We have one nest, that we know of, in the front lawn. Smaller ants, with the little white things -- eggs, or larvae? There is another very large anthill at the foundation in front of the garage. Larger & medium size ants, some with the rusty thorax; pupae & winged ants appeared (under the ineffective traps) last week. There are ants at the diagonal opposite corner of the house along the foundation but no visible anthill yet. Ditto re colour & size. In between, we have dozens of ants -- large & medium size -- on the kitchen counter, along the cupboards, on the floor... at that end in the basement (nearest the big nest) there is one gap in the floor (plywood) against the foundation where they appear to be entering. At the other end, they are appearing in a corner of the basement ceiling, & appear to be coming down through the foundation & through the insulation. They are also going up from that point into the bedrooms -- dozens in a day, & getting into the bed as well. They may be anywhere in the house in between. We found a pile of insulation & dead castoffs in a spot further along the basement ceiling, under the other bedroom; little activity there. I suspect they are travelling in the walls.
We have learned, from experience & subsequent research, that the hardware-store ant traps are useless. We tried digging the tops off the 2 anthills & drowning them with hot water. The survivors rebuilt. Today we tried a Raid spray foam that you put down the holes. Waiting on results. We are not sure where else they may be coming in or where the main nest may be. We are 2 elderly, frail & sick people & an exhausted caretaker who can barely get through the routine of a "normal" day -- this is driving us crazy, & tearing apart the house to repair dampness (which probably exists along with lots of crevices; the builder's skill was questionable) is just not possible for us at this time. The one exterminator on our isolated Canadian island is, from acquaintances' comments, not very effective. He charged a friend $400 to spray the tops of some nests in her yard, & they are all still active.
Do you have any advice for us, & is there ANY kind of bait that we could find in Canada that is known to be effective for carpenter ants? Many boast great claims but we understand many are useless.
Thank you very much, for your time & for -- no doubt -- answering the same questions over & over for newbies!!
