I just had a spider of some kind scurry into the middle of my bedroom. I went to the other room to grab a spider smashing shoe, and of course, the friggin troll disappeared. I then see it later scurry under my utility closet door. Don't you hate it when creepy crawlies do that? Ps. I'm looking for the best bug spray known to man, with the purpose of spraying under a door to keep them from coming through. Basically, the "utility closet" also leads to a crawlspace, and that's where they keep coming in from. My understanding is there's such a thing as a "bug spray pee line" that can last a long time, is that true?
