Carpenter ants: locate the main nest, eliminate the colony at the source.

The carpenter ant is often associated with a "wood-eating" species. In reality, the carpenter ant is not xylophagous: it does not feed on wood. It excavates rotten or damp wood (the gruges) to build its galleries and establish its nest.

We conduct a thorough inspection of your home to identify the main and satellite nests as well as the entry points.

Identification of the nests

Our goal is to identify where the main nest and the satellite nests are located. This step is crucial: treating it "blindly" often leads to temporary and ineffective results.

Targeted treatment with biopesticides

We prioritize treatment with biopesticide baits that target the colony and the queen, applied strategically to achieve a gradual reduction and then a complete disappearance of activity.

The treatment is maintained and adjusted with follow-ups until a zero presence is achieved (no activity observed), with an approach focused on measurable results on the ground.
