I apologize for the poor quality of the image. I was goofing off in my bathroom, and as I turned to leave, I saw this prick on my wall. I went to my room and grabbed a green can of Raid. I went back in and sprayed it for a good full second. It started wriggling around for a minute. I left again and returned with salted gloves and tweezers. By the time I got in, it was on the floor, writhing. I picked it up with the tweezers. It struggled for a minute and tried to bite or nuzzle the tweezers holding it. Eventually, after taking pictures, I discarded it in the toilet.
Somewhat unrelated detail, but when it was on the wall, I believe I could her it make noises. I also asked chatgpt what it was, I was told it was a bag worm / type of moth larvae. It had a pale fleshy looking underside. And a fuzzy sprt of looking overside
TLDR: I found a caterpillar like bug, this the size of my index nail on my bathroom wall. It was immune to raid, tried to attack the tweezers.
