As their name indicates, Pavement Ants can usually be found in cracks in the pavement, along walkways, and under stones, as well as behind walls and under floors. These pests are a particular problem for homes with slab on grade construction. Pavements Ants search for food in and around homes all year long and prefer greasy or sweet foods, but aren’t all that picky when it comes to a meal.
Pavement Ants coloring ranges from light brown to black, with legs lighter than their bodies and 12-segment antennae. Pavement Ants also have unique markings – parallel lines on their head and thorax. These ants measure about 1/10 of an inch long.
The Pavement Ant queen lays 5 to 20 eggs each day, which develop in about 40 days and evolve through three larval stages before reaching maturity.
