Controlling rats around your home
The similarities between what DOC is doing on a national scale and what people might do in their gardens is very similar. These guidelines are for ongoing rat control rather than a swift eradication.
Set goals – such as more native birds in gardens and less home-grown produce being eaten.
Co-ordinate and monitor traps. One trap or bait station per acre may well be sufficient if checked regularly.
Report numbers of rats killed or caught to group/network and add up to then assess numbers within a given area. This will then tell you how well you are making inroads to a population. Expect about 4 to 7 rats to be the average population per acre.
Regularly change methods. Swap bait every six months or change from baits to traps.
