cosmetic surgery in extreme cases
• Kidney damage (rare, but possible in severe systemic reactions)
• Psychological effects, such as anxiety or arachnophobia

Can brown recluse spider bites cause systemic effects?

Yes, in rare cases, brown recluse spider bites can cause systemic effects. These may include:

• Hemolytic anemia (destruction of red blood cells)
• Thrombocytopenia (low platelet count)
• Disseminated intravascular coagulation (blood clotting disorder)
• Acute renal failure (in extremely rare cases)

These systemic effects are more likely in children, older adults, or individuals with compromised immune systems. Prompt medical attention is crucial if any signs of systemic reaction occur.

Myths and Misconceptions About Brown Recluse Spiders

There are several common myths about brown recluse spiders that can lead to unnecessary fear or improper treatment. Let’s address some of these:

Myth 1: Brown recluse spiders are aggressive and commonly bite humans

Reality: Brown recluse spiders are actually shy and non-aggressive. They typically only bite when pressed against the skin, such as when trapped in clothing or bedding.

Myth 2: Brown recluse spiders are found all over the United States

Reality: Their range is primarily limited to the central and southern United States. Many reported sightings outside this range are often misidentifications.

Myth 3: All necrotic-looking wounds are caused by brown recluse bites

Reality: Many conditions can cause similar-looking wounds, including other insect bites, bacterial infections, and various skin disorders. A definitive diagnosis often requires expert evaluation.

Myth 4: You can easily identify a brown recluse bite by a bull’s-eye pattern

Reality: While some bites may develop a pale center surrounded by redness, this is not always the case. The appearance can vary significantly between individuals and over time.

What are some common misdiagnoses for brown recluse spider bites?

Several conditions are often mistaken for brown recluse spider bites, including:

• Methicillin-resistant Staphylococcus aureus (MRSA) infections
• Lyme disease
• Herpes simplex
• Diabetic ulcers
• Chemical burns
• Fungal infections
• Other arthropod bites or stings

This underscores the importance of seeking professional medical evaluation for any concerning skin lesions or suspected spider bites.

Research and Future Directions in Brown Recluse Spider Bite Treatment

While current treatments for brown recluse spider bites primarily focus on symptom management and preventing complications, ongoing research aims to develop more targeted therapies. Some areas of investigation include:

Antivenom Development

Researchers are working on developing an effective antivenom specifically for brown recluse spider bites. This could potentially neutralize the venom’s effects more quickly and effectively than current treatments.

Enzyme Inhibitors

Studies are exploring the use of enzyme inhibitors that could block the action of the venom’s destructive components, potentially reducing tissue damage and speeding healing.

Improved Diagnostic Tools

Developing more accurate and rapid diagnostic tests could help differentiate brown recluse bites from other conditions, leading to faster and more appropriate treatment.

What are some promising new treatments on the horizon for brown recluse spider bites?

While still in various stages of research, some promising approaches include:

• Targeted antibody therapies that could neutralize specific venom components
• Novel wound healing technologies to promote faster tissue regeneration
• Gene therapy approaches to counteract the venom’s effects at a cellular level
• Combination therapies that address both local and systemic effects of the venom

As research progresses, we may see more effective and specialized treatments for brown recluse spider bites in the future, potentially reducing healing time and minimizing complications.

How to Identify and Treat a Brown Recluse Spider Bite

A bite from a brown recluse spider can be mild or severe and may require medical attention. The toxins from this spider’s bite can cause tissue death.

Bites from the brown recluse spider almost never result in death but can cause serious skin damage, nausea, and muscle pain. With proper care, mild bites resolve within days to weeks, while more severe cases can take months to heal.

A bite from the brown recluse spider requires first aid, and if necessary, professional medical attention. Treatment often includes cleaning the affected skin, pain relievers, and icing.

Keep reading to learn the symptoms and stages of a brown recluse spider bite, how to identify the spider, and when to seek help.

What’s in the bite?

Even though this spider’s size maxes out at about a half-inch, its venom is more toxic than that of a rattlesnake. Luckily, the brown recluse is only capable of releasing a little into our system.

Here are two key toxins in the venom:

• Sphingomyelinase D has the potential to destroy skin tissues.
• Hyaluronidase can speed the venom’s penetration into tissue.

Was this helpful?

A brown recluse’s venom can destroy blood vessels, tissue, and nerves. As a result, the skin tissue can die, a phenomenon called skin necrosis.

In a 2020 study of 97 patients bitten by the spider, 40 percent experienced hemolysis, the damaging or breaking down of red blood cells.

Prompt treatment can slow these effects and allow your skin to begin healing faster.

Initial bite

Brown recluses have very small fangs, and their bite is usually painless. Unless you saw it happen, at first, you might not even be aware that a spider has bitten you.

You may start to notice a red, tender, and inflamed area about 2 to 8 hours after the spider bit you. Over the course of the next several hours, the irritation may cause a burning sensation.

The bite may appear as two tiny puncture holes. Early on, its center will be a pale color, with an inflamed reddish outer ring. The pain usually reaches its height at about the 24-hour mark after you are bitten.

After 3 to 5 days

In some people, the brown recluse’s venom is localized to only the area where the spider bit you. If the spider injected minimal venom and you’re healthy, the discomfort usually goes away in a few days.

But for others, the venom spreads. This causes the wound to expand, usually over a period of several days to weeks. Some people will develop a blister, and then a “necrotic lesion” due to the spider’s bite. This means the bite causes an ulcer or open sore, and tissue begins to die.

This may look like the following:

• dry, sinking patch of skin
• bluish-appearing patch of skin
• redness around the lesion with a pale center
• central blister

After 1 to 2 weeks

For mild bites, you should be mostly healed by 3 weeks or see a drastic reduction in inflammation.

But if you have a more severe bite, the spider’s toxin will continue to break down the skin, especially if untreated. The site of the wound may start to develop necrotic (dead) tissue called eschar. This looks like a big, black scab covering the wound area.

3 months later

Most brown recluse bites will heal fully, without complications, in 3 months or less.

In very rare cases where a lot of venom was delivered, necrosis in the wound can extend beyond the skin and into the muscles. If tissue death continues to occur or has already affected a large area, you’ll need to be evaluated by a surgeon. Surgery may be required to remove or repair excess dead tissue.

If the wound hasn’t responded to treatment or symptoms don’t align with the typical presentation of a brown recluse bite, it may be time for a differential diagnosis. Your doctor will consider other potential culprits of your symptoms, like another type of insect bite or a separate skin condition.

Severe reactions to a brown recluse spider bite

Some people have severe or life threatening reactions to brown recluse bites. These responses to the bite are more likely in those with compromised immune systems, including children and older adults.

Severe reactions to a brown recluse bite can include the following symptoms:

• chills
• dizziness
• fever
• rash
• vomiting

If you or a loved one is experiencing the above symptoms, seek emergency medical assistance. This may be a sign of anaphylactic shock, a life threatening allergic reaction.

The brown recluse spider is usually no larger than a half-inch in length, including its eight thin legs. It’s a plain tan or brown color, with no stripes or patterning. Adults almost always have a dark, “violin-shaped” mark on their heads. For this reason, the brown recluse is sometimes called the “violin spider” or “fiddleback spider.”

Brown recluses have six eyes instead of the usual eight. These eyes are arranged in a horizontal row of 3 pairs on the face.

If you see a brown recluse or signs of them, like when they “shed” their skins, collect evidence (if safe to do so). If you have a picture of the spider, this could help a doctor determine if a brown recluse bit you, and if you need medical treatment.

If bitten, it’s important to:

• avoid touching or scratching the bite
• clean the affected area with soap and water
• apply a fresh, non-stick bandage

Do not attempt to extract the spider’s venom. While first-aid procedures for several types of bites and stings involve trying to extract poison or venom, the Centers for Disease Control and Prevention (CDC) advises never to do this for a brown recluse bite. Attempting to squeeze or pierce the skin around the bite can spread the toxin and irritate the wound.

Not all bites require medical treatment, and some can be treated at home. Keep close tabs on the bite. If it causes acute burning and pain or is getting worse instead of better after a few days, see a doctor right away.

Doctors will often use the RICE method (rest, ice, compression, and elevation) to treat a suspected or confirmed brown recluse bite.

In addition to the first aid steps of cleaning and dressing the wound, here are some key steps:

• applying cloth-covered ice packs for 10 minutes at a time to keep the spider’s venom from spreading
• elevating the affected area and refraining from touching it
• taking an over-the-counter nonsteroidal anti-inflammatory drug (NSAID) or a stronger prescription
• receiving a tetanus shot if yours isn’t up to date

Depending on the severity of your symptoms, further treatments may be used.

These include:

• antibiotics to treat a confirmed or suspected infection
• special wound dressings or ointments to promote healing and reduce pain
• rarely, skin grafts or wound debridement to repair larger areas of damaged skin

Seeking treatment as soon as possible can help reduce the need for more invasive treatments.

Brown recluse spider bites can be hard to diagnose.

The bite can resemble a lot of other medical conditions, including:

• staph infection
• pressure ulcers
• wounds due to diabetes
• other spider or insect bites
• an allergic skin reaction to something else

Geographical location is an important consideration when considering a potential brown recluse bite. If you don’t live or haven’t traveled to a place where brown recluse spiders live (the south-central United States), then your bite is probably due to something else.

The “NOT RECLUSE” diagnostic criteria

Some doctors may use the mnemonic NOT RECLUSE to determine if the bite could or couldn’t be from a brown recluse. This can help you (and them) remember the criteria for which the spider’s bite is judged.

The bite usually isn’t from a brown recluse if it has the following characteristics:

• Numerous. A brown recluse usually only bites once — not multiple times.
• Occurrence. Brown recluses aren’t aggressive. Unless you’ve been in a place where they tend to hide or live, it’s not likely one bit you.
• Timing. Brown recluses only bite in months when they’re active — usually from April to October.
• Red center. Brown recluse bites usually have a pale center with redness around the bite area.
• Elevated. Brown recluse bites are usually flat — if the area is elevated, it’s not likely a brown recluse bite.
• Chronic. A bite from a brown recluse will usually heal within 3 months.
• Large. A brown recluse bite is rarely larger than about 5 inches across. If the bite is larger, it could be from something else.
• Ulcerates too early. Most brown recluse spider bites won’t ulcerate until 1 to 2 weeks after the bite occurs.
• Swollen. Brown recluse spider bites don’t usually cause significant swelling unless they’re on the face or feet.
• Exudative. Brown recluse bites don’t usually leak or cause exudate (pus). They’re more blistering or scab-like in nature.

“Recluse” is an appropriate term for describing these shy spiders, which avoid light and hide in dark crevices. Brown recluse spiders aren’t aggressive by nature and will only bite if feeling threatened or trapped.

We don’t advise poking around for them — it’s best to leave this to a professional.

Ways you can try to avoid brown recluse bites include:

• Reduce clutter in your home wherever possible. This includes no piles of newspapers or old cardboard boxes.
• Keep shoes and clothes off the floor. Shake out your shoes before wearing to ensure spiders aren’t in them.
• Store items in air-tight plastic containers. This stops spiders from getting into them.
• Wear long sleeves and gloves while sorting through old materials. This includes boxes in an attic. Spiders can’t usually bite through clothing, so this can offer some protection.
• Ensure cracks and holes in your home’s foundation and structure are properly sealed. Spiders can enter through these areas.
• Place flat glue traps in areas where spiders may live in your home. Examples include along baseboards where the wall and floor meet, as well as around areas of clutter.

Professional exterminators can also help you get rid of these and other pests that may cause bites and stings.

Regions found	These spiders typically live in the south-central portion of the United States, including Texas, Iowa, Oklahoma, Tennessee, and Georgia. It’s rare but possible that the spider gets accidentally transported outside its region.
When they appear	Brown recluses go into “harborages” for the winter, which is any hidden area the spider can find shelter in. They emerge between April and May, usually going away around October.
Where they live	These spiders look for warm crevices to crawl under, like insulation, cardboard boxes, or between pages of newspapers. Outdoors, they often live under the bark of dead trees or under rocks. They may crawl into shoes or bedding and bite you when they accidentally become wedged against your skin.
What they eat	Brown recluses do spin webs, but they don’t use them to trap their prey. Instead, the web is used as a home or refuge. They eat crawling bugs, like cockroaches, ants, and crickets.
Lifespan	Brown recluses live long lives, sometimes up to 5 to 7 years. They can go for extremely long periods without eating.

Because of their size and brown-ish appearance, the wolf spider is often mistaken for the brown recluse.

But the wolf spider is not venomous to humans. They can still bite, which leaves a small red bump that usually goes away in a few days. You’ll need to clean and treat the bite, so it doesn’t become infected and watch out for signs of an allergic reaction.

Here’s a breakdown of major differences between these two arachnids:

Brown recluse spider bites are often painful and can cause skin tissue to die (skin necrosis). It may take several hours to notice that you’ve been bitten.

Implementing first aid can help reduce symptoms. Clean the skin with soap and water, and use a non-stick bandage. Icing and elevation can help prevent the toxin from spreading. OTC pain medications can help with discomfort.

Avoid itching the bite and do not attempt to extract venom.

With proper care at home, most brown recluse bites will heal on their own over the course of several weeks. If your bite is especially painful or skin inflammation is spreading, see your doctor for evaluation and further treatment.

  	Attitude towards humans :	bites but is not poisonous Are you afraid of spiders? TerribleNo The family of hermits is one of the small but dangerous ones. There are only 100 species of the genus and they are distributed in the Old and New Worlds, in its warm regions. One of the most poisonous representatives is the brown recluse spider. They fully justify their name both in color and in lifestyle. The spider is nocturnal, preferring to live in dark places. The hue can vary from dark yellow to red-brown. The size of adults is from 8 to 12 cm, both sexes are almost the same. Life cycle The life span of the brown recluse spider in nature is up to 4 years. Females and males meet only once for mating. The female then lays eggs throughout her life. Every summer the female lays eggs in a white bag. Each contains up to 50 eggs. They appear soon and molt 5-8 times until full maturity. Food and habitat Nocturnal recluse spiders prepare their non-sticky webs in semi-dark places. He, in view of the development by people of a large part of the steppes and forest-steppes, becomes an undesirable neighbor. The spider lives: under the branches; in cracks in the bark; under stones; in sheds; in attics; in cellars. In rare but possible cases, spiders crawl into bed or clothes. In such a situation, they bite. The brown recluse eats all the insects it finds in its webs. Danger of brown recluse spider The animal prefers not to touch people and does not look for trouble itself. A bite is possible, but only if a person drives the spider into a trap. Not everyone develops an allergic reaction to a bite, much less necrosis. The consequences depend on the amount of injected poison and the condition of the person. The bite of the recluse spider is not very painful, and therefore dangerous. People do not immediately seek medical help. Here’s what to look out for: The bite is like a pin prick. The limbs are most commonly affected. Brown recluse spider. Itching, pain and discomfort appear within 5 hours. Then nausea is felt, severe sweating begins. A severe bite causes a white spot at the site. Over time, it dries up, blue-gray spots appear, the edges are uneven. With severe damage, open wounds appear, necrosis occurs. If the spider has already bitten If possible, the culprit of the wound should be caught. The bite site is washed with soap, ice is applied so that the poison does not spread. If the symptoms alternately appear, then you should seek medical help. How to avoid the brown recluse People who live in areas where they are in danger should be careful. Check items stored in cabinets. Seal up ventilation slots and gaps to minimize the risk of spiders. Clean up in a timely manner so that food sources for spiders do not settle in the dwelling. In the yard, clean all places where the spider can live – garbage containers, timber. If the spider does not pose a direct threat, it is better to bypass it. He doesn’t attack himself. Conclusion The brown recluse is one of the most dangerous arachnids. It has a strong venom that can cause necrosis. But they only bite in a desperate situation, when they are cornered. And the fact that they are real hermits only plays into the hands of people. If they live in nature, by chance meeting, there is absolutely no risk.

A bite from a brown recluse requires first aid and, if necessary, professional medical attention. Treatment often includes cleaning the affected skin, pain medication, and icing. Continue reading to learn about the symptoms and stages of a brown recluse spider bite, how to identify the spider, and when to seek help. What’s in the bite? Although the maximum size of this spider is about half an inch, its venom is more toxic than that of the rattlesnake. Fortunately, the brown recluse is only able to release a small amount into our system. Here are the two key toxins in the venom: Sphingomyelinase D has the potential to destroy skin tissues. Hyaluronidase may accelerate the penetration of the poison into tissues. Brown recluse bite photo Brown recluse bite symptoms and stages Brown recluse venom can destroy blood vessels, tissues and nerves. As a result, skin tissue can die, a phenomenon called skin necrosis. In a 2020 study of 97 patients bitten by a spider, 40 percent experienced hemolysis, damage or destruction of red blood cells. Early treatment can slow down these effects and allow your skin to start healing faster. Initial bite Brown recluses have very small fangs and their bite is usually painless. If you didn’t see it happening at first, you may not even know you’ve been bitten by a spider. You may start to notice a red, sore, and inflamed area about 2 to 8 hours after a spider bite. Over the next few hours, irritation may cause a burning sensation. The bite may look like two tiny holes. Initially, its center will be pale in color with an inflamed reddish outer ring. The pain usually peaks about 24 hours after the bite. After 3-5 days In some people, brown recluse venom is localized only in the place where the spider bit you. If the spider has injected a minimal amount of venom and you are healthy, the discomfort usually goes away after a few days. But for others the poison spreads. This causes the wound to expand, usually over a period of several days to weeks. In some people, a blister and then a “necrotic lesion” develops due to a spider bite. This means that the bite causes an ulcer or open wound and the tissue begins to die. It may look like this: dry, sinking area of ​​skin bluish area of ​​skin redness around the lesion with a pale center central blister 1-2 weeks later For minor bites, you should mostly heal by 3 weeks or see a dramatic reduction in inflammation. But if you have a stronger bite, the spider toxin will continue to break down the skin, especially if left untreated. At the site of the wound, necrotic (dead) tissue, called a scab, may begin to develop. It looks like a large black scab covering the area of ​​the wound. 3 months later Most brown recluse bites heal completely without complications in 3 months or less. In very rare cases where a lot of venom has been delivered, necrosis in the wound may extend beyond the skin and into the muscles. If tissue death continues or has already affected a large area, you need to be examined by a surgeon. Surgery may be required to remove or repair excess dead tissue. If the wound does not heal, or if the symptoms do not match the typical brown recluse bite, it may be time for a differential diagnosis. Your doctor will consider other potential culprits for your symptoms, such as a different type of insect bite or a separate skin condition. Severe reactions to brown recluse stings Some people have severe or life-threatening reactions to brown recluse stings. These bite reactions are more likely in people with weakened immune systems, including children and the elderly. Serious reactions to a brown recluse sting may include the following symptoms: chills dizziness fever rash vomiting 9001 3 If you or a loved one experience any of the above symptoms, seek emergency medical attention. This may be a sign of anaphylactic shock, a life-threatening allergic reaction. What does a brown recluse look like? The brown recluse usually does not exceed half an inch in length, including its eight thin legs. It is plain tan or brown in color, with no stripes or patterns. Adults almost always have a dark, violin-shaped marking on their head. For this reason, the brown recluse is sometimes referred to as the “violin spider” or “violin spider”. Brown hermits have six eyes instead of the usual eight. These eyes are arranged in a horizontal row of 3 pairs on the face. What to do if you suspect you have been bitten by a brown recluse If you see brown recluses or signs of them, such as when they shed their skin, collect evidence (if safe to do so). Having a photo of a spider can help your doctor determine if you have been bitten by a brown recluse and if you need medical attention. In case of a bite important: do not touch or scratch the bite clean the affected area with soap and water apply a fresh non-stick dressing Do not try to extract the spider’s venom. While first aid procedures for several types of bites and burns involve trying to extract the venom or venom, the Centers for Disease Control and Prevention (CDC) advises never doing this for a brown recluse bite. Attempting to squeeze or puncture the skin around the bite can spread the toxin and irritate the wound. Not all bites require medical treatment, some can be treated at home. Pay close attention to the bite. If it causes severe burning and pain, or gets worse instead of better after a few days, see your doctor right away. Brown recluse bite treatment Physicians often use RICE (Rest, Ice, Compression and Elevation) to treat a suspected or confirmed brown recluse bite. In addition to the first aid steps of cleaning and dressing the wound, here are a few key steps: ice packs covered with cloth lifting the affected area and refraining from touching it taking an over-the-counter non-steroidal anti-inflammatory drug (NSAID) or stronger prescription getting a tetanus shot if you do not have an up-to-date 9 0013 B Depending on the severity of your symptoms, additional treatments may be used. These include: antibiotics for the treatment of confirmed or suspected infection special wound dressings or ointments to promote healing and relieve pain rarely skin grafts or debridement to repair large areas of damaged skin. Seeking treatment as soon as possible can help reduce the need for more invasive treatments. How a doctor diagnoses a brown recluse bite Brown recluse bites are difficult to diagnose. The bite can resemble many other diseases, including: staph infection bedsores wounds due to diabetes bites from other spiders or insects allergic skin reaction to something else Geographic location is an important consideration when considering a potential brown recluse bite. If you do not live or have traveled to areas where brown recluse spiders live (south and central US), then your bite is probably caused by something else. Criteria for diagnosing “NOT HERMIT” Some clinicians may use the NOT RECLUSE mnemonic to determine if a bite could be a brown recluse bite. This can help you (and them) remember the criteria by which a spider bite is judged. A bite is usually not from a brown recluse if it has the following characteristics: Numerous. The brown recluse usually bites once, not multiple times. Entry. Brown hermits are not aggressive. If you haven’t been to a place where they tend to hide or live, it’s unlikely to bite you. Timing. Brown recluses only bite during the months they are active – usually from April to October. Red centre. Brown recluse bites usually have a pale center with redness around the bite area. Increased. Brown recluse bites are usually flat – if the area is raised, it is unlikely to be a brown recluse bite. Chronic. Brown recluse sting usually heals within 3 months. Large. The bite of the brown recluse is rarely more than 5 inches across. If the bite is larger, it could be from something else. Ulcers too early. Most brown recluse spider bites do not ulcerate within 1-2 weeks of being bitten. Swollen. Brown recluse spider bites usually do not cause significant swelling unless they are on the face or legs. Exudative. Brown recluse bites usually do not leak or cause exudate (pus). They are more like blisters or scabs in nature. How to avoid being bitten by a brown recluse “Recluse” is a good term to describe these shy spiders that avoid light and hide in dark crevices. Brown recluse spiders are not naturally aggressive and will only bite if they feel threatened or trapped. We do not recommend tinkering with them – it is better to entrust this to a professional. Ways you can try to avoid brown recluse bites include: Reduce clutter in your home wherever possible. This does not include stacks of newspapers or old cardboard boxes. Keep shoes and clothes off the floor. Shake shoes before putting them on to make sure there are no spiders in them. Store items in sealed plastic containers. This prevents spiders from getting into them. Wear long sleeves and gloves when sorting old materials. Including boxes in the attic. Spiders are usually unable to bite through clothing, so this may provide some protection. Ensure that cracks and holes in your home’s foundation and structure are properly sealed. Spiders can enter through these places. Place flat glue traps in areas where spiders can live in your home. Examples include along baseboards where wall and floor meet, and around areas of clutter. Professional exterminators can also help you get rid of these and other pests that can cause stings and stings. Brown Recluse Spider Quick Facts Want to learn more about the brown recluse spider’s traits? We have you covered. Regions Found These spiders typically live in the south-central United States, including Texas, Iowa, Oklahoma, Tennessee, and Georgia. Rarely, but it is possible that a spider accidentally enters outside its region. When they appear Brown recluses go to “hideout” for the winter, that is, to any hidden place where a spider can find shelter. They appear between April and May and usually leave around October. Where they live These spiders look for warm crevices to crawl under, such as insulation, cardboard boxes or newspaper pages. Outdoors, they often live under the bark of dead trees or under rocks. They can crawl into shoes or bedding and bite you if they accidentally nestle against your skin. What they eat Brown hermits weave webs, but do not catch their prey with them. Instead, the net is used as a home or refuge. They eat crawling bugs such as cockroaches, ants and crickets. Lifespan Brown hermits live a long time, sometimes up to 5-7 years. They can go without food for a very long time. Brown recluse bite vs wolf spider bite Because of its size and brown color, the wolf spider is often mistaken for the brown recluse. But the wolf spider is not poisonous to humans. They can still bite, leaving a small red bump that usually goes away after a few days. You will need to clean and treat the bite to keep it from becoming infected and watch for signs of an allergic reaction. Here is a breakdown of the main differences between these two arachnids: Brown Recluse Wolf Spider Size 1/4-1/2″ Size 1/2-2″ Poison bite, considered very dangerous nym for a person.
