My wife used to be a sales rep for an anti-pest device that is mounted to the outside of the house and sprays a chemical into the air at predetermined intervals. She recently told me a story of this ridiculously rich woman who wanted a system installed on the interior of her home (LOL) because she had a brown recluse infestation.
I'm seriously thinking of getting one for my new house. It would break me financially but at least I'd be able to go outside again. I get fucking destroyed just sitting on the porch.
