Chew Cards - Peanut - High Density
Excluding GST. Shipping calculated at checkout
Chew-Track-Cards or Chew Cards (CTCs) are a multiple species detection device specifically designed to cheaply map the distribution of low density small mammalian pests, principally possums but also rats mice and other pest species. It is an interference device, left in the field for about a week, which identifies animals present by tooth impressions made as they eat the bait material (possum dough) applied to the cards. The cards are a 9 x 18 cm rectangles, made of 550 g/m2 white plastic coreflute. Attractant Possum Dough lure is applied to the internal channels at either end of the card.
Contain highly palatable and long-lasting possum dough developed by Mike Holden.
Will last at least 6 months under normal storage.
