Introduced predators (rats, mice, possums, feral cats, hedgehogs, stoats, ferrets and weasels) create havoc on lifestyle blocks. They destroy fruit trees, spread diseases, damage equipment and harm native plants and wildlife. They also breed fast: one pregnant rat can result in 400 more rats in just six months. The good news is that effective predator control is really achievable on smaller land holdings. Knowing how is the secret to success and keeping the costs down.
