@Rockhead,
The pest people will talk with you, they did for me.
At the time I was looking to get rid of roaches - outside. We do it ourselves now but it cost $55 to have the guy come around, spray all around house, attic and garage.
Funny, I've always sprayed my house indoors with Home Depot's family spray, doesn't cost much. Never hurt a cat. We used to live in the boonies in Michigan, got lots of earwigs both inside and out, moles galore. Never did get rid of those moles even after I fed them chewing gum, castor oil, anything else we could think of. The cats just sat there and watched them throw dirt in the air.
I used to have this little nutty cat where we rented a house on the lake here in TX. She would sit in the living room all night watching for spiders and scorpions. They slap them with their velvet paws (spiders). I don't know how she killed the scorpions.
