After digging the trench and treating the whole house for termites can i use crushed rock/gravel foe the backfill? For ease of future treatments instead of digging the trench again in 5-10 years couldn't we just pour through the gravel?
You do not want to use grave/crushed rock as your backfill after a termite treatment. Termidor does not bond to rock, it bonds to soil, so if you fill in the trench with gravel, the termidor will not stick to it and it will leave you with a 6x6 area of completely unprotected surface that the termites could pass through to get directly to your home. We understand that the digging of the trench is a pain, but it must be done each time and it must be backfilled with dirt, and the dirt that is backfilled must be treated as well if you want your home properly and completely protected.
