Pavement Ant Habits
These ants are named after their nesting tendencies: they prefer to nest around asphalt, patios, and sidewalks. They will also nest under large stones or under dead trees. Pavement ants are very common throughout the US, and their nesting sites are easily recognized. When they dig out dirt for tunnels and nesting, they create mounds at the entry point. Colonies of pavement ants can reach up to 10,000 members.
When a colony reaches capacity, they will send out new ant queens to build other nests. These future queens have wings, as do the male drones who will mate with them. This swarming typically happens in spring. If a nest is not treated, the pavement ants will continue to spread year after year.
Pavement ants will feed on anything, including fat and grease, sugar substances, and other foods. They will scavenge for any kind of edible crumb, and will invade buildings to find food resources for their substantial colonies. They are also notorious for interrupting picnics and outdoor spaces.
Preventing and Eliminating Pavement Ants
Because pavement ants are so common, most people leave them alone. This can be a mistake, as pavement ants will continue to spread across sidewalks and surrounding areas.
The goal with pavement ants, as with most ant species, is to kill the entire nest to eliminate them permanently. If you’re seeing ants but don’t know what species they are, or where their nest is, eliminating the nest (and the ant problem) can prove to be very difficult.
Calling an expert ant exterminator is the best way to completely eliminate pavement ants.
