This particular site seems quite informative
Erradication
One thing I found of interest was using sticky boards or strips in areas where you suspect they are living. That would tell you were to look and where to send the pest control people.
We had a number of brown recluse in a basement apt we lived in a few years ago. One thing this article mentioned was that they liked to live above suspended ceilings. The entire ceiling in our place was a suspended ceiling and I suspect that's where the worst infestation would have been found. I did find that our back door seemed to have cracks around it that were quite wide. We never used that door so I duct taped around the inside. Yeah not exactly attractive but neither is a brown recluse bite. It did seem to reduce the numbers of bugs in general when I did that.
Also, as the article said, reducing the other creepy crawlings in and around your home will attract fewer spiders. If there's no food they will quit coming.
I thought they really covered a lot of different things you can do to eliminate or at least reduce their numbers. Then when you call in a professional once again they may be more effective.
I remember hubby getting a bite and it took months to clear up. That gotta suck. I wish you good luck in getting rid of those creep crawlies. Outdoors? or non biting spiders in a couple corners of my house I don't mind. Indoor spider that bite me? Forget about it - it's all-out war.
