Hi..
I'm trying to find a good way to seal around the pipes that enter our house= behind the toilets and sinks because we're having a problem with ants comi= ng through the gaps between the pipes. From what I remember the hot, cold,= and drain pipes come in through the same hole, their just wrapped together= with concrete right up to the wrap. I'd like to find something I could sq= ueeze into these gaps that wouldn't crush the pipes yet something the ants = won't find tasty. I thought about the Great Stuff Gaps and Cracks but my f= ear is the ants will just start moving into the foam making a new home.
This will probably involve opening the wall under each sink, which if I hav= e to do I'll just add a plumbing access panel so I can get back in whenever= needed.
As for treating the ants, we've tried Termidor (which is supposedly the bes= t), plus we've baited outside to no avail. These pesky fire ants just won'= t let up, so short of doing a costly whole-house treatment of Termidor unde= r the foundation my thought now is to just seal their access into the house= .
Thanks for any advise ...
