Termite and termite inspection problems

[Carey]

Have you looked at the Basalt Termite barrier that was developed by UH? It is a non-toxic physical barrier of sieved basalt fines at a certain size that does not allow subterranean termite to move through it (it is sold in bags at HD, if you want to see what it looks like - we used it in all of the slab plumbing perforations on our remodel/

not sure about the barrier you are looking at, but here we also have drywood termites that do not use ground, so if it is ground treatment, you will also need to plan against the drywoods...
