Having ants on your property or invading your home stinks. But there is a type of ant species that can make the experience of an ant infestation stink LITERALLY. That is the Odorous House Ant. Odorous House Ants are native to the United States and get their name due to the foul odor they emit when stepped on or crushed which smells similar to that of rotten coconuts.

Odorous House Ants commonly invade homes, hence the “house” being part of it's name. They typically enter homes in large numbers after heavy rains to seek shelter from flooding conditions. They are not known to cause any damage to homes, which may make them go undetected by homeowners for some time before they are discovered.

Odorous House Ants like to forage both day and night and are most attracted to sweet-tasting foods like honeydew from plants, syrups, fruits and other sugary foods. They are often nicknamed “sugar ants” because of their affinity for sweets. When indoors, these ants usually build their nests in wall voids, especially around moist and damp areas such as around water pipes sinks, cupboards and crevices.

If left untreated, Odorous House Ants can get pretty out of control with their invading population. If you have a problem with this type of ant, follow our guide below to learn how to get rid of Odorous House Ants quickly and affordably.

Once you have confirmed that you are dealing with Odorous House Ants, proceed with inspection. During this phase, you will be searching for these areas of your home, where foraging trails develop, or where their colony could possibly be.

Where To Inspect 

Outdoors search in your yard under yard debris, like leaf litter, rocks, logs, woodpiles, bricks, stones, under flower pots, mulched areas, rocks, and general clutter. Indoors you can find them near moisture-prone areas that receive warmth like wall voids near plumbing, near water heaters, under sinks, around toilets, and in the kitchen near appliances.

What To Look For

You're looking for Odorous House Ants, their foraging trails, and their colonies. Inspect all the areas mentioned above and follow their foraging trails back to their nest or the colony or the cracks and crevices in your home where they are emerging from. Once you find these locations this is where you will apply treatment.


Once you have confirmed Odorous House Ants activity it is time to begin treatment. Remember to read all product labels and follow the application instructions on these labels, and stay safe by wearing personal protective equipment (PPE).

Step 1 - Outdoor Treatment with Supreme IT

Supreme IT is a powerful insecticide that targets over 75+ insect pests, and it both repels and kills insects, including Odorous House Ants. It also has a great residual (or long-term effects) that will last up to 90 days.

To do a perimeter treatment using Supreme IT mix 1 oz. of Supreme IT with a gallon of water inside a pump sprayer. This application rate will treat 1,000 square feet. To do the perimeter or barrier treatment, spray 3 feet up and 3 feet out from the foundation of your property. While also targeting windows, door frames, eaves, soffits, rain gutters, in electrical/plumbing penetrations, and in cracks and crevices, where Ants might enter.

Next, follow label applications and do broadcast treatment (broadcast meaning all over your yard). Start the back of the lawn, and make your way to front spraying the whole lawn. While spraying in this manner also spray in patios, in ornamentals, in mulch beds, around yard debris, and near yard structure like tool sheds, and gazebos. 

Do not let people or pets enter areas treated until 2 to 4 hours have passed.

Step 2 - Indoor Treatment with D-Fense Dust

Applying D-Fense Dust to treat Odorous House Ants

If you have an Odorous Ant infestation indoors, apply D-Fense Dust. D-Fense Dust is perfect to apply in cracks and crevices where the ants are emerging from, and it is also moisture resistant which makes it perfect to apply in areas like where water heaters are located. 

To use D-Fense Dust you will need a handheld duster. Fill the duster halfway with D-Fense Dust and leave plenty of room inside the duster for air to circulate inside. Apply this product by squeezing the duster. Apply in cracks and crevices in the home, like under sinks (where plumbing penetrates walls), along baseboards, and in any crack and crevice you're able to find and where you have noticed Odorous Ants emerging from.

Step 3 - Ant-Trax Ant Bait

ant-trax ant bait how to get rid of odorous house ants

Ant-Trax Ant Bait is a bait that mimics sweets and that the ants will come in contact with and carry back to the nest. Because it works slowly this product will target every ant that comes in contact with it, and once it is carried back to the nest, it will affect the whole colony.

Ant-Trax is easy to use and comes in a syringe. To apply simple press down on the plunger. Apply a pea-sized drop where there is ant activity. Separate each placement by at least one foot. Apply in countertops, in kitchens, in bathrooms, near appliances, near baseboards, and in entry points (like cracks and crevices near window frames, and door frames).

When using this product let the ants create foraging trails and do not kill the ants that come in contact with the product. Also, do not use cleaning supplies or other insecticides where Ant-Trax has been applied. The point is the let the ants came in contact with the product, and to allow them to carry it back to the nest. Allow for 7 to 10 days to go by and let the ants consume as much bait as possible.
