We are constantly finding small black spiders in every part of our home. We have had the exterminator out two times in the past month, but they persist. My biggest fear is that there is a nest somewhere and soon, we have a hundreds of them crawling around. They are all the same size and are freaking me out since I have a huge fear of spiders in the first place. What can I do?

That does sound like there is a nest if there is that amount of spiders. Maybe try another exterminator? Or phone up the one you had and tell him you still have the problem.
