However, problems occur as it is such an effective killer. It kills all air breathing species that consume the product. New Zealand is the largest user of biodegradable 1080 poison, using about 80% of the world 's supply.
1080 is considered to be suitable for use as a mammalian pest control in New Zealand as the country has only two native land mammals (bats). When correctly applied, 1080 is very effective at controlling Conservation Land pests. One aerial application can kill 98% of possums and more than 90% of rats in the targeted area. These successful kill percentages provide vulnerable native birds with a crucial breeding window to raise chicks through to fledging, increasing their survival rate. The DOC uses aerially applied 1080 poison across about 440,000 ha of conservation land each year. Both aerial and ground-based application of 1080 poison is also used to control rabbits.
