I am freaking out over carpenter ants in my second floor bathroom. I'm in Vermont, and never had them before. For several nights, it was two or three, then a couple nights ago it was about a dozen. I think they're coming in from the hole where the toilet pipe comes in. A couple ran under the tub where I removed the caulk to recaulk it. Now I'm afraid to seal off the toilet pipe hole with expanding foam or even to recaulk the tub.
I checked outside, and directly under that bathroom is a set of french doors. On either side, I noticed the wood was rotted at the bottom where the frame met the concrete step. There are holes, and I witnessed carpenter ants going into the hole mostly on the right side and heading upward.
Do I have a serious infestation, or can I just seal up the outside holes so no more come in? Should I pry off the wood and have a shop vac handy?
I did put a little borax under the holes, but they're still active.
Please help! Thank-you!
