Comments & ID Thoughts

These littles are all over our house apparently. Found some of them in our upstairs bathroom. This decent sized guy was on the wal going up the stairs. Any idea??

I believe this is a Triangulate Cobweb Spider (Steatoda triangulosa). I live in Canada (BC) and have seen them here as well.

Hi, see above image for ID. 🙂

I have spent most of the night trying to identify this spider and I’m almost positive this is what he is… I’m in Southern California though so I was reluctant to believe. I’ve found at least 3 recently so at least I found someone on the same coast as me. and 2 were found in my bathroom so this would make sense…
