More about mosquitoes in the Nelson Marlborough region
- New Zealand has 12 native mosquito species and three well-established introduced species.
- New Zealand is an appealing environment for exotic mosquitoes and, once established, they are difficult and expensive to eradicate.
- Nelson and Marlborough have busy seaports (entry points for mosquitoes that may travel in cargo), and mosquito-friendly habitats.
Rats pose a risk to public health for a number of reasons. Their fleas are capable of transmitting plague, and the rats themselves can spread diseases such as typhus, leptospirosis and many more through their urine, faeces and bites.
