I'm remodeling & have bare floors, do I drill every 10-12" inside or drill & trench outside
Yes I said the R word... I have the entire house gutted and lucky me, I find old termite activity so I replaced a lot of wood. During the demo I discovered only 2 live termites but that's 2 to many. I called my bug guy & he tells me he would drill every 12"s on the interior slab & then juice it with Termidor. After he told me how much & after I picked myself up off the floor & after I threw him out (kidding) I decided to look for an alternative. Now that I am in this forum I am learning about trenching for the first time... So my question is... Is it better to drill lots of holes in the slab or trench & rod? With my big hammer drill I can punch holes pretty darn quick but from my rough measurements it adds up to over 400 Holy moly's ... Even at the ridiculous rate of 1 hole a minute, (that's Superman speed) I would be at it a while. All that said... Is drilling the slab the preferred method over trenching in my situation? According to my figures 4 gallons over 10' = about 50 ounces per hole... Gosh... I get to have all the fun... Help!
No, you do not have to drill all of those holes. You should not ever have to drill the interior of a slab unless you know there is termite activity coming through a crack in the slab. You should follow the instructions in our How To Do A Termite Treatment article which explains exactly what to do, mainly placing a protective perimeter around the outside by trenching.
