Rat Extermination

Heavy noises under the floor. Droppings much larger than a mouse's. A chewed plumbing pipe. Teeth marks on wood, concrete — even metal.

A rat isn't a big mouse. It's an intelligent, cautious and destructive animal that colonizes basements, wall cavities, sewers and hard-to-reach areas. One rat spotted usually means 5 to 20 more. And they don't get caught easily — poorly placed traps make them even more wary.

Why rats are the hardest pest to eliminate

The Norway rat — the dominant species in our region — is neophobic: it instinctively avoids anything new in its environment. A poorly placed trap or a wrong bait makes it suspicious for weeks. That's why amateur attempts often make the problem worse.

Species and behaviour

  • The damage Rats chew through wood, plastic, soft concrete and even aluminum. They damage plumbing, electrical wiring, insulation and walls. Their droppings and urine pose serious health risks: leptospirosis, salmonella, hantavirus.

Our multi-phase approach

  1. Thorough inspection

    Identifying travel routes (grease marks, droppings, teeth marks), nests and entry points. Rats always follow the same paths — identifying them is the key.

  2. Baiting strategy

    Secured bait stations strategically placed on identified routes. Professional-grade products that rats can't find at a hardware store. Adjusted based on the colony's response.

  3. Sealing and exclusion

    Rats fit through a 2 cm hole. We seal with rodent-resistant materials (steel, cement, welded mesh). Special attention to pipe entries, sewers and foundations.

  4. Follow-up

    Rats are cautious and the colony adapts. Several weeks of follow-up are needed to confirm elimination and adjust the strategy if required.

Frequently asked questions

  • How do I know if I have rats or mice?

    Rat droppings are larger (15–20 mm vs 5–7 mm for mice). The noises are heavier. The teeth marks are wider and deeper. If unsure, send us a photo of the droppings.

  • How long to eliminate a rat infestation?

    Longer than for mice. The neophobia of rats extends the process. Expect 4–8 weeks with follow-up for a confirmed elimination. It's a matter of patience and strategy.

  • Do over-the-counter poisons work?

    They can kill individuals, but without a comprehensive strategy (correct placement, sealing, follow-up), the colony survives and adapts. Plus, a poisoned rat that dies in a wall creates an unbearable smell for weeks.

  • Do rats come from the sewers?

    That's a common entry point. The Norway rat is an excellent swimmer and can come up through plumbing. We inspect drain access and recommend backflow valves if necessary.
