How can I prevent ants coming through the plumbing holes in the slab?
A little history here. 3 years ago I had my shower redone. The plumbing for the shower and tub share a common wall. When they took down the wall there was a huge ant mound in it. I took out at least a 5 gallons bucket of ant mound. I found that the original builder did not fill in a hole under the tub where the drain goes through probably 12" x 6". I cleaned it out and flooded it with termite & ant spray. The shower contractor was supposed to fill it in before they put the wall back in.
I started noticing ants again recently. They get into food in a pantry that shares the common wall. I suspected that the contractor didn't fill in the hole. This morning I cut a hole into the wall behind the refrigerator. The water for the icemaker comes from the same pipes.
Well I dug out another 5 gallon bucket of ant mound! The hole under the tub looks like it's been filled but I haven't been able to clean it out well enough to see how well. The ant's are active & pissed now. I sprayed down everything again will get it cleaned out later.
It looks like the ant's came through the plumbing this time. The pipes are wrapped with a red plastic close to the slab. I think this was supposed to prevent this. There are multiple pipes coming through the slab tying to 2 hot & cold pipes. Not sure the reason but I'm sure a plumber would.
Thanks Mike
