Pest NameDescription 
Moisture antsMoisture antsMoisture ants are small ants (about 2/16 – 3/16 in length as workers). Color varies, but light yellowish-brown is the most common. They are largely nuisance pests in that they find their way into kitchens and feed on sweet materials including honeydew from aphids. They nest in damp rotting wood or in the soil. They do not nest in dry sound wood. They are actually an indicator of a prior problem, for example, wood-soil contact which sets up the ideal habitat for nesting. Mating swarms occur in late summer to early fall.
