As the long Perth summer fades and the chill of winter sets in, your roof void transforms into a five-star resort for rodents. It’s warm, dry, full of soft insulation for nesting, and safely elevated away from common predators like cats and foxes.

Before you hear the dreaded scratching above your bedroom ceiling, here is precisely what you need to do to secure your roof against mice and roof rats.

A common DIY mistake is throwing a handful of supermarket bait blocks into the manhole and hoping for the best. This often results in a mouse dying in an inaccessible corner of your wall cavity, creating a terrible odor that lasts for weeks.

A professional rodent eradication strategy involves placing secure bait stations strategically along the actual runways that rodents use, combined with a comprehensive exclusion plan.
