Chemical-Free Way to Ease Itching from Bug Bites The Bug Bite Thing is a device that uses suction to "extract insect saliva/venom from under the skin." It is a very effective way to ease itching and swelling from bug bites (Mosquitos love my family). It is also recommended for stings, but we haven't tried it that way yet (knock on wood). Made by a mom. This is a chemical-free solution to help deal with annoying bug bites. I wasn't sure it would work, but I just ordered more after my daughter asked me to get another one she can keep in her backpack.
