Is it safe to apply termidor foam to an opening in a brick wall that has a radiator pipe going through it?
I have subteraneam termites in a finished basment in an 1860's brick house in upstate NY. I removed the sheet rock and baseboard from the wall where they seemed to be coming from after we had swarming for A MONTH, and I found all the wood at the floor (the base for the sheet rock against the brick) to be completely eaten, and there was mud everywhere - and of course thousands of termites. I followed their trail through the wall into the next room room, removed baseboards, and found lots of mud and evidence of eaten subflooring (the second room has linoleum over plywood, on what appear to be 2X3s - it's at least two inches higher than the first room that's tile on top of cement.) The basement is dry and has been measuring 20% humidity generally.
The estimates I've gotten so far are 1) termidor foam in one wall (the wall I have since taken down) and 400 gallons of termidor piped around 3 sides of the house (he didn't suggest drilling the driveway) for $2700, and 2) termidor foam in one wall and 10 advance bait stations outside for $2400, pus $400 a year to maintain the stations. These are pre-tax prices. The first bid sounds like it should work, but isn't as thorough or targeted as I'd like. The second bid seems absurd given the price of the materials and the amount of labor.
Now that I'm in the process of actually removing some wall and baseboard - and perhaps some ceiling to make sure they haven't gotten up that high and are at the beams - in order to try to figure out exacty where they are and what they're doing, it seems to me that I can apply termidor foam in the spaces I've opened up between the wall and the floor, and then put on new baseboards pre-treated with bora-care; apply termidor foam into the 2" space under the linoleum floor; use bora-care on all the exposed bare wood; install advance bait stations outside, and probably do a pretty good job controlling them. BUT I'm wondering if I shouldn't apply the foam around the 5-6" of pipe that go through the brick wall, even though it's obvious from the mud etc that tehe termites have been using the hole as a thoroughfare.
Your site and your advice are INCREDIBLE. I'm so sorry this is much longer than I anticiated, but you seem like one of the very few genuine experts who also is frank and honest. Any help is apprciated before I pace my orders. Thanks so much, and stay safe!

The first problem you have is the none of these products can be shipped to NY. The Unions and State of New York Restrict all of these products to purchase by a licensed applicator only. If you know someone out of State who can purchase these products for you, then you could proceed.
As far as your treatment plan, it sounds like a good plan. The idea here is to treat wood, and not open spaces. So blindley pushing foam under the floor is not a good plan, treating the exposed wood where the termites are feeding or entering is a good plan.
My recommendation is to use Termidor in every place possible, limit the use Bora Care or even not use it. Termidor works very differently than Bora Care and will control the termite colony. Bora Care will not, it only kills termites that eat the treated wood. Very limited as to how it works.
Also, be careful and do not treat any areas where air circulation could result in vapors from Termidor or BoraCare being pushed back into the living space. If the Radiant Heat Tube does this, then don't use anything in this area.
Hope this helps.
