Ant Control in Yakima & Kittitas County

Ants, they range from Carpenter Ants, Pavement Ants, Odorous Ants (sugar) to Moisture ants. No matter the kind they can be really persistent, making control challenging, most ants should be treated professionally and can have adverse behavior if “over the counter” products are used. Some things you can do to reduce the risk of ants infesting are:

  • Keep kitchen clean & free of food spills

  • Clean counters regularly

  • Keep areas around trash can clean

  • Trim all vegetation away from house at least 12”-18”

  • Keep exterior garbage receptacle clean

Structural Damage

Wood destroying ants like carpenter ants and moisture ants are capable of causing damage without your knowledge. When the ants are finally noticed the colony has been thrive for a long time, our total protection plan SiteCare Plus will give you warranty on these and more.

Ants can be a major pest for homes and businesses in the greater Kittitas County area and we at Prosite Pest Control understand how important effective ant control can be. Left unaddressed, an ant infestation can result in expensive repair bills and an unattractive living space. Home remedies and over the counter pesticides cannot effectively remove an ant infestation in the way our trained pest control experts can.

Why Do I Have Ant Problems?

Generally, ant infestations enter a home in search of food or nest space. For most homes, carpenter ants can post the greatest threat, since they bore passages into the wood in order to build a nest for their young. Left unaddressed, a carpenter ant infestation can result in thousands of dollars worth of structural damage to a home or business.

In addition, a number of ant species will enter a home in search of sweets or other foods. These pests can ruin food, get into bedding and otherwise damage the living conditions of the home. These types of ant infestations can be especially inconvenient for homes with children or pets.

Long Lasting Ant Control

Eliminating an ant infestation requires the destruction of the nest. Simply spraying those ants that are in the open does nothing to eliminate the root of the problem. We can ensure that the source of the problem is eliminated, rather than simply addressing the visible symptoms. This is especially important when dealing with carpenter ants, since the only way to eliminate the nest and prevent further damage to home is to locate, treat and replace the infested wood.

Finally, our treatments also ensure that future infestations will be prevented. By determining what parts of the home might be vulnerable in the future, we can help develop a treatment plan that prevents later ant infestations from becoming established in the home. This helps ensure that you and your family will be able to enjoy an ant-free house long after we have eliminated the current infestation.

At Prosite, we can help you protect your home from current and future infestations alike. Call us today to speak with one of our skilled pest control specialists and obtain a free consultation and quote.

Common Ant Infestations

Carpenter Ants

Carpenter Ants

Carpenter ants are common sights in the Americas, Europe and other parts of the world. Because carpenter ants cause damage to wooden areas where they nest, their presence can be mistaken for a termite infestation. However, while termites eat wood, carpenter ants merely make galleries in wooden areas for shelter.

All species of carpenter ants prefer decayed wood for their nesting sites, as these areas provide proper and consistent humidity and temperatures. Although carpenter ants do not eat wood, damage can be severe when nests remain active for several years. Over time, a colony can expand into several satellite colonies near the parent colony. Workers excavate wood for extra space, causing extensive damage to structures and woodwork.


There are 24 pest species of carpenter ants in the United States alone. For this reason, carpenter ant identification can be difficult. Size and color of carpenter ants can vary among species and even among individuals within one colony. Carpenter ants measure from 3.4 to 13 mm in length and can feature black, red, brown, yellow, orange, or red and black coloration. Although carpenter ants are among the largest ant species worldwide, size is not a reliable factor in carpenter ant identification because workers within a species vary in size.

Carpenter ants are often mistaken for termite swarmers, particularly during swarms when winged male and female ants fly out of their colony to mate. The most important characteristics to look for when identifying any winged ant are elbowed antennae, a pinched or constricted waist and a front pair of wings that is longer than the back pair. Termite swarmers will have straight antennae, a broad waist and both pair of wings similar in length.

Carpenter ants develop by complete metamorphosis: from eggs to larvae to pupae to adults. Adult carpenter ants have six legs, a constricted waist, three distinct body regions and a ring of hairs at the tip of the abdomen (best seen under magnification.)

Locating the Nest

Locating carpenter ant nests can be accomplished by following the trails of the worker ants themselves. Search for a clean and smooth cavity in the infested area, as well as slit-like windows in the surface of the damaged wood. Small piles of wood shavings can often be found below the openings. After identifying a colony, it is advisable to contact a pest control professional, as several satellite colonies may exist elsewhere within or around the home or building.


Odorous House Ants

Odorous House Ants

Odorous house ants are opportunists, nesting both indoors and outdoors. Indoors, odorous ants can nest in wall crevices, near heaters, water pipes, under carpets, beneath floors or sometimes behind paneling. Outdoors, odorous house ants place their shallow nests beneath soil as well as in logs, mulch, debris and under rocks.

Like all ants, odorous house ants live in colonies. Each colony may contain two or more queens and over 100,000 workers. The queens of an odorous ant colony can produce thousands of workers and hundreds of reproductives. Odorous house ants forage for food night and day. Outdoors they prefer honeydew from aphids and mealybugs. 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, sometimes called odorous ants, are small, measuring 2.4 to 3.3 mm in length. They have dark brown or black bodies with one node on their petiole, which is hidden by their abdomens. Odorous house ants have an unevenly shaped thorax when viewed from the side. The most distinguishable characteristic of odorous house ants is the smell of rotten coconut that is emitted when their bodies are crushed. The most likely sign of odorous house ants is the foraging worker ants, although winged swarmers also might be observed.

Biology and Habits

New colonies are created in two possible ways. 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. Swarming typically occurs in the summer months. 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.

Odorous ants develop by complete metamorphosis from egg, larva and pupa to adult. Development time from egg to adult is affected by several variables, such as temperature, but typically ranges from 34 to 83 days. Because odorous house ants tend to forage inside homes, they can easily contaminate human food supplies. While odorous house ants do not sting or bite, they can become persistent pests, traveling indoors in large numbers.


Pavement Ants

Pavement Ants

Pavement ants measure approximately 2.5 to 3 mm in length and have brown to black bodies, pale legs and antennae. These ants are found throughout the United States and are major pests in the Midwest. Pavement ants earned their name because they nest in cracks in driveways and under sidewalks, piling the resulting dirt in a mound on top of the pavement. A typical colony of pavement ants includes multiple queens and numerous workers. A queen establishes a new colony of pavement ants by laying eggs. Pavement worker ants then tend the queen’s brood until they develop into adults. During their development, broods are transferred from location to location to protect them from fluctuations in moisture and temperature.


Pavement ants are light brown to black with appendages lighter than rest of the body. They are about 2.5 to 3 mm long, with parallel lines on head and thorax. They have 12-segmented antennae with a three-segmented club. Worker pavement ants are the most likely sign of an infestation, but other indicators can be small piles of excavated materials or even the swarmers.

Biology and Habits

Pavement ants invade buildings while foraging for food. Nests are outdoors under stones, along curbs or in cracks of pavement. They can nest indoors in walls and under floors. Pavement ants will feed on a wide variety of foods, including meats, grease, live and dead insects, seeds and honeydew from aphids. They prefer to eat greasy foods, and can eat many foods consumed by humans. They forage for food for their colonies and set up trails to food sources from their nests. Pavement ant workers enter houses to forage and can become a nuisance when large groups infest a kitchen or garden patio. They can sting and bite. Reproduction occurs when winged males and females swarm, often in June and July. After mating, the females search out a new nesting site and become the queen for a new colony.
