Thank you so much for your reply and advice. I have some more information since I last posted. I think it is definitely the master bath area that is involved and the stall shower. I believe that to be true because of seeing the ants come out of the heat register which is on the same wall as one side of the showe,r and because yesterday I saw an ant come out of the ceiling fan in the downstairs half-bath--he crawled out and dropped down to the floor of the half bath. The ceiling fan of the half-bath is almost directly under the stall shower of the master bath.
The weather has still been cold and we had 3 inches of snow last night, but instead of being in the teens and 20's, the temp hit 30, but still to cold for ants to want to go outside. However, yesterday I saw only 8 ants all day (and 1 of them was dead). Today, at almost 7pm, I've seen 5 so far. So for some reason the number is down quite a bit. I'm hoping it's because they are dying from the Cy-kick and the ant bait the exterminator put under the master bath vanity. I talked to the exterminator yesterday morning when I was still all upset from finding 49 or so on Thursday. He is coming back on Monday to treat in the two walls of the master bath where the shower is. He's not charging again because of his warranty. How do you think he should treat them? He said after Monday's treatment we need to wait at least 30 days and see what happens and then in the spring as soon as it's warm enough for ants to be foraging outside, he wants to treat the perimeter of the house. He said after that we can decide if we want to be on a spring/fall outside perimeter spraying plan which would give us an all year guarantee. I think he's familiar with Phantom because it is listed on the receipt I received as one of the chemicals he uses and termidor is listed too
I also think the shower is involved because yesterday I removed some old caulk that was starting to deteriorate (I had caulked around the perimeter of the base of the shower about 7-8 years ago because the grout started to crumble in some spots) and re-caulked all the way around the base of the shower. Today all the caulk was dry except in one corner which was as soft as when I first applied it--this is also the area where the grout had been the most crumbled. This makes me suspicious that maybe some moisture is getting behind the tile and through the pan, but not enough to wet or stain the drywall on the ceiling below it. We have never had water spots and I would see them because I am always looking when I clean and my husband has repainted and he would have seen water spots. I'll call a plumber/contractor to come and check.
I'll let you know how all this turns out. If you have any other suggestions/advice of what to check or what to talk to the exterminator about (other than what you've told me, please let me know).
Thank you so much for your message board and sharing your knowledge--it takes time for you to answer our questions and I want you to know how very appreciative I am!
