Stillhope...We rented in Post & pier & bought slab. You will see people adament about each, for us, it was more of what was here at the time....
This slab house was loaded with dead creepy crawlies (including rats & mice), but we added door sweeps, sealed off holes in the walls, caulked & did many things that you gotta do to a house in the northern midwest. In over 2 years, we have had very few bugs (BTW, ANYTHING you bring into the house could have some hitchhikers....esp. roaches... inc. boxed items bought in a store!) Due diligence & a vacuum handle most things....
The itty bitty tiny ants & fruit flies are the things I have noticed. Pet food & fruit on the counters are the main attractants. Our cat bowl now is two bowls, one slightly smaller bowl in a larger bowl with water (the ants can't swim, as far as I can tell...)
We use very little chemicals, Boric Acid at the wall base seems to keep most things at bay, along with ant & roach baits (in little plastic holders...) But the termite damage was done....& I am not sure that we could have kept the ground termites away with our arsenal...
Ground termites attack both slab & post & pier... I think due diligence is needed for each.... The neat thing with slab is IF the Basaltic base keeps out ground termites as the UH studies indicates, then there is a no chemical prevention for new slab construction. No way to add the new base under old slabs
