Martin from Leavenworth Kansas writes
No matter whether your home sits on a slab, crawl space, or basement the 6x6 trench is all that is required around the outside of the home along with any drilling you may have to do through concrete barriers like patios and driveways. Inside the crawl space you would need to trench around any piers that hold up the home but the outside trench would be all that is required for the actual foundation if you are using Termidor SC. If you use Dominion 2L, you would have to trench the inside and the outside of the crawlspace foundation as well as the piers. The Termidor SC will last for 10 years to protect your home and the Dominion 2L will last for 7 years. Please let us know if you have any other questions and you can review our article on How To Do A Termite Treatment for more tips on doing it yourself.
