Ants crawling under door crack

Ants are everywhere. And, for the most part, they're beneficial to the natural order of things. But when you experience an ant invasion and their numbers become too large in your yard, garden or home, they can become quite a nuisance. Keep the ant population under control inside and outside your home with these tips and ideas from True Value.

Get Rid of Ants

Controlling ants starts outside because even when they make it into your house, their nests are usually outside, and it's better to get them before they make it indoors. There are a number of ways to get rid of ants even when they've managed to infiltrate your house — but you'll need to go directly to the source. The queen keeps an ant colony running by producing ant after ant. If she is destroyed, the colony soon goes with her. The problem is she usually resides deep in the nest and is difficult to find and eliminate.

Kill Ant Nests

You can usually trace the ants back to their nest by first discovering where they are getting into your home. Check cracks, edges and seams around doors, windows, trim, etc. Follow the trail of ants back to the nest from there, if possible. You might also locate the nest by noting anthills. When you find out where the ants are coming from, there are products available such as Amdro FireStrike Mound Treatment, which is formulated to kill fire ants in particular. These are applied directly to the nest. There are also lawn treatments such as Amdro Quick Kill Lawn and Landscape Insect Killer that can be applied to your grass to keep ants as well as other insects at bay for a season.

Vacuum Ants Up

Ants that are visible above ground or on your kitchen floor, for example, can be removed a few different ways. One simple method indoors is to vacuum them up along with some talcum powder. If you see an ant convoy making its way in or out of your house, sprinkle talcum powder on them and then vacuum. The powder suffocates them inside the vacuum. If you were to just vacuum them up, they could possibly remain alive inside and make their way out after you think they're gone for good.

Poison Ants

There are a number of commercial ant-killing traps, baits and sprays available at your local True Value hardware store. Commercial poisonous baits, such as Raid Double Control Ant Bait and Combat brand baits can kill the queen and colony. These often can be useful if you don't know where the colony is located. Bait is especially effective because scout and worker ants carry it back to their nest, poisoning the rest of the colony. Sprays are less effective at getting rid of a large invasion because you only kill the ants that you attack with the spray; more are likely to show up later if the rest of the ants from the colony can follow the trail of the first ants. If you aren't being infiltrated by the whole colony, a spray such as Ortho Ant & Roach Killer can get rid of the individual ants encroaching on your kitchen.


When using a pesticide, carefully read the label and follow all manufacturer instructions. Use it only as directed.

Keep Ants Out

The two best ways to keep ants out of your house is to seal as many entrances they use as you can, as well as remove the incentive for their invasion by properly sealing food and cleaning up crumbs and other tasty bits that often attract them inside.

Seal Cracks

Seal cracks around doors, windows or anywhere there's a way for them to get in. Use clear silicone caulk on the exterior walls to create an ant-proof seal. To learn how to properly use caulk, see the project How to Caulk a Waterproof & Airtight Seal. You may not be able to fill every crack, but concentrating on areas around windows and doors will definitely give you a leg up on the invaders. Also, try using house perimeter protection such as Ortho Home Defense Max spray or granules. This type of product is applied outside around the base of your home to keep insects away for an extended amount of time.

Store Food in Containers

Keep food items such as cereal, rice, breads, pet food, etc. in airtight containers. This not only keeps ants from getting in, it also helps keep food fresher for longer.


Try keeping pet food dishes in a larger bowl or dish with a bit of water added to the larger dish to create a "moat." This will make it more difficult for ants to get to your pet's food.

Clean Kitchen Surfaces

Keep all kitchen surfaces clean as much as possible. Sweep and mop your kitchen floor regularly to keep dirt, grime and especially crumbs off of the floor. When mopping, use an antibacterial floor cleaner. Remember, ant baits won't work if there are crumbs to distract them and carry back to their nest. Cleaning up also can clear the pheromone trail that worker ants leave for other ants to follow, giving them less of an invitation to try and enter your home. Use a general household antibacterial cleaner to clean tables and counters. Make sure that you do the dishes regularly and keep your sink clean. Ants are attracted to both the food particles on your dirty dishes as well as any standing water in the sink.

That's it! You're now ready to get rid of the ants that made it in and to keep the rest out for good.
