Managing rodent pests can be challenging. The Ministry of Environment offers advice on managing rodents, keeping them out, and best-control practices.
When baited and set properly, snap traps are effective at killing rodents quickly and humanely.
It is not a good idea to use poison or baits to control rodents. Poisons can accidentally harm pets, wild animals, or even children directly or indirectly (e.g. when a pet or wild animal catches a dying rodent after it has eaten the bait). Poisoned rodents can crawl away and die, and their bodies can be hard to find and result in unpleasant odors.
Health Link BC tells us its best to prevent rodents by
- Eliminating food and water sources: Store solid waste in tightly-closed containers, and make sure bird feeders are away from buildings and seeds don’t spill on the ground
- Eliminating hiding and living places: remove hiding places near buildings like firewood, equipment or dense vegetation
- Pest proofing buildings: block all openings with durable materials or use heavy wire mesh to cover openings that cannot be blocked
