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 bought this because I saw it on TikTok, and have been having issues with mosquito bites. Used it a few times to relieve itchiness and I am convinced it works! Have been recommending it to my family and friends. Read the directions and follow them carefully. Don’t use this on your face or neck, or other sensitive areas. Don’t do a lot of suction, just a little bit. And do it a few times if needed. Great invention!” —Joe
