A minor issue in one room is cheaper to treat than a widespread infestation that requires multiple visits. We also consider the location of the pests and the products needed to handle them safely.

About this service

Carpenter ants hollow out wood to build nests, which can weaken your home's framing over time. We locate the main nest and satellite colonies to stop the activity. Call us if you see large black ants inside or find piles of sawdust-like frass near walls or doors. Removing them early prevents costly structural repairs.

Summer heat creates the perfect environment for pest populations to explode. Common summer pests like wasps, mosquitoes, and roaches are at their most active point of the year. Keeping your home protected during these months is essential to enjoy your space comfortably. If you notice an increase in bug sightings, reach out to get a professional assessment.
