Thanks for the wonderful site. I was about to panic, I'm happy I found this site.
A bit of background:
I live in the west side of Canada. I've been living in my house for 15 years or so, it was new when we bought it. We have a variety of different bugs and spiders that occasionally appear, but we never had ants before until a few years ago.
Once was outside in the front yard on the side walk, a definite colony, swarms of ants. I bought these liquid ant baits, and instead of using it properly I just soaked that swarm in the liquid. But soon after, no signs of them. This might be a separate case, but I just want to mention everything that may be relevant.
The problem is we start seeing ants in the house. Behind our fridge was a swarm of ants, and sand-like stuff near the wall (I suspect that is what you call sawdust?). As it was in the middle of the house, not 1 of the "outside walls", I assume that implies they are coming from within the walls. I think we used ant baits, but that swarm of ants seem to be gone now. Or so we thought.
In a closet far from the fridge in the other end of the house, we saw similar "sand" near the wall. And we caught some onesies. But no sign of a swarm.
We keep seeing the onesies and twosies mentioned on this site. We don't see any swarm, does that mean we are safe? Its been 2 years since the swarm situation, but we keep on catching these twosies in the living room. Everyday we'd spot and catch 5-10 in total.
Spring came and we also have these winged ants in the house, caught 4-6 of them just yesterday. This is also the 2nd year this happens.
We also get twosies every few days during winter. I thought ants do come out during winter, so are they living in the house with us?
Can we assume that we have a nest inside our house? I'm guessing in the walls? The fact that we had a previous nest inside the house makes me worry.
And I just don't see any obvious moisture problems I can just fix and hope for the best.
Are we dealing with a nest?
