I sprayed bleach under my sink (for a leak that molded the bottom of the cabinet under the sink). A spider crawled/limped out (a big wolf spider). I still feel bad but had no clue there were spiders living there. Prop would have felt worse knowing they were living in my space-LOL). Those spiders - not something I like. No priss here, can sorta handle snakes, but with wildlife, spiders and snakes are my line. Way back 25 years ago, sprayed a big wolf spider with hairspray (it decided to appear in my bathroom) sprayed it til it froze. It was kind of it or me freezing - still feel like the worst person on earth for torturing one of earths's creatures. Should never come to between earths own.
