Bug Bite Thing is a family-owned small business established in 2017 that specializes in bug bite relief products.
This works on mosquitoes, bees, wasps, biting flies, sea lice, and more (although TBH, if this list of bugs gets any longer I may just stay indoors forever!!).
Promising review: “I cannot stress to you enough how much better this simple little tool has made my quality of life during summer in Ohio. It rains a lot. There are a lot of mosquitoes. I have horrific allergic reactions to mosquito bites. We’re talking bumps swelling to the width of softballs within minutes of the bite. This tool doesn’t make those bumps go away, but it stops the itch IMMEDIATELY. I was a huge skeptic; how could a little suction cure this agonizingly itchy allergic reaction? I’ll be honest. I still really don’t know how it does, but it provides instant relief that no pill, cream, or injection ever has ever achieved for me. If you live anywhere where insect bites are common, you need to own one of these.” —Customer
