Entomology (Study of Bugs)/Wolf spider diet



I live in southern Alberta and my basement has been home to quite a few wolf spiders since we moved in.
I'm not particularly bothered by them but I'm puzzled about what they're eating because I've never seen any other bug down there except the said spiders.  Oh, and if I do decid to make war on the Arachnida will I just be overrun by whatever they're eating?


Dear Daniel - Wolf spiders basically will eat anything that they can overpower, including each other. And as they are quite active hunters, they very commonly will wander indoors during their searches for prey. I think that you are quite safe in just letting them go about their business, but you always could just shoo them into a container and escort them out doors if their presence bothers you.

Hope this helps,

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
