In reply to: treatment of termites without drilling basement slab posted by Mike K on 16:30:44 4/18/2008 from 188.8.131.52:
I have to tell you, in 40 years, I can count the number of times I have drilled concrete slabs of a basement on the fingers of one hand. Sometimes individual holes, but around here we have some worries with hydrostatic pressure under the slab. And even if there isn't any at the present, there may be a change in the future. I prefer not to drill basement slabs, ESPECIALLY with Termidor.
This is not an exact science, it is an expertise. That means every exterminator has his own way of doing things. That also means that there is not just one right way. They could all be right. They could also all be wrong....
The way I look at it, is the exterminator should use the most efficient and economical way to eliminate the problem as long as he can, without damage to you or the environment.
The "damage" part isn't much of a concern, seeing as how it's farmers that account for 97% of all insecticides manufactured. The farmers, of course, put those on the food you eat, as opposed to the exterminators that put it under the ground.
So the biggest scam in this industry, is the recommendation of unnecessary procedures, and their associated costs. Not to make an excuse, there are many companies that recommend these extra procedures because they're convinced that their way is the best way. It can be confusing....
My advice would go with Termidor, with all attached slabs and dirt fills drilled, treated and patched. It sounds like the termites have entered through the front porch dirt fill. Dirt fills often allow the termites easy access above ground level.
Around the outside, assuming all soil conditions are favorable, the rest of the perimeter should be rodded and/or trenched.
The company should offer you at least a one year guarantee, renewable annually after that. Ask your contractor the price of the renewal and what you can expect for future increases.
I would think you should go with at least that much, any further procedure(s) would depend on local conditions.
