Chew cards are 2-3mm thick plastic panels with a tasty - to predators - 'lure' pushed into channels inside them. Predators chew the card to get to the lure, and by looking at the teeth marks it's surprisingly easy to determine what animal has done the chewing. The images below will help you identify your pest.
Here's the summary
- Nibbles on one side only = mice
- Bites through both sides = rats
- Punctures = cats, stoats, ferrets or weasels
- Crushed / seagull-shaped dents = possums
Read on for photos and notes.
Here's how you can tell what animal made different chew marks. Click on the photos for a closer look.
If only one side is chewed away, you've got a mouse, or probably a whole family of them.
Rats will chew right through a card and don't leave dents or punctures like possums or cats.
If you've got small round puncture marks, they're made by a cat, stoat, weasel or ferret.
Cat or mustelid
