Discover the most effective ways to identify and eliminate ants in your home.
For such tiny pests, ants can pose a giant nuisance for your home. While ants serve their purpose in the outdoor environment by eating other potentially harmful pests, these pests serve no purpose indoors. Killing or getting rid of ants you find in your home can be tricky because of their large numbers and industrious work ethic.
Learning how to identify ants and understanding their habits are important, but the key to getting rid of ants is to kill them and their nests both inside and outside your home, and to prevent them from coming back.
In the United States, there are more than 7,000 types of ants. In general, you can identify ants by these characteristics:
Some of the more common ants found in the United States—and inside homes—are carpenter ants, odorous house ants, pavement ants, and pharaoh ants. Though less common inside houses, you may also see fire ants, especially if you live in the South. To learn more about how to identify each of these ants, check out this article.
It's worth noting that when flying ants appear to be swarming the exterior of your house, they're interested in mating, not getting inside. This happens during certain times of the year when environmental conditions are optimal
Ants live in colonies that can range considerably in size. A small colony might include a few hundred individuals while a large, well-established colony might include several thousand ants. Ants typically establish colonies underground or inside trees; however, they can also establish them within the walls of homes or behind baseboards. Each colony will have its queen as well as ants that perform specific tasks that depend on their station. Ants can be a nuisance at any time of year, but they are especially active in spring, when they come out of their winter hibernation in search of food, and in fall, when they're in search of shelter.
Typically, ants enter your home for those reasons: they're searching for food, shelter, or both. Ants spend their lives foraging for food and water; chances are, if they get inside of your home, they'll discover a veritable jackpot of materials that suit their basic needs for survival. The first ants that enter your home are scouts. If they like what they find, they can return with hundreds more.
One of the most obvious signs of an ant infestation is seeing ants crawling around in areas of your home. Ants typically make their way to the kitchen or pantry in search of food, but it's not uncommon to find them in bathrooms or laundry rooms because they may be attracted to the moisture.
Aside from trails of ants crawling around your counters and walls, you might also see these other signs if you have an infestation:
If you encounter an infestation, it's important to take care of it quickly. Untreated ant infestations can lead to increased colony size, resulting in more damage and food contamination. It can also be incredibly frustrating to try to keep ants out of your food, as they can be quite determined. Here's what you might be looking at if you leave an infestation alone:
Repel ants inside and outside your home. If you've spotted ants on your countertop, use a 50/50 spray of water and white vinegar to wipe down your counters. Not only do ants hate the smell of vinegar, but the vinegar will destroy their scent paths, which temporarily disrupts food-hunting efforts. This won't kill them, of course, but it will buy you a bit of time so you can spray to control them. Other aromatic materials that can help keep ants away include cinnamon, cloves, baby powder, peppermint, coffee grounds, and citrus peels. You can place these materials outside foundation cracks to dissuade ants from venturing inside your house.
Kill the ants already inside your home. When it comes to getting rid of an existing ant infestation, there are several highly effective options. Remember to always read and follow the label directions.
