Why Do Bug Bites Itch

Here's a vexing question asked at picnics and beach parties everywhere Why do bug bites itch And the answer is They don't. Bug bites don't itch at all, sometimes you don't even feel them, and that's pretty amazing because what goes on under your skin when a bug bites you is horrifying. Alright, some insects, like certain kinds of ants, are venomous so their bites can itch because their venom contains formic acid, which can irritate and blister the skin. But let's talk about Nematocera, the suborder of insects that includes black flies and mosquitoes.

These bugs have a long bendable proboscis that they stick into you to drink your blood. The proboscis is made up of six different mouth parts. First you got the mandibles which are hooked and the two maxillae which are serrated like steak knives. These sharp bits go as deep as they can to make an opening for the other two mouth parts to pass through the labrum and the hypopharynx. Those are both long, hollow, flexible tubes and they wriggle around inside of you like a worm while the bug probes around for blood vessels.

Once it finds one, blood gets sucked up through the labrum, and saliva is ejected down through the hypopharynx. That saliva is an anticoagulant it stops your blood from clotting inside the bug's proboscis so that it can keep drinking. It is also the main vector for diseases that are transmitted by mosquitoes like Malaria and West Nile Virus. And it has one other awesome property you are probably allergic to it, and when you're allergic to something your body produces histamine, the protein that triggers inflammation and widens your capillaries to allow white blood cells to pass through them so that they can fight foreign.

Invaders. So, it's the histamine that makes you swell up and itch when you get a bug bite, just like it makes your eyes and nose itch during pollen season. We're not even sure why histamine needs to make you itchy in order to do its job. It might just be your body's way of telling you that something's wrong with your skin. But I'm pretty sure we all wish it would stop. So thanks for asking, and thanks to all of our Subbable subscribers who make this and everything you see here on SciShow possible.

DermTV How to Treat Insect Bites DermTV Epi 209

Music Hello, I'm Dr. Neal Schultz pause and welcome to DermTV. A few weeks ago I discussed how to apply insect repellent so you could get the maximum protection against insect bites but the reality is, whether you're using insect repellent or not some people are going to get insect bites. So what's the best way to treat them Well the only reason we really need to treat insect bites is because they itch and when we itch we scratch and that's the problem. Scratching causes three different issues. The first.

Problem with scratching is that while it sure feels good and helps to stop the uncomfortable itching it actually causes more itching. You get a rebound flare of the itching, so you're sort of getting into an itch scratch cycle. The more you itch the more you scratch, the more you scratch the more you itch. Secondly, scratching insect bites can actually cause dark staining of the skin, just the way picking pimples can cause a dark staining and those dark stains are very difficult to treat. And third and perhaps most important, scratching can cause infections in your skin and.

Obviously that's something we'd like to avoid. So the best way to treat insect bites is first of all, with an oral, nonsedating, antihistamine. You can get Allegra by prescription or Claritin over the counter without a prescription. Second, we want to use mentholated lotions or creams to help stop the itching. When menthol touches our skin it causes a cooling sensation and that cooling sensation erases the itching and it feels much better. If you're at home you can take an icecube and touch it with an icecube. Ice will stop the itching without causing any increase in.

Baby Care Basics How to Treat Bug Bites Parents

Bug bites and stings are bound to happen. Here's some tips on how to handle them. For mosquito bites, dab on one percent hydrocortisone cream, a baking soda and water paste, calamine lotion, or diluted tea tree oil to minimize the itch. Bee stings really hurt so be prepared for your baby to cry. Try to keep him still while you scrape the stinger out with a credit card. Try not to squeeze it or it may release more venom. Then, apply a cool compress to reduce swelling. If your baby has trouble breathing, develops hives or swelling, vomits,.

Or has diarrhea after the sting, call an ambulance. If you see a tick on your baby, grab it gently with a pair of tweezers, and pull it out straight. Clean the area with rubbing alcohol. Call your pediatrician if you can't remove it, if any kind of rash develops, if your child seems to be in pain, or has flu like symptoms. Tick borne illnesses can cause fever and rashes weeks after an exposure, so be sure to call your doctor if this happens. Spider bites usually appear as a red raised welt and should be treated with a cool compress.

Bed bug bites usually occur in the middle of the night and you wake up with.

These very itchy bites. Usually on the trunk or the middle of your body than on your arms and legs because bed bugs, like you and I, like to sleep in warm places and the center of your body is warmer than your arms and legs.

The reason for this is, the bed bug bites, has a little meal, walks a little bit bites again, satiated falls asleep and falls off of your body.

The real problem is if you have come home with these bites and they don't just go away and you keep getting more of them, you may have brought some of these pesky little bugs home with you, they travel in your suitcase and they travel in your luggage.
