Ship Rat (Rattusrattus)
Ship rats are medium sized rats that are equally at home on or off the ground. In urban and rural habitats they will frequently be found living in trees, houses and other three dimensional habitats where their ability to climb allows them to escape human disturbance and avoid predators.
In contrast to mice, Rats tend to have only a few feeding sites and the key to successful control is to ensure there is a good quantity of bait available (sub-lethal doses can affect the level of control which will be achieved longer-term). Whole grain bait is the most commonly used, and active ingredients such as Difenacoum and Bromadialone can be used indoors and out. Rat burrows can be baited directly if safe to do so and trapping and use of gassing compounds such as Aluminium Phosphide (professionally trained operators only) can be used.
