When I was in grade school, we had gym with our cool, jock guy gym teacher for three weeks and then he turned into our cool, jock guy HEALTH teacher for a week. One of his lessons I’ll never forget was on EAR WAX! He told us that while we are sleeping, bugs can crawl into our ear canals and get stuck. This causes pain and hearing problems. The lesson was that gooey, sticky ear wax, traps anything foreign that flies, crawls, or is blown into the ear canals. Dirt, tiny bits of plant material, small insects, bacteria, and so forth are immobilized by wax. It’s like having a NO PEST STRIP in your ear! The primary purpose of ear wax is to protect your ear canal and ear drum from such foreign materials ...including roaches.
So I did a little research on answerbag.com and found out roaches really do crawl into ears. Happens all the time. What else? Fly larvae, spiders, and earwigs with those scary pincers. Can they get to your brain? Not really … thanks to good ol’ gooky ear wax!
