Pavement ant: Quick management tips

Overall strategy

Focus efforts on keeping ants out of the house. Follow good sanitation practices to make your home less attractive to ants. Spraying ants inside the home will not prevent more ants from entering. Use baits to control the ant colony.

When ants invade your home take immediate action

Sponge invaders with soapy water as soon as you see them.
Plug up ant entryways with caulk or petroleum jelly.
Remove infested potted plants.
Clean up food sources such as sugary spills, pet food, or garbage.
Rely on baits to control the ant colony.
Indoor sprays are not usually necessary.

Prevention

Focus efforts on following good sanitation practices and excluding ants from buildings.
Keep ants off of trees or shrubs near buildings.
Be prepared for annual invasions by caulking and baiting before the influx.
