Try marking the tree below your trap with a blaze. Make up a dry mix then spread the blaze on the tree under your trap and on the ground nearby. Here’s one tried and tested recipe from Cam Speedy of Wildlife Management Associates Ltd:
- 10 parts flour
- 1 part icing sugar
- 1 part milk powder (optional)
- a touch of peach essence (or use cinnamon powder).
Other aromas which have had some success include aniseed, curry and raspberry.
