Ok bitsy, Thanks for the help on the spiders outside my house. We will only last until the end of April and move out. My question is, are this spiders also widows? These are all over the inside. Have seen 4 dime sized ones and the rest are half of that size. I want to know if I have to worry that these might be widows also and be carried on sofas or appliances to my new place. I appreciate your help since I have 3 small daughters.

Okc, 
Hi, what I can see of this one looks to be a Triangulate Cobweb Weaver, Steatoda triangulosa. As long as you’re not finding them in your bed sheets or laundry I wouldn’t worry about them, they’ll prey on less desirable things. They’re well established throughout North America and Europe, you might have to travel pretty far to get away from them. 🙂
You can reduce the number of spiders you see in your home by sealing cracks around floors, doors, windows, foundation etc., vacuum everywhere and empty the canister outside.
Do I need to worry about venom and such? How hatmful are these. Awfully, these spiders are everywhere. That one was climbing back to the window when I decided to take a shot and ask you before tossing it to the trash.
Everyone’s immune system is different so I don’t know how you would react but relatively speaking these are really low concern.
