Found about 5 of these in our basement this week. It's dark and damp. No known webs. Just sitting on the floor.

Help identify this spider
Hi, this is difficult to recognize given the condition it’s in. What I can make out tentatively looks like a Wolf Spider (Lycosidae), more specifically Tigrosa helluo.

You can reduce the number of spiders you see by sealing cracks around floors, doors, windows, foundation, etc., vacuum everywhere and empty the canister outside.
That’s worrisome. We live in a 100yr old house. There’s no way to seal it up..we rent. Can they do harm? My children have a playroom down there.
Have you discussed it with the owner of the building? I don’t know if you have legal protections, your basement probably isn’t considered an “ occupied living space.” My rental neighbors work deals with their landlord where they provide the labor if he pays for materials.

The only potentially harmful spider in your region is the black widow which is relatively easy to ID by being globular, black(very dark brown) and having a red hourglass on its underside.
