Rat & Mouse Control in Perth — How to Deal with Rodents

Rodent activity increases significantly in Perth during autumn and winter as rats and mice seek warmth and shelter. Signs of a rodent problem — droppings, gnawing damage, and noises in walls or ceilings — should be addressed promptly, as rodents breed quickly and can cause significant damage to wiring, insulation, and stored food.

Common Rodent Species in Perth

The roof rat (Rattus rattus) is the most common rodent pest in Perth homes. Despite its name, the roof rat is an excellent climber and is often heard running in ceiling cavities. The Norway rat (Rattus norvegicus) is larger, a poor climber, and tends to burrow — more commonly found at ground level, in drains, and in commercial settings. House mice (Mus musculus) are smaller, highly adaptable, and can fit through gaps as small as 6mm.

Professional Rodent Treatment

A professional rodent treatment involves placing professional-grade rodenticide baits in tamper-resistant stations in affected areas. For roof rats, bait stations are typically placed in the roof cavity and in external harbourage areas. The technician will also identify entry points and recommend sealing works. Follow-up visits to check bait take-up and remove dead rodents are usually included.

Proofing Your Home Against Rodents

The most effective long-term prevention is making entry impossible. Seal gaps around pipes where they enter the home, particularly under sinks and in laundries. Check for gaps in roof eaves, particularly where tiles meet fascia boards or where AC pipes penetrate the ceiling. Trim tree branches that overhang the roof — roof rats use these as highways. Store pet food in sealed containers and clear garden debris that provides harborage.
