Borax/Borate for Crawlspace


Earnie:
Is your top course of block solid, or filled with concrete? If so, I feel safer about using foamboard, especially since an inspection gap will be present.

Not sure if you are referring to CleanSpace. I did get a qoute from them last year.

From what I can see, the top two courses of brick are mortar filled. Brick is the exterior facade from ground level up to about 30 inches. In the crawlspace is concrete block topped with two courses of the mortar filled brick.

What happend to metal termite shield between the foundation and rim joist? Maybe not a perfect solution but to me it sure beats nothing but straight wall for the bugs to climb up!

Borax/Borate for Crawlspace


The reason Bora-Care is more effective than borax or Tim-bor is that the glycol formulation in the product will allow Bora-Care to re-liquify when termites start building mud tubes on the wall. The top of the mud tube is always moist, the Bora-Care re-liquifies and the termites building the tube start to die. The termites then abandon the tube.

The best solution is to spray Bora-Care in a 1:1 solution (1 part water: 1 part BC) 2 foot up from the ground on to the concrete block all the way around the crawlspace to create a continous barrier. Then spray all the wood two foot out from the foundation wall and two foot our from all the piers. Applay a secont application 20 minutes later to all beams and married joist.

The manufacturer of Bora-Care also makes a termite resistant foam board for this purpose called Bora-Foam - it can be purchased at www.crawlspacedepot.com

So Best solution is
1. Spray the wall with Bora-Care
2. Install the foam board (which is R-10 and has 3 mil poly on both sides) with 3" gap at the top for inspection.
3. Apply a clear 8 mil, nylon reinforced vapor barrier and attach 1 foot up the Bora-Foam
