Hello Pam,
If you hired an exterminator, they would tell you that they cannot guarantee eradication of Brown Recluses. They would spray, but to help eradicate the spiders they would set out traps. You can save a bundle by setting out traps yourself. With our traps we include an information sheet of the best places to put them.
A significant decrease in population is possible with traps but complete eradication can take a year or more. This is because the females tend to live inside walls and don't move around much. The more traps a person sets though, the quicker their population will decrease. It's simple mathematics that the more traps a person sets, the more opportunities there are for a roaming spider to get caught.
*I* personally wouldn't have a problem sleeping in a Brown Recluse infested home because if I do get bitten I know personally how well the Brown Recluse First Aid Kit works. I'm sure that I could be accused of bias or trying to sell something but I really am that confident in our product. We actually don't even try to rid our home of the spiders because we like to capture and study them. My teenage son was bitten a couple years ago several times on his thigh when he was putting pants on, but we used the kit and everything was fine...no pain, no necrosis, nothing.
Overall, my advice would be to set out a lot of traps before you move in the home, and for the toddler it would be a good idea to make sure his bed isn't against any walls and that the only access a spider would have to his bed is the four bed posts touching the floor. They might not be able to crawl up smooth textured bed posts, but either way putting a trap near each bed post would be a good idea. You can also follow the prevention steps at
