Battling ants in winter (Christina, Kansas City)



We have been battling ants for about a month now and I'm just curious if we need to take it to the next level (ie- call in a professional) or if we are on the right track.

First, some background, we live in the Kansas City area, and we've had a fairly mild winter up until about a month ago. We have had 3 snowstorms in the last month, all producing more than 6" of snow (two with more than a foot!). The first two snowstorms were 5 days apart and we first noticed the ants between those two storms.

We have a split-level home, and I first noticed the ants in our dining room area, and as I started looking around more, I realized they were everywhere. In the dining room (which is connected to the kitchen, but they weren't trailing to any food in the kitchen), they were also in our front living room near the window and the fireplace, they were also in our walk-out basement. None were noted in the storage room (where the dogs and their food are), or any of our bedrooms which are on the same level as the kitchen/dining room.

Initially we sprayed indoors which I now realize was foolish. We couldn't spray outside because there was collectively 2 feet of snow after the first two storms. After doing a bit of research I decided that the terro traps were the way to go (because we were still seeing live ants every day). We went out of town on March 1st, and we laid terro traps in the areas we'd been seeing the ants. We were gone for 10 days, and when we returned, there were THOUSANDS of dead ants all over. The most concentrated areas were near our fireplace, the front window, and near the door to the walk-out basement. I vacuumed all of the dead, and continued to see new live and dead ants each day, but the numbers slowly dwindled over the following 2 weeks. I also sprayed the perimeter of the home (outside) once the snow melted. I felt like we were finally getting ahead of the game because it seemed like we weren't seeing any more accumulate.

Then out of the blue this morning (after our third snowstorm happened overnight last night) I noticed a few more near the front window, however they were different. Instead of being small, black (what I think were odorous house ants), there are a fair number of dead, larger, winged ants. They have a good waist to them, so I don't think they are termites, and they are all dead, or almost dead, no swarms.

My question is, is this a good sign? Have we killed enough that the end of the colony is coming out dead? Or is this a bad sign that more breeding ants are coming out and developing new colonies? We continue to have the terro traps in place and have not given up the battle yet. I just need to know if it's time to call in a professional, or are we making progress and just need to keep at it?


Dear Christina,

It is hard to say but it is very possible that you are on the home stretch of ridding yourself of these ants. Oftentimes, when ant colonies are on the verge of death due to depleted resources, disease, or attacks from other ants, they will devote their remaining resources to producing winged reproductives in a last ditch effort to reproduce before dying. Therefore, the colony occupying your house may be teetering on the edge of collapse.

Good luck! Hopefully an exterminator will not be necessary!
