Ant treatment

A few ants crossing the kitchen are manageable. But an established colony produces thousands of workers, and carpenter ants can hollow out structural wood. Pharaoh ants sometimes infest hospitals.

A few ants crossing the kitchen are manageable. But an established colony produces thousands of workers, and carpenter ants can hollow out structural wood. Pharaoh ants sometimes infest hospitals.

Our treatment targets the queen and the colony, not just the visible workers. Without that, the columns return within days.

How to spot the problem

The signs to identify

Worker trails

Regular lines along skirting boards, on worktops, in cupboards. Visible entry point (crack, socket, threshold).

Fine sawdust near wood

Carpenter ants: very fine sawdust near beams, frames or wooden decking.

Winged ants in spring

Reproductive swarming: winged ants indoors = colony installed nearby.

Why act fast

The risks of leaving an infestation untreated

Food contamination

Ants travel from unsanitary places to preparation areas. Watch in kitchens, bakeries, nurseries.

Structural damage

Carpenter ants: long-term tunneling in wood, weakening of beams and frames.

Methodology

Colony-effect treatment

Killing visible workers is pointless. The queen must be reached. Our insect gel is carried by the workers back to the heart of the nest.

  1. 1

    Trail and nest mapping

    We follow the trails to the entry point and, where possible, locate the anthill.

  2. 2

    Targeted gel or powder

    Baited gel for indoor ants, barrier powder or injection for carpenter ants and outdoor colonies.

  3. 3

    Preventive access treatment

    Cracks, thresholds, inspection chambers: sealed and treated to prevent recolonisation.

  4. 4

    3-week check

    Verification of total inactivity. Free re-intervention if required during the guarantee period.

« Cockroaches in the kitchen of an old building. Gel treatment, nothing for 6 months. The team also treated the communal areas at no extra cost — very honest. »

Frequently asked questions

Can I use white vinegar against ants?
It masks the chemical trail for a day, no more. Without reaching the colony, ants come back as soon as the trail is erased.
How long until I'm clear?
The gel works in 2 to 3 weeks, the time for workers to contaminate the queen. We return to check on schedule.
