Rat extermination on the North Shore
At a glance: Larger and more wary than mice, rats dig burrows, gnaw on structures and wires, and contaminate food. They enter through openings of about 2 cm. To get rid of them: cut off food and water, block the accesses (steel wool and mortar) and trap with sturdy traps. An infestation requires an exterminator — Exterminateur Rive-Nord intervenes with warranty.
Rats are tenacious — not amateurs
Suspicious and prolific, they are more difficult to dislodge than mice. Professional intervention prevents the infestation from setting in.

Recognizing a rat infestation
Dark, elongated droppings (larger than those of mice), nibbling marks, noises in the walls and attic, traces of grease along the walls and sometimes burrows near the foundation. Spotting a rat during the day often signals a large population.

Why call an exterminator
Rats are wary and return through the same attacks. A professional locates them, treats effectively and guarantees that they are not re-infected. If you hear noise in the partitions, see also our article on rodents in the wall.

Seal garbage cans, store food, fix leaks, keep wood and compost away from the house, and seal access (pest-resistant caulking).
