I tried to kill a spider with air freshener once. It didn’t work. Eventually (and by eventually I mean several hours later) I plucked up the courage to use a shoe and get close enough to kill it. It was on the ceiling.
I’m hoping that the hairspray will make him sticky enough that he can’t get far but he crawls onto a wall so I can kill him and sleep without the terror of waiting for a mutant spider to attack.
