Spider found in house in south east Ontario, Canada

Belleville, Canada

Hi everyone,

I found this spider on the wall a few inches from the ceiling in my house in Belleville, Ontario. I have never seen anything like it, and I have spent about an hour now trying to identify it. I have had no luck and thought I would turn to people who know more than I do. Can anyone help me identify this spider? If so, should I be concerned about it, and maybe others, being in my house?

Any help is greatly appreciated!

Sorry if the close-up pics are a bit grainy. The little guy moved way too fast to get a good macro picture of him, so I just zoomed in on the ones I was able to shoot.

Male cobweb spider in genus Steatoda; maybe S. triangulosa. Harmless.

Thank you!
