In response to a PP - not all spiders spin webs. There are species that don't. In Brazil, where some spiders are venomous, we were told that as a general rule, spiders that spin webs aren't toxic to humans. They don't need venom as the web does the work. Spiders that don't spin webs tend to be venomous, as that's their main weapon against prey. (For example, the Brazilian wandering spider is very venomous, and I don't think they spin webs. There are exceptions to this rule, though - Australia has a species called the Sydney funnel web, which spins a web but is one of the deadliest extant spider species due to its venom.)
Hubby deals with the spiders in our house, but they are usually pretty small. I think Alberta does occasionally have some venomous spiders, most commonly the black widow, but they aren't very common. Our cats are pretty good at dispatching most household pests. Hubby once said to me, "Jayda has found a spider. I think she's going to eat it." (Struck me as funny, just the way he said it. I'm not sure why.) My kid once brought Gatsby into the bathroom to dispatch a small moth, which he proceeded to do and apparently enjoyed eating.
