Roaches

Roaches

I know there have been related posts before but for some reason I can't find them. I bought a foreclosure house a few weeks ago and have been getting it ready to move in... it was in liveable condition from the start (or so I thought) but not the best, being as it was a foreclosure... There was what I initially thought was a minor bug problem. Before I started doing anything else, I bug bombed the place with the recommended number of foggers, and a week later I did it again (I've always heard that's best because of the egg sacs on the dead roaches still being able to hatch. There were still roaches. And not the big wood roaches that are creepy but mostly harmless, but the small German roaches that are just nasty. So, I doubled up on the number of foggers and did it again, and I also set one off in the attic. And there are still roaches. Since that last time, I set off MORE foggers, triple the recommended number this time, and sprayed with this commercial strength mix up stuff you buy from a feed store (mixed it at double the recommended strength)... I sprayed all along all of my baseboards, around the windows and doors both inside and outside, I sprayed the crawl space under my house and the piers that I could get to, all of the trees in the yard... I also put boric acid and moth balls underneath the house because I've been told that's good to do. I did all of this Tuesday, and yesterday (Saturday) THERE ARE STILL ROACHES! I honestly don't know what else to do. Exterminators are expensive, but maybe there's some sort of treatment they can do to get rid of the roaches that I haven't been able to find? But to get a guarantee, I've heard you have to sign up for a monthly maintenance plan and I don't really want that. Someone recommended gel bait that's supposed to work well, but I've already put sooooo much money into getting rid of the roaches and don't want to spend more on something that still isn't going to work. As far as I can tell, I don't have any sorts of openings in the house they're able to come in through. How do you kill the roaches that live inside the walls since that's most likely where they're nesting? The other problem is that I haven't moved in yet because of the roaches, and I'm also paranoid... after I treat AGAIN, I'm not really going to have a reason to hang out long enough to know the roaches are gone but I don't want to move in until I'm fairly certain they are. How do you check that? I live with family so I'm not having to pay rent and a mortgage, so while I want to move into my new house ASAP (why pay a mortgage on a house I don't live in?), it's not absolutely urgent financially... So if anybody has suggestions to get rid of some roaches that refuse to die, please... share!!
Please tell me this could be the work of squirrels.
