Which Termicide for Subterranean Termites ?

I have subterranean termites that have entered the house from a few areas: a soil filled front stoop, gas pipes foundation vent and from the soil grade to the sill through mud tubes. The house has a basement on cider block footing. Some of the ceiling joists look like they will need to be replaced.

For a temp solution I have sealed the cracks, fixed water drainage, broken the mud tubes and spot treated area with Permithrin. I realize the termites may go around the spot treatment.

I am considering either Altriset or Termidor for the treatment and to diy this job with trenching the foundation perimeter, drill the stoop and then foam in the interior wall voids. The trenching would be done in Spring and the interior void done now in Jan/Feb. Which Termicide is best? I prefer the lower toxicity of the Altriset if I works as effectively as others such as Termidor. Should Bora-Care be used on the interior exposed wood for a complete kill?

 

Don’t know much about Altriset; just that it is very new. Termidor (or others that use the active ingredient fipronil) is our choice and has been for years. Very safe, effective. It is non-repellent so the termites don’t even know it is present so they continue to work in and thru it, contacting it and bringing back to the colony through “horizontal transfer”. The non-repellency makes it very forgiving in the event that you get gaps in the treatment, etc. They won’t know to avoid the fipronil.

Using bora-care certainly wouldn’t hurt but may not be necessary. If the application site is easy enough to work in then go ahead; especially if mold/fungus or wood-destroying beetles may be an issue. If just concerned with termites, and I felt that I got good soil penetration then I wouldn’t do the bora-care treatment. You could always do that at a later date anyway.

After the exterior treatment consider placing wooden stakes in treated perimeter as monitoring devices. Hammer them into the soil about 8-10”. Check periodically, monthly or so.
