Bug bites on foot: How to Know When It’s a Chigger Bite

How to Know When It’s a Chigger Bite

Sometimes called “berry bugs” or “red bugs,” chiggers populate large sections of the United States — including all of the South, the Great Plains, and the Mid-Atlantic. Though they’re often bright red in color, chiggers are only about the size of a grain of salt — making them almost impossible to spot either in the wild or on a person’s skin.

“Chiggers are a type of immature mite that spend time feeding on small mammals, and also on humans,” says Lee Townsend, PhD, a professor emeritus of entomology at the University of Kentucky in Lexington. Dr. Townsend says that there are many different species of mites, but only a few types that bite during their larval stage. It’s these that are referred to as chiggers. “Not all mites are chiggers, but all chiggers are mites,” he adds.

Unlike mosquitoes, ticks, and other biting bugs, chiggers don’t attach themselves to mammals in order to suck blood. Instead, chiggers feast on skin cells and tissue, Townsend explains. But much like mosquitoes and ticks, chiggers can induce a nasty skin reaction. That reaction, he says, comes from the chigger’s saliva, which they use to break down and digest the cells and tissues they devour.

Chigger Bites Look a Lot Like Other Bug Bites, So Here’s How to Correctly ID Them

As with all bug bites, there’s some person-to-person variation when it comes to chigger bites.

“Different people react differently to bites, so it can be really difficult to tell the difference between bites of things like mosquitoes from chiggers,” Townsend says. Especially if you’re bitten by a lone chigger, the red welt that forms may look more or less identical to a mosquito bite.

But there are bite characteristics that can show up that can help differentiate chiggers from other bugs. For one thing, chigger bites tend to take itchiness to a whole new level. “I don’t know of many things as intensely itchy as a chigger bite,” says Michael Merchant, PhD, a professor of entomology at Texas A&M University in Dallas.

Also, chiggers tend to latch onto a person’s skin in groups. You won’t be able to see them without the aid of a magnifying glass. But you may feel some irritation when they first start feeding. And the resulting bites often appear as clusters of red welts — as opposed to a single itchy lump or a red rash. (1) If you have a swath of itchy skin lumps that looks like many mosquito bites or welts, it’s a good bet you’re dealing with chiggers. (2)

Another characteristic of these bites: chiggers like to gather in areas that are hot and sweaty — like the insides of socks, at waistlines, inside armpits, or behind the knees, Dr. Merchant says. “If you see a pattern of bites only where your sock was, that’s probably chiggers,” he adds.

What Can I Do to Treat Chigger Bites and Relieve the Itching?

While itchy and uncomfortable — not to mention unsightly — chigger bites tend to resolve on their own within a week — and often within a few days. (3) “Once they’re done feeding, [chiggers] drop off on their own,” Townsend says. He recommends taking a hot shower and soaping the area thoroughly. (This can remove chiggers before they’ve had the chance to cause welts and irritation, he says.) Applying topical calamine cream can also help reduce the itch, he adds. So can cold compresses, oral antihistamines like diphenhydramine (Benadryl) or cetirizine (Zyrtec), and rubbing alcohol. (4)

Do you need to see a doctor? In most cases, no. “Chiggers can transmit diseases in some other parts of the world, but not here,” Townsend says of domestic chiggers.

That said, chigger bites can put a person at risk for a secondary infection. That could happen if you scratch the bite (or bites) and break open the skin, allowing in bacteria, Merchant says.

If the swelling or redness around a bite is getting worse several days after it first appeared, or if you notice a fever or other flu-like symptoms, those may be signs of an infection. The same is true if the bite is leaking fluid, has developed a yellow, golden crust, or has become painful, or if you’re experiencing hives, vomiting, or nausea — see a doctor. (5)

Doctors can prescribe prescription topical steroids or even inject dilute steroids into intensely itchy bites if you don’t experience relief from over-the-counter options.

Yes, You Can Avoid Getting Chigger Bites and Still Enjoy the Outdoors

Chiggers usually live in shaded or overgrown areas like forests and wild fields, Townsend says. “They need shelter from the sun and they like high humidity, so they tend to like tall grasses and places where there are mice and small mammals around,” he says. “You’re not going to run into many of them out in mowed or landscaped areas.”

For that reason, keeping yards or outdoor areas well-tended and free of overgrowth and brush are effective ways to keep chigger populations to a minimum. Staying on walking paths — as opposed to making your way through tall grass or wilder areas — is another way to avoid picking up chiggers. (6)

If you’re going to be tramping through woods or picking fruit in a field, those are times when you’ll want to take extra precautions to guard yourself against chiggers. Townsend recommends wearing long pants and tucking them into your socks. “Repellents also help,” he says, mentioning common types like DEET, which is also used to repel mosquitoes and ticks. Be sure to use those repellents on your shoes and lower legs — places chiggers tend to latch on.

And again, taking a hot, soapy shower after you’ve been in chigger-infested areas can help remove them before they cause skin irritation, Townsend says.

Chiggers are a nuisance — and their bites can be incredibly itchy. But if you can resist scratching those bites, they don’t cause any long-term issues or health complications.

Tips for How to Avoid Getting Mosquito Bites in the First Place

To minimize your bite risk, try to stay indoors at dawn and dusk — times when humidity often peaks. “The higher the humidity, the better for mosquitoes, so dawn and dusk are times when they tend to be active,” Day says.

He explains that mosquitoes are fragile insects, and their bodies dry out quickly if they’re exposed to arid conditions or extended stretches of bright sunlight (which is another reason they prefer hunting at dawn and dusk, as opposed to midday). They’re also weak fliers, he says, so any kind of breeze or fan-generated wind tends to keep them at bay. If you can find a place that’s exposed to wind, or you have a strong fan handy, both can prevent mosquitoes from biting you.

Long pants and shirtsleeves — especially tightly woven synthetic fabrics such as the types used in so-called athleisure garments — tend to keep mosquitoes off your skin. Repellents also work well, Day says. The CDC suggests looking for products that contain DEET, picaridin, IR3535, and oil of lemon eucalyptus, or p-menthane-3,8-diol (PMD). (6)  Apply these products to your ankles, wrists, forehead, elbows, and all the other knobby, bony places where the blood is up near the surface of the skin. Mosquitoes love to feast at these sites.

Also good to keep in mind: Mosquitoes are attracted to both the carbon dioxide humans exhale and the natural odors our bodies produce — stuff like sweat and foot odor. If you’ve been exercising, you’re likely to be both sweaty and producing higher amounts of carbon dioxide. Better to cool off and shower up indoors before heading outside. (7)

Follow all these precautions, and you can largely dodge mosquito bites all summer long.

Insect bite prevention

No summer is complete without insect bites. This is not only unpleasant, but sometimes dangerous to health.

The immune system of each person reacts to bites in different ways: from swelling, itching and pain to anaphylaxis. An anaphylactic reaction can develop after a bite from any insect. Fortunately, this is rare, but people who have experienced any kind of allergic reaction before should be especially vigilant.

An anaphylactic reaction occurs at lightning speed. A person feels weak, then symptoms quickly increase: difficulty breathing, increased heart rate, loss of consciousness.

If an anaphylactic reaction occurs, emergency medical attention is needed, as this condition is life-threatening.

A milder allergic reaction to insect bites manifests itself in the form of itching, inflammation of the bite site. When there are many such bites, it causes great discomfort. Often there are complications – the addition of a secondary infection.

5 common insect bites in summer

Mosquito bites are accompanied by severe unbearable itching – this is a reaction to the proteins contained in the saliva of the insect.

In some tropical countries, mosquito bites can transmit diseases such as malaria, Zika fever, Dengue fever, yellow fever.

Wasps, bees and hornets have stingers for self-defense. The sting contains a poisonous substance that enters the bite site, causing severe pain and burning. At the site of the bite, swelling, inflammation, redness and itching may appear. The most dangerous complication of such bites is anaphylaxis. The stings of bees, wasps, bumblebees and hornets are very dangerous for children.

Horseflies attack in hot stuffy weather. Their bite is quite painful, it can cause a sharp burning sensation. Often there is a feeling of itching, inflammation and swelling in the bite area. There may even be a bruise.

There are about 4,000 species of biting midges . The smallest of the flies that attack humans can range in size from 1 to 3 mm. Despite their tiny size, midge bites can be irritating and even cause local pain.

Flea bites leave small sores on the skin, usually several, next to each other, often on the ankles and legs.

First Aid

  • apply cold
  • remove tip
  • clean with antiseptic solution
  • do not scratch
  • if necessary, drink an antihistamine (recommended by a doctor, observing the age dosage)

Seek medical attention immediately, if you have had a severe allergic reaction to an insect sting in the past, or if you experience one or more of the following symptoms:

  • sudden urticaria
  • swelling of the face
  • labored breathing
  • dizziness
  • fainting

Basic precautions for preventing insect bites

Remain calm and walk away slowly if there are wasps, hornets or bees nearby – do not wave your arms and do not try to drive them away.

Wear closed clothing, do not walk barefoot on the grass.

Apply insect repellant to exposed skin or clothing as directed – repellants containing 50% DEET (diethyltoluamide) are most effective.

Avoid using strong perfumes, they can attract insects.

Be careful of flowering plants, trash, standing water, and open areas where food is served.

Avoid camping near bodies of water, do not keep containers filled with water in summer cottages – mosquitoes and horseflies are usually found near water.

In the evening, do not open the windows wide open if they are not equipped with a mosquito net.

It is also recommended that you take extra precautions if you are traveling to a part of the world where there is a risk of serious insect-borne diseases.

Let insects distract you from summer joys as little as possible this year!

Mosquitoes, midges (a substance that prevents blood from clotting). Therefore, the bite site is very itchy.

At the site of a mosquito bite, redness and a small itchy blister appear, the bite itself is not painful. But the bite of the midge is generally not immediately felt. Itching, burning appear the next day, and they are much stronger than with a mosquito bite, plus the midge bite site is very red and swollen.

What to do: To relieve itching, apply something cold (ice). You can also make a compress with a solution of soda (half a teaspoon per glass of water). The bite can be lubricated with an antihistamine cream (gel, ointment) or a special Balm after bites .

Important: care must be taken that the child does not comb the bites, otherwise the wound may become infected. The bite of the midge heals for a long time.

Horsefly

Horsefly is a large fly that loves damp places and sun. The bite of this insect is very painful.

A large blister immediately appears at the site of the bite of , which is very itchy.

What to do: Wash the bite with soap and water or treat with an antiseptic. To relieve itching and swelling, you need to apply cold, the same soda compress, antihistamine cream (gel, ointment) will help.

Important: horseflies are completely harmless in the shade and attack only on sunny lawns, closer to water bodies. If the bite is combed, then it will heal for a long time.

Bees, wasps, bumblebees

Bees, wasps, bumblebees, hornets (huge wasps) – these insects do not just bite, they sting and with the help of a sting introduce a strong protein poison into the human body. When bitten, bees leave a sting in the wound, so they bite once, but the rest of the stingers can attack again.

Burning pain, redness, swelling and itching of the skin appear at the site of the bite , the area around the wound becomes hot, if a bee has bitten, then a sting is visible. Sometimes, due to poison, intoxication or severe allergies can occur: the child has a headache, he is weak and lethargic, he is sick or even vomits, he has impaired coordination, his body temperature rises, rarely, but there is also loss of consciousness. The same reaction happens if several insects have stung at once.

What to do: remove the sting if there is one (better to do this with tweezers). Wash the wound with soap or treat with hydrogen peroxide. Apply cold. You can lubricate the sore spot with antihistamine cream (ointment, gel) . If the skin develops swelling and severe redness, give the child an antihistamine by mouth. After a bite, you need to watch the baby for about half an hour. In case of complications, a doctor should be called.

Important: if there are several bites, if they are in the mouth, face, neck, then it is better to go to the hospital or call a doctor: swelling spreads very strongly in these places.

Tick

Tick digs into the skin and secretes a large amount of saliva into the wound, along with it pathogens of various infections can enter the human body, the most common: encephalitis and borreliosis (Lyme disease). By itself, the tick bite is not felt in any way

A black dot of various sizes is visible at the site of the bite – this is the tick itself. There is no swelling or itching.

What to do : remove the tick. It is better to do this in an emergency room or hospital, because if there is no skill, then it is easy to tear off the body of the tick, and its head and proboscis will remain in the skin. But if the doctors are far away, then you can try to unscrew the insect with tweezers, like a screw (you can’t pull, just twist it). It is useless to drip oil on a tick and wait for it to fall off on its own. It is advisable to take the removed tick for analysis to find out if it is a carrier of the infection.

Repellents

  • These substances protect against bites, but it must be understood that poisons that are dangerous for insects are also dangerous for humans. It is necessary to use repellent only if there are really a lot of insects or their bite causes a strong reaction in the child.
  • It is necessary to apply only a baby product with a low concentration of the active substance (up to 10%). The repellent must not contain diethyltoluamide ( DEET ). It is toxic, so in children under 6 years old it is not even used for clothing.
  • Do not aerosolize the face – only cream, ointment or gel. Do not treat areas with scratches, wounds, inflammation, lips and eyelids with repellent. It makes no sense to treat skin areas hidden by clothing.
  • After the walk, change clothes, take a shower and wash off the remains of the substance from the child.
  • If there is an allergy, then it is better not to use the repellent at all.

How to prevent a bite

Preventing an insect bite is easier than treating it later:

  • Cover sweet fruits and desserts, otherwise they will attract a lot of insects. Before you give your child juice from a cup or a piece of watermelon, you need to see if a wasp or a bee is hiding there. And after eating, it is worth wiping the baby’s lips with a wet napkin.
  • Bright and colorful dresses strongly attract insects. They also love floral scents. So in nature it is better to dress discreetly and not eat sweet food.
  • It is better for a child not to walk barefoot on grass or sand – there may be a bee or a wasp sitting there.
  • When walking in a forest or a meadow (a place that is very fond of ticks), you need to wear clothes with closed sleeves, trousers with cuffs at the bottom (or tuck them into shoes). Put on a cap or panama on your head. Every hour it is worth carefully examining the clothes and body of the child.

Insects like to bite especially children, because their skin is thin, and blood circulation is very active.

A child can get a wasp or bee sting by inadvertently stepping on an insect with a bare foot, or if the child eats some sweet fruit that the insect has suddenly landed on.

All bloodsuckers look for prey, primarily by body temperature. To “hot” people they fly up faster.
