I just put something like this outside, but a jumper I would let stay around to eat flies.
Here is a little crab spider I found, see if this looks like your little friend:
That does look like one..and they can bite, and they are poisionist. (Having been bit by one, and it is no joke how it hurts, and makes you sick)..took 3 mos, and 2 scripts of antibiotics to get over it. Just remember one thing, where there is one, there is another. Better to kill them when you can, inside your home. I put powder laundry soap around the basebords inside my home, year round, leaving it, to prevent pests from coming in from under the cracks of the house this way. It helps, and it works.
I seen that spider in my house also. Probably these spiders just crawl under people's house. Just kill it every time u find one.
I found this spider crawling around and have never seen one of its kind before (in my house at least). I'm just curious as to what species it is and its sex. I thought it might be a bold jumping spider...?
Anyone know?
