With a healthy colony containing as many as 100,000 workers, you need to be sure you deal with the infestation properly the very first time. Otherwise, you may find yourself with two or more colonies budding from the original. Some sources advise against using baits inside because that can draw more ants into your home. However, if you have an infestation in the fall when it is cooler, you would be well advised to use indoor ant baits. Odorous house ants like to eat sweets and are especially fond of honeydew. They are known to move their nests every three months or so in response to rain.
Argentine Ant (Linepithema humile)
Argentine ants will readily share food and nesting spaces between separate colonies. Their lack of aggression toward each other gives them an advantage over other ant species when competing for resources. While this resolves the immediate issue, it does not address hidden eggs and nymphs. Do-it-yourself insecticide treatments can be used both inside and out, but if not administered properly, they have the potential to drive earwigs into untreated areas in your home.
Control
Baits are usually the best option for eliminating ants that have entered the home. Following all label directions, the bait should be placed where ants have been seen. Because ants can be finicky and prefer different types of foods at different times of the year, you may need to try different baits. The ants will feed on the bait, then carry it back to the nest to feed the colony. It is through this feeding that the insecticide will be transferred to the queen and other colony members to kill them.
Remove pests from your home, and stop them from coming back
Odorous house ants live in colonies ranging in size from hundreds of workers and one queen to thousands of workers with hundreds of queens. The queens of an odorous house ant colony are capable of producing thousands of workers and hundreds of reproductive ants. When the honeydew supply is reduced in autumn, they may move indoors for food. Indoors, they eat meats, sugary foods, dairy products, pastries, cooked or raw vegetables and fruit juices. Odorous house ants, as their name suggests, emit a distinctive odor when they are crushed or threatened. Specifically, this odor is often described as smelling like rotten coconut, blue cheese, or sometimes even a sweet, fruity scent.

Carpenter ants (Camponotus spp.) – The black carpenter ant becomes a problem for Inland Empire homeowners when there is wet, decaying wood around their property. This can encourage an infestation of your home and eventually result in major damage to your home’s structure. Southern California is home to only a small percentage of the over 12,000 species of ants that exist around the world.
When to Call a Professional To Treat an Odorous Ant Infestation
Erasing these trails prevents new ants from gathering in your home. A good DIY spray is a mix of 50/50 white vinegar and water in a spray bottle, shake, and spray it on ant trails and nearby spots where you saw the ants trailing. Odorous house ants can develop extremely large colonies but tend to maintain colonies of only several thousand workers with many queens. They mostly prefer sweets but will also feed on dead insects and grease. Nests are typically found outside under rocks, boards and the like, but can also nest within structures. Colonies are from hundreds to many thousands of individuals in size.

The odorous house ant is native to most of the entire United States ranging from Canada into Mexico. These ants feed on many different items including most items found in homes but apparently prefer to feed on those high in sugars. Outside, Tapinoma sessile will feed on honeydew excreted by aphids and on nectar from flowers and buds. The first is when the colony produces winged male and female reproductives who swarm out of the nest, mate and the fertilized female establishes the new colony. The second way odorous ants form new colonies is when a queen and workers bud off from the main colony and form their own new colony. Outdoors, odorous house ants place their shallow nests beneath soil as well as in logs, mulch, debris and under rocks.
Odorous house ants can be very annoying as they frequently establish trails along kitchen counters, cabinets, sinks, and baseboards in their search for food. But, not knowing what rotten coconut smelled like, he had no idea what that meant. And, since he went to grad school in the arid Southwest (where T. sessile are rare), he had no chance to find out. Inspect your walls for cracks, crevices, or gaps that the ants could use as entry and exit points. Common locations for nests include wall voids, behind baseboards, under sinks, bathtubs, and around electrical outlets.

This ant gets its name from the strong, rotten coconut-like smell it gives off when crushed. These tiny insects range in size from one-sixteenth of an inch to one-eighth of an inch long, and they can live for many years. These ants live in large colonies, which can range anywhere in size from 100 to more than 100,000 workers.
Make sure that there are no cracks or little openings around the bottom of the foundation. Ensure firewood and building materials are not stored next to the home because odorous house ants like to build nests in stacks of wood. Argentine ants thrive in urban areas and are attracted to food and water sources. Argentine ants can be a nuisance pest when they enter structures.

It’s possible that odorous house ant is really four similar-looking species, but until more data are produced to support this hypothesis, we’ll consider it as one. In 2009, it was discovered on the island of Maui, Hawaii and is now characterized as an invasive species. The most obvious sign that you have odorous ants is their distinct smell. They usually travel in lines, but if they are disturbed or alarmed they will run around erratically, releasing their odor as they run. Some people have also equated their odor with a sort of strange pine scent, though rotten coconuts are the most frequent association.
True to their name, odorous ants release an unpleasant smell when crushed. When they invade kitchen storage areas, the pests have a tendency to contaminate food products. These ants are able to bite, but they do not cause much pain. Odorous house ants are recognized as being one of the most commonly encountered ants inside homes. While odorous house ants do not sting or bite, they can become persistent pests, traveling indoors in large numbers.
In most situations, it is recommended that you wear long pants, a long sleeved shirt, closed toe shoes with socks, chemical resistant gloves, and goggles. In areas where ventilation is poor, a manufacturer may recommend you wear a mask or a respirator. We have put together two different safety kits that will make selecting the correct safety gear easier for you. Ants can arrive without warning and cause several problems both in and around your home. These pests are small, fast, and breed quickly, making them a challenge to locate and difficult to control. Moreover, the odor can vary slightly among individuals and colonies but is generally recognizable as pungent and unpleasant.
Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. We teach, learn, lead and serve, connecting people with the University of Wisconsin, and engaging with them in transforming lives and communities.
To prevent the creation of odorous house ant nests, store firewood and other building materials as far away from your home as possible. It is critical to survey inside and outside to locate all nests. Nests found outside can be drenched with a residual insecticide. Baits that have a protein or sugar-based attractant may be effective when the nest is not accessible. A pest control operator can be hired to complete the treatments described. Monthly treatment for a year or more should not be necessary for control.
