Mouse extermination on the North Shore
At a glance: Mice enter in autumn through openings as small as a dime (6 mm), reproduce very quickly and contaminate surfaces and food with their urine and feces. To get rid of it: block the access to the steel wool and trap. An established or recurring infestation requires an exterminator. Exterminateur Rive-Nord intervenes with a guarantee of non-reinfestation.
One mouse often hides several
When you see a mouse, others are already hiding in the walls. Acting quickly means avoiding a real infestation.
Mouse sheet in brief
| Type | Small rodent (6 to 9 cm without tail) |
| Where it is found | Walls, kitchen, basement, garage |
| Distinguishing sign | Droppings made of grains of rice, noises at night |
| Main risk | Contamination, gnawed wires (fire risk) |
| Recommended Solution | Exclusion (steel wool) and entrapment |
Recognizing the presence of mice
Typical signs include droppings in the shape of grains of rice (3 to 8 mm), scratching noises at night in the walls, teeth marks on food and wires, and the smell of musky urine . Seeing one of them emerges often indicates an already large population.
How to get rid of them
The effective method combines exclusion (plugging 6 mm holes with steel wool and caulk) and trapping (spring swatters baited with peanut butter). For an infestation, professional bait stations are necessary. Our complete guide details the procedure to follow: get rid of mice permanently. The Health Canada and CAA-Quebec fact sheets recommend the same approach.
Why call an exterminator
Mice reproduce quickly and return through the same fits if they are not sealed. A professional locates the entry points, treats efficiently and guarantees non-reinfestation, anywhere on the North Shore.
Preventing mice
Keep a clean kitchen, store food in airtight containers, repair leaks, and seal openings (see our anti-vermin caulk). See also our prevention tips.
