Comments & ID Thoughts

Good Morning!

If anyone has knowledge of spiders and could help me identify whatever these are that I've found running quickly in my brother's house. He lives near the water way and we haven't seen any webs. It only allows one picture but I have a couple. I don't like killing anything but if this is dangerous to people or pets I need to know because I've seen more than 2 in the last week run through the den.
Cheers!

Hi, welcome to Spider ID. 🙂 This is a male Wolf Spider (Lycosidae) likely wandering in search of a mate. Looks like either Tigrosa georgicola or Tigrosa helluo, hard to say for sure which given the condition it’s in. Like most spiders they have venom but are unlikely to bite except in self defense and are not considered to be of medical significance.

Not too unusual, they’re not really an indoor species though so they’re probably wandering in somewhere by mistake. You can keep spiders like this out by sealing cracks along floors, foundation, doors, windows etc.

Yes, it’s the spray that’s making the spider look darker than normal which makes it difficult to make out subtle details.
