Those are pretty prominenet in Oklahoma. If you have other spiders in your home, you will also have recluse's. They feed on other spiders.
Years ago I moved into a country rent house that was empty for about 6 months. I saw a few of them around but thought no big deal. Till one night I woke up with something crawling on my back. I slowly got up, shrugged my shoulders, turned on the light and sure enough, a recluse. The wife woke up, I called my dad and said were coming over, I have a spider problem. Anyway I got the house sprayed the next day. Freakin things were crawling out from everywhere and dying. I collected all I could find on the floor and it filled an 8oz cup to the rim with dead bodies. Talk about an infestation. I never got bit, that I know of, knock on wood.
