Take a second-generation (non-drowsy) antihistamine: cetirizine, fexofenadine, or levocetirizine.Apply an ice pack to the site for 10 minutes and again as needed.Wash the site with soap and water or wipe with an antibacterial.

Use window screens and/or air conditioning to keep windows closed.Wear clothing treated with permethrin (an insecticide).Cover your body when outside, especially when hiking.Wearing pants and long-sleeved shirts is not everyone's favorite thing to do during the summer, but shorts and short sleeves put you at higher risk of bites and stings. The best way to stop feeling itchy is to not get bitten. When you see a bite or feel itchiness, it is best to treat the bite, and do not scratch. An infection can last for days or longer and can be very serious without treatment.

Scratching creates greater risk for developing skin infections and abscesses that cause systemic symptoms: fever, chills, nausea, and vomiting. So, scratching causes the bite to become more and more itchy and the swelling to become larger and larger.Īlso, when you scratch, you're breaking down your skin. When you scratch an itchy bite you cause more inflammation and release more histamine-which is what caused the itch in the first place. Insects are also attracted to people who are pregnant (possibly because they exhale more carbon dioxide and have a higher body temperature), certain colors of clothing, and beer. We also know mosquitos are attracted to people who exhale more carbon dioxide, have a higher body temperature, and have a limited variety of bacteria on their skin. We do know there is a genetic component and that certain people secrete chemical signals that insects are more attracted to You may have heard that certain blood types are more appealing than others to insects, but the evidence is not there. Why do some people get bit more than other people? If you have reactions off-site-you were bit on the elbow, but your leg is swelling you have hives everywhere you are coughing, dizzy, nauseated, or vomiting you have diarrhea or trouble breathing or you fainted immediately or shortly after the bite or sting-it’s time to call 911. If the bite is getting worse after 24 hours, call your doctor and take photos to record the changes. It’s normal for a bite or sting to swell and itch, which can last up to 48 hours, getting slightly better over time. What’s a sign a bug bite is something more serious?Īs long as the reaction stays localized-around the bite-it's usually not serious. Examples include an allergic reaction or infection that can be life-threatening. If you have a systemic reaction-symptoms beyond the site of the bite-your body is mounting a bigger immune response. But most of the time, any local reaction to a bug bite says you're functioning normally. What does a bug bite say about your immune system?Įveryone thinks their immune system is off when they see something they have not experienced before: a larger bump, a redder lump, an itchier itch, a stingier sting. If you scratch a bite, it becomes more inflamed, causing more itch, and you increase the potential for infection. Your immune system fights substances in the bug saliva with a variety of mediators, such as histamine, which causes swelling, inflammation, and itchiness. When bugs bite, they inject saliva, triggering your body to react.

We asked Brooks to tell us everything we should know about bugs and their bites. Mosquitoes, ticks, and fleas cause the most bug bites-and carry diseases like West Nile and Lyme disease, which can be serious-so it’s worth trying to avoid bug bites as much as possible. Most bug bites do not cause problems and will resolve on their own, but that doesn’t mean you shouldn’t try to avoid them. “During the summer we provide insects more opportunity to bite,' says pediatric allergist and immunologist Joel Brooks, MPH, DO, “and the number of reported cases of disease from mosquito, tick, and flea bites has more than tripled in recent years according to the CDC.” Others can leave you or your child with bacterial infections, parasites, or viruses. Most bug bites (usually from mosquitoes) stop itching after a day or two. Itching, stinging, and swelling really take the fun out of being outdoors and opening windows in the summer.
