Our bug guy came out yesterday and sprayed a chemical around the pipes in t= he kitchen and both bathrooms that will pretty much kill the ants on contac= t. The sand traps still have Termidor which will hopefully keep them at ba= y there, but we'll see if this along with some extra bait along side the ho= use will work.
The bug guy did suggest that when the weather gets to the 70's and 80' to p= ut some potato chips on the ground around the house and see if the ants com= e out to forge. If so put some Amdro around the area and see if they pick = that up to carry back to the nest. If we can definitively get some of that= to the queen(s) that should hopefully knock out the colony.
But thus far we're seeing fewer and fewer ants each week, so hopefully the = spray he put down yesterday will help keep them at bay for the time being a= nyway.
