I stumbled upon your site while googling 'how to make peace with your ant infestation' (there seem to be no suggestions on that, by the way). I thought perhaps someone could offer advice for our particular situation.
I live in south Florida. In March, my husband and I bought our first house. Before closing, I did see a pile of dead ants in a corner of the family room, but the home inspector's report didn't find signs of any infestation, or at least 'wood destroying organisms'.
Once we moved and settled in, I began to realize that there were serious ant colonies on the property, and noticed ants in the Florida room, also in one of the bathrooms. I think in the beginning, they were all dead ants on the window sills and in that bathtub. As summer progressed, the problem got a bit worse. They can walk right through our windows and front door.
I did a bunch of online research, and I'm thinking they are carpenter ants. Not as big as the ones up north, but carpenter seems to fit the description. Because I have a toddler and two cats, my first line of defense was a borax/powdered sugar mix. I scored a big hit when I found old timbers half buried in the front yard near the walkway and removed them, and also pored boiling water at the foundation under a window in the back. We also replaced the weather stripping at the front door, and I've been caulking baseboards and around windows. For about a week, maybe two, it seemed like I was making some real progress, however this morning I saw ants swarming again out front in the morning. Late this afternoon I noticed ant hills surrounding potted plants in the back (near the house). I shook the pots a bit, and ants also started swarming out of the pots, up the trellis, and carrying eggs up into a previously unseen hole in the eave. Great.
I'm not positive, but I think the ants I've seen over the last few days are smaller than the originals, so maybe these little guys have stepped in to fill the void of the bigger ones. Regardless, we have ants in our walls, and apparently in our attic. I know that to truly keep these guys out we have to replace some rotting wood at the door in the back, but our windows are so old that they can literally crawl right through them - the windows themselves, not gaps around them. I have a little one and a couple critters that prevent me from putting down serious poison, and our budget is falling a bit shy of relaxing the doors and windows.
Is there any advice you can give on how to begin to win this battle? The house was empty for a long time, and the responses of ants in different areas let me know that's it's a big ass colony, or that the satellites have close communication.. Any hope you can give me is greatly appreciated-
Thanks for writing! I am glad you are still trying to make peace with ants that live in your house. Most ants are beneficial for our surrounding environment (including yards) - they actually rule our terrestrial world: cycling and bringing nutrients to the surface of the soil; aerating the soil; dispersing seeds; predating pest species, among many other "services". Also, children generally like to spend time observing ants just pass by, or being attracted to a bait, and it can stimulate their curiosity towards our natural world. You can read more about how good ants are here.
If after all you think its better to get rid of your crawling roommates, you should know you are already doing some of the most effective things to eradicate them from your home, and here you will find important information on baiting. Further, you can drown ant colonies in the plant pots, using warm water, and leave some clove sachets in strategic areas of your home (like in the food shelves) to repeal them.
If you really have carpenter ants, this may indicate you have a more serious problem, because they often build nests in compromised wood. I would first be sure they are really carpenter ants - try this and this for identification; and, if positive, you can try this to eliminate them from your place.
Please, look for more tips here, and have a good lucky in your endeavor!
