Types of insect bites
Most people know the itchy small welts of a mosquito bite, but there are many other types of bugs—from bed bugs to ticks to black flies—that can take a nip out of us. And then there are bees and wasps with their painful stingers.
Most insect bites and stings can be itchy or painful, and sometimes red and swollen. But some bug bites can also cause more serious issues like an allergic reaction or, as in the case of ticks, they can sometimes transmit diseases.
If an insect bite is itchy, you can usually treat it with OTC medications, like an antihistamine and hydrocortisone creams, but some types of bites may need to be treated by a healthcare provider.
Symptoms of insect bites
The most common symptoms of insect bites and stings are minor itching, irritation, or pain by the bite. Several minutes after the bite or sting,you may notice swelling and redness. For most bites or stings, the swelling will be small and should only last several hours to a few days.
- Minor swelling
- Pain or tenderness
Less common symptoms
- An allergic reaction can cause a stronger skin reaction, like a large area of redness and swelling around the bite or sting.
- A large area of redness and skin that’s warm and painful to touch could be a sign of an infection called cellulitis.
- A severe allergic reaction, called anaphylaxis, may include trouble breathing, swelling of your mouth and throat, immediate rash, vomiting, and fainting.
How do I know what type of bug bite or sting I have?
Here’s how to tell what type of bug may have bitten you:
Mosquitoes usually cause small, red bumps and the itching starts right after you're bitten. You can often see a small dot where you were bitten. Young children may get more severe swelling.
Ticks can carry Lyme disease, which needs to be treated with antibiotics. Ticks attach to your skin, so the tick may actually still be there when you find the bite. Tick bites are often in warm places of the body like the groin, behind the knees, on the scalp, and in the armpits. If you see a red rash that looks like a bullseye, it may be a sign of early Lyme disease. It can take 1–2 weeks after being bitten for the rash to appear.
Mite bites are usually small, red, and itchy, and often are grouped together on a small area of the body. When mites infest your skin and lay eggs, it is known as scabies, Scabies can be very itchy and usually causes red lines on the skin. It is often inside the webs of fingers, wrists, armpits, and groin areas.
Bed bug bites
Bed bug bites look like multiple small red bumps, usually appearing in clusters or lines on your skin. They can be itchy and often have a small red dot in the middle of each bump.
Fly bites are usually painful and sharp when they occur. Common flies in the U.S. include black flies, horse flies, and deer flies. Occasionally bites can become itchy and cause allergic reactions.
Spider bites often look like a single isolated bump or fluid-filled sac. Some spiders, like brown recluse spiders, are more dangerous and can cause severe pain and burning, and a dark purple or blue spot with a red ring around it, or an open sore. A bite from a black widow spider can cause muscle pain and numbness around the bite or bodywide muscle pain and tremors. It also sometimes causes headache, nausea, and vomiting.
Bees can plunge their tiny stingers into your skin and release a bit of venom. It usually just causes pain and some redness around the sting for a few minutes that then goes away. But some people are allergic to bee stings and may have a serious reaction, like swelling and trouble breathing.
If you are bitten by an insect, in most cases you can treat it at home. However, if you have any trouble breathing or swelling of your mouth or throat, you should immediately go to the ER or call 911. If you know you are allergic and have an EpiPen, then use it right away.
If you have a rash or redness that continues for several days without getting better, you should see a healthcare provider.
