Do we need to remove the pavers and trench then apply Termidor SC, or can we use BoraCare sprayed on the pavers and foundation wall to prevent termite access?

We have found a termite tube on the concrete foundation wall (exterior) in our courtyard. Our courtyard consists entirely of pavers. Do we need to remove the pavers and trench then apply Termidor SC or can we use Bora Care sprayed on the pavers and foundation wall to prevent termite access?

Answer:

Boracare is only labeled to be used directly on wood so this should not be used on a concrete wall or paver. For your concrete areas against the home, you will need to get the termiticide underneath the concrete against the foundation. To do this you will need a hammer drill with a 1/2" x 18" drill bit. You drill holes throughout the concrete about 3-4 inches away from the wall or foundation, and about every 10"-12" apart. Once the holes are drilled, you fill at the same rate you did the trench, 4 gallons per 10 feet. To fill these, we would recommend using the one gallon sprayer on a "pin stream" setting so you can force the liquid down the hole and not splash it everywhere. You can also use a funnel and pour the termiticide down the holes. It is difficult to get 4 gallons per 10 feet in the holes, so it is important that you use a long drill bit, at least 18" long so you can bore out enough dirt to hold the termiticide. Once the holes are filled all you need to do is patch them with a concrete patch filler you can buy at Home Depot or you can use our Trebor plugs that will close the hole with no concrete mess.
