Rodents are a significant threat to flora and fauna in New Zealand. As omnivores, rats will eat anything from birds, chicks and eggs to lizards, fruit and flowers. As good climbers, they can also access bird nests high in the trees. Found throughout New Zealand, they compete directly with native wildlife for food.

Mice are not only a nuisance but they also carry diseases. Both rats and mice can do major damage around the house including damaging electrical cabling, which could result in a fire.

Both field mice and house mice are common throughout New Zealand. Mice tend to stay outside during the warmer months, seeking refuge inside during the colder months.

Rats and mice can both be controlled by trapping and/or baiting. We place all of our bait inside pet-proof anti-tamper bait stations, so that your pets cannot gain access to it.

You can help keep rats and mice away from your property by keeping the inside and outside of your home free from food scraps (including pet food). Store rubbish in secure containers with lids and do not leave rubbish bags out overnight.

Tidy up overgrown grass/weeds, rubbish etc and secure any gaps or cracks in your home so that rodents can’t gain access.
