This design of bait station was made for Connovation Ltd in East Tamaki, Auckland. They are designed for possums. Each cavity has a cyanide pellet covered with a flavoured paste lure, so one tag can effectively eradicate three possums. The tag has a warning label stuck to the back and is then stapled to a tree away from ground feeders.
Being made out of potato starch and cellulose, the tags will biodegrade away if they have not been devoured by the possums.
