If needed, spiders can be killed by using a fly swatter, rolled-up paper, or magazine. You can also trap live spiders with a glass jar and a piece of stiff paper and then release them outdoors. If there is a spider near a door or window, chase it outside with a soft brush. Keep clothing, shoes, and blankets off the floor so that spiders do not hide in them during the day. Sweep behind washers and dryers often and rearrange furniture once in a while to prevent spiders from spinning webs in the same place. Remove spider webs when spiders are not in them. Sweep or vacuum baseboards and corners of rooms often to remove any food crumbs. If you are concerned about the potential presence of black widow spiders, be careful when working around spider webs in secluded areas, and wear protective gloves if needed. There are a few black widow species that can be found in Canada, mainly in the southern parts of the country, but they are not common. It is not aggressive and prefers fleeing when disturbed, so it will only bite to defend itself. It spins a small, silk web close to the ground and is found in secluded places like garages and sheds, or under rocks or fallen trees when outside. It is shiny black, with a distinctive red hourglass-shaped mark on the underside of its stomach. The black widow spider is rare in Canada, found mainly in southern regions along the Canada-United States border. It builds webs in dark corners, under furniture, and anywhere insects might be caught.
Its first pair of legs is almost three times the length of its whole body.
The house spider varies in colour from dirty white to nearly black, with visible markings on its body. The house spider is more commonly found within the house, whereas the black widow spider is more likely to be found in dark crawl spaces, garages, or outhouses. The house and black widow spiders belong to the same family.
