This is my first question here, but I really really need help!
I can't sleep at night knowing.. There are SPIDERS living around my windows, and they just won't die off!
It's becoming summer, and they're going to pop up like daisies! Please, please help me!

I would much rather have spiders living around my windows than flies living everywhere else in the house. You are probably experiencing the result of a recent hatch of "egg case(s)". I would try spraying the area with bug spray. All "pesty" critters require at least two basic things. Harborage (a place to live) and forage (food to eat). Deny them that and they'll look elsewhere. If you can find out what species of spider they are, it will make it easier to "hit 'em where it hurts".

I think it's a common house spider. I've been trying to find a good spider identification site.

I agree with the answer by Kstar4u given above.

I don't know where you live, but here are some sites for identification:

Another thing is, clean all windows and areas around them thoroughly.

I have a picture from last year, there was a big one right in the east window. I very sure it's female, but I could only get a good close-up of her underside.

I live in Massachusetts, so I don't think I have to worry about looking for Black Widows or Brown Recluse. :]
