Feb 17, 2022

Wolf Spider

These spiders are often found in dark and damp spots of the home. They can be identified by their mix of brown, orange, black and grey colours along their skin. They have four small eyes, two larger eyes in the middle, and the back row of their eyes consists of a pair of medium-sized eyes that face off in opposite directions. They are also nocturnal and hunt at night. They also nest in leaf litter, grassy areas, and small tunnels. Wolf spiders also prefer to be alone, so homeowners don’t need to worry about multiple wolf spiders infesting their home. 

In fact, wolf spiders can be beneficial. They often control other, more harmful pest populations in their area. To prevent them from invading, take steps to clear debris from your yard, seal off any trash bins and clear out any moisture buildup. Despite their friendliness, wolf spiders will bite if they are trapped or handled next to human skin. Luckily, they aren’t poisonous. Their bite will hurt but feel more like a pinch or a sting rather than anything harmful. 

These spiders are also unique in that they do not actually build webs to trap their prey. They are also most likely to enter a home in the fall when the temperature decreases, as they are attracted to warm places. However, they are also similar in appearance to brown recluse spiders, which are incredibly poisonous. If in doubt, contact Pestward to see if an expert can find what you need.
