Action Threshold: Presence of adults may not be a good indicator of an infestation because ants are known to forage quite widely.
Management: Chemical controls are usually the best option for a carpenter ant infestation inside a building when the nest can be located.
Queens are large and black with some red, brown, or yellow spots occurring on parts of the body and legs. If piles of sawdust are found in an area of high ant activity, it is likely that the ants are nesting close by.
Carpenter ants do not eat wood but they often nest in moist wood, including rotting trees, tree roots, tree stumps, and logs or boards lying on or buried in the ground. The ants may cause damage to structures when they nest in or hollow out wood boards for shelter. Carpenters, weavers, gardeners, harvesters, drivers, and honeypot ants all uphold the image of the hard-working cooperative society.
The ant realm is endlessly fascinating, as the plethora of books and nature programs on the subject attests. When ants invade our homes, however, our admiration ceases, and we quickly perceive them to be pests.
While few of us welcome ants as houseguests, in the garden most ant species are beneficial.
There are probably tens of thousands of ants in the average West Coast landscape, mostly functioning as scavengers.In gardens, pest ants are usually those feeding on honeydew, produced by homopteran pests such as aphids and mealybugs.
On plants such as citrus, ants and homopterans are a problem, but in many cases, the role of ants is not easily determined.

For instance, some ant species that are principally beneficial sometimes supplement their diet with honeydew when other resources are scarce. Some ants that are pests in houses, such as carpenter ants, provide a service in the landscape, where they help break down dead wood. Observation is the key to determining whether ants are behaving as pests or benefactors in the garden.Ants are far more diverse than many of us realize. Honeypot ants, for instance, live in many arid and semi-arid areas, but most people have never seen them, since the unusual workers, their bellies full of nectar, are found underground.One observer described an ant colony as a factory inside a fortress. Ants are highly evolved social insects; duties are divided among castes of adults, which typically include reproductive queens, sterile female workers (sometimes of several different castes, each with its assigned task), and short-lived males (whose only role is reproduction).
The nuptial flight is the poetic name for the mating that occurs when the winged females and males emerge from the nest. Unlike bees, some ant species have multiple queens, which may explain the difficulty in eliminating colonies.
Ant colonies have a complex system of communication, mediated by pheromones (chemicals) that they exude.
Many ants are scavengers; depending upon the species, they may also feed on plants, invertebrates, fungi, or a combination of these.
In the Pacific Northwest, a mutualism exists in some fruit trees, such as peaches and cherries, that have extra-floral nectaries supporting ants.It is well known among gardeners that ants protect aphids from many of their natural enemies. Yet, some of the most useful ants, from a biological control perspective, are species that use honeydew as a resource when other food sources are scarce.
This poses a dilemma for the gardener who would prefer to not have mealybugs, ants, or the sooty mold that accompanies them in their citrus!

It may be wise to tolerate a few aphids elsewhere in the garden, as they will be an alternative food source for many valuable garden predators, in addition to ants. The Chinese introduced weaver ants to the citrus orchards to protect the trees from herbivores, a technique also in use in the Mekong Delta of Vietnam. Studies on biological control by ants have also been conducted in coconut and cacao plantations. California gray ants are known to prey on peach twig borer.When ants behave as garden pests, management may require a combination of methods. Do all you can to prevent the arrival of Argentine ants, as it will be impossible to eliminate them once they have invaded your garden.
Check all potted plants for ant colonies before bringing them home; this is especially important in Oregon and north, where Argentine ants are not currently a problem.
Concentrate control efforts in the late winter and early spring, when they will have the greatest effect.Above all, I try to follow the advice, perhaps apocryphal, of biologist EO Wilson of Harvard, who has devoted his life to the study of ants. Outdoor baits will sometimes effectively draw ants out of homes; conversely, placing bait indoors may draw ants into the house. A mere milligram of trail-marking pheromone of leafcutter ants could take a colony three times around the world.
