Rodents in Australia

Rats and Mice are one of the most common and dreaded pests in Australia today. Not only do they cause economic loss through damage on farms and in commercial premises, they also carry disease and can be harmful to your home and families health.

The breaking of the drought has brought with it flooding rains and bumper crops. This provides the perfect food and board for the common mouse. Mouse numbers grew strongly throughout southern Queensland, New South Wales, western Victoria and South Australia during the first half of 2011. While these went underground after Winter, similar conditions in 2012 could see them return in plague proportions.

The most common rodent characteristic are their front incisor teeth, which continually grow. Without grooming, rat's incisor teeth can grow up to 10cm in 1 year. Gnawing and chewing on soft surface such as wood, aluminium siding, wallboard, plaster, paneling and concrete are part of their grooming process. This is why you'll often see chewing marks on surfaces.

Rodents are resilient pests, and will adapt and thrive in almost any environment: While populations can fluctuate depending on the season, they are an all year round pest!

Rats are most active in wet weather. They lose and need to replenish water when they are active. They’ll often remain in a location until the water source runs out. Being very social animals, if you see evidence of 1 there’ll be 10 in the same vicinity.

Mice can remain active in dry weather and will survive long periods, even in dry climates. They draw moisture from their food which can last them for long periods of time.

When identifying which rodent control product is suitable for your pest problem, it's important that you consider where the rodent pest is nesting or entering the area. They are rarely just in one place.
