I don't mind spiders, it's daddy-long-legs that I hate... uuurgh...
I had a look and sadly it doesn't say anywhere about spiders. It just says insects. As spiders are arachnids (8 legs) and insects are 6 legs, I'd guess it doesn't... But as I said, if there are no wee insects in the house the spiders will have to go elsewhere for supper!
