Doesn't work for spiders!
Well I installed one, waited a week and was up in my room it is installed in last night and what do I see a spider coming down from the ceiling.  AHHHHHH!!!<br /><br />Now I bought them to keep the stinkbugs out and I haven't seen any since I installed it but it has only been a week.  But it states it keeps spiders away as well.<br /><br />Also they are really big and it fills up an entire outlet, which is inconvenient for some people.
