Thread: The Oldies possum trapping again

I have recently got involved in pest control at Puketoki Reserve - a 100 acre block of bush that is surrounded by farmland - the team have around 70 possum traps and rat cafes - the traps are Warriors and Possum Masters - the Possum Masters are blue - but a few recently delivered are black - the supplier says possums are color blind so black is as good as any other color - so that stuffs up my theories about putting a blaze of flour and icing sugar up the tree - I understood that white was an attractant and they liked the look and smell of flour and icing sugar
Another local group at the Blade in the Kaimais are running large numbers of Warrior traps and they are all mounted on a white backing board as an attractant
The team at Puketoki have been doing it for 15 years and still get about 25 possums each year - likely most are invaders from the Kaimais and surrounding farmland - my interest has been to get them into rat trapping rather than just rat poison - the birdlife is pretty amazing with Black Robins and Kereru being the stars
Any thoughts on possums being color blind, whether white is an attractant and whether a Possum Master is better to be blue or black?
