What can I use to get rid of ants that are trailing up my home and into my attic?

I see ants climbing the outside walls on my house and going into the vents on the house. I sprayed the vent with and killer, and they appear to be gone, but in a few days they come back or will been seen coming and going through another vent. I set off a few foggers in the attic, put out terro and bait which killed many of them but not all. Is it possible the colony is in the attic? It's a constant line of ants going in and out Any advice would be appreciated. I have been told ants are very bad this year where I live.


Ants will build nests where ever they can find a suitable area to do so. While it would be unusual to have an entire colony in your attic, it is not unheard of. The good news here is that the ants are visible to you and they are still going outdoors to forage which means they will walk through areas that that you treat outdoors. We recommend you use a product called Termidor SC around the exterior of your home. Termidor is the # 1 choice for ant control around the home. Termidor is a non-repellent insecticide that works with a delayed reaction amd also has a transfer effect. That means that ants cannot tell that the Termidor is there and will walk right over it and then pick the product up on their bodies and inadvertently carry it back to the colony, then through normal social interaction the ants spread the Termidor and wipe out the colony. Termidor only needs to be applied two times per year and is effective for a wide variety of insects including ants, centipedes, roaches, spiders, silverfish, wasps and many other nuisance insects. You will need to apply Termidor SC 1-2 ft up the foundation and 1-2 ft out onto the ground, around door frames, window frames, places where cables, pipes or wires go through the wall and any other crack or crevice where the ants can gain entry into your home.
