The Ardap Spray is really a great help when you have a total arachnophobia. I spray it from the inside of the window frame and the whole icky creepy critters die on the way to my apartment, so I only need wicking (Also helps with flies, mosquitoes, etc.). The same I'm doing in small corners or crevices where the animals always out so otherwise crawl. Since I'm not surprised by giant spiders more. This helps me tremendously. I've never tried another spray, I also do not have to and I do not want. clearly it smells funny at first, but once you well ventilated half an hour, it is as would have been nothing. Lasts about 2 months, then I spray again - sometimes 3)
