Moisture Ant Control: Protect Your Home
- Name: The common name “moisture ant” generally includes ants with the common name of yellow ants (Acanthomyops) and cornfield ants (Lasius).
- Distribution: Both of these ant groups are found throughout the continental United States.
- Attraction: If a property owner has a moisture problem in the home or business, chances are pretty good they currently have or may have a future moisture ant issue.
Moisture ants have an interesting behavioral trait whereby they collect and carry water from sources such as:
- Dripping faucets
- Toilet bowls
- Water puddles
- Poor drainage areas
They place water on the wood, which in time causes the wood to rot.
Not surprisingly, moisture ants choose to make their nests in and around moist, rotting or decaying wood or underneath rocks. Moisture ants are secretive, and forage for food mostly at night.
Moisture ants do not feed on wood like termites; rather they forage for honeydew and other sweet substances produced by aphid and other insects. In addition, they feed on fungus growing in damp wood.
Some species of moisture ants prey on both living and dead small insects. Where cornfield ant populations are particularly large, they will sometimes move indoors and feed on sweets and other available food debris.
Colonies usually nest in decayed logs, stumps and under rocks, but some may be found living in the soil.
Moisture ants nest in and around foundation walls and soil under buildings on slab construction.
Moisture ants mate during reproductive swarms that usually occur in late summer to early autumn.
However, swarms also may occur indoors in the winter if ants are nesting under heated concrete slabs.
While moisture ants are a nuisance, especially when swarms invade a home or business, they are not considered primary structural pests.
While they may accelerate the deterioration of wood, they are nowhere as destructive as termites or carpenter ants.
While never wise to overlook the presence of moisture ants, your Western Pest Control Specialist can advise you whether or not the infestation justifies the expense of replacing decaying wood or applying pest control products.
Steps to Take
The first step to treat moisture ants is determine whether the ant is a moisture ant or another kind of ant.
The second step is to determine where the ant’s nest(s) are located and where the ants are coming from.
