House Spider
The species behind most small messy webs you find inside Ontario homes. Common in basements, garages, attics, and behind furniture. Harmless to humans.
Body about 5-8 mm, dull brown with darker markings. Round bulbous abdomen. Builds small, irregular cobweb-style webs in corners, behind furniture, and along baseboards.
Throughout the home but concentrated in low-traffic areas: behind furniture, in basement corners, under sinks, behind appliances. Active year-round indoors.
No. Bites are extremely rare and have no significant medical effect on humans. They are beneficial in that they eat other insects, but most homeowners would still rather not host them.
Exterior perimeter treatment is most effective. House spiders enter through gaps in window seals, basement vents, and door frames. Treating these entry points and the foundation perimeter cuts off recruitment.
