Conditions vary across the state. Choose your city below, then describe what’s happening around your home or business.

Look for the rooms and outdoor areas where you regularly notice ants. Food, water, and small openings are useful things to mention when asking for help.

A useful next step

Ask about an inspection, what treatment would involve, and whether follow-up visits are included. You don’t need to know the ant species before getting in touch.
