Pavement ants are one of the most common home invaders in North Carolina. As soon as these pests see an opening, they travel in swarms into your property and invade any food or sweets they can get their hands on. While not dangerous, these pests represent a substantial hassle, and are one of the most common pests.

LIFE CYCLE OF PAVEMENT ANTS

Another colony of ants creates a new queen. That queen then starts laying eggs. These eggs are pin sized, off-white, and shaped like puffed rice. The eggs hatch and to become pupae, which are fed until they grow a stronger outer shell. Then they become mature pavement ants, and play a role in colony survival.

PAVEMENT ANTS AS PESTS

Pavement ants send foragers out to look for areas that might have food. You may see one or two ants in your home at different times all throughout the year, even if you do not see an invasion.


If pavement ants find food, they’ll return back to their colony and send a message to other ants that food is present. That’s when the invasion will begin. Thousands of ants converge upon the food, while dozens more continue to scour the nearby area looking for more treats. When/if they find them, more ants will come to scavenge those new finds. Your entire kitchen may quickly become a meal.

HOW TO PREVENT PAVEMENT ANT INVASIONS

Preventive pest control is the simplest way to prevent pavement ant invasions. You should also seal up any known holes or possible entranceways using a process known as exclusion. If ants cannot get in and out of your home, they will not be able to find food.


You should also seal up any containers of food, especially those with sugar and starches, and clean up after any spills, scraps, and trash. Dog food should be taken off the ground when not being eaten as well. Ants are not known to invade refrigerators or freezers, so those foods may be safe.
