Bite me ... the chew card test
31 May 2018

Do you want to know what's been eating your fruit or helping itself to the chook's food?  We've got just the tool for you!

Time efficient, accurate and cost effective, chew-track card technology (“CTC”) enables users to identify which pests are present in a particular area.

These cards are used to record the teeth marks and biting habits of small mammalian predators such as

  • Possums
  • Stoats
  • Weasels
  • Hedgehogs
  • Rabbits
  • Rats
  • Mice
  • Feral cats

Chew-track card technology is best suited to sites with relatively low density pest populations, as excessive biting will destroy individual bite marks and compromise the accuracy of the test. Chew-track cards can also be used for ongoing monitoring of affected sites.

Chew-track cards (9 x 18 cm) are made from corflute – the same material as your average real estate sign. What makes this material so suitable for CTC purposes is the hollow fluting inside the card. Once attractant bait has been pressed into these cavities (to a depth of around 2 cm) the card is simply folded and nailed to a vertical structure such as a post or tree where it remains for approximately one week (Recommended CTC placement height is 30cm from ground. Lower for smaller predators such as hedgehogs)

Below are samples of typical teeth and bite marks. While most predators gnaw or bite the cards, possums use their teeth to scrape from the centre of the card towards the edge - the pressure pushing the bait out of the card cavity.
