The Beetle Jail recipe is not exact, about 2 desert spoons of pollen, 1 desert spoon honey and about 1/2 teaspoon vegemite (yeast extract).
Add water to make into a paste. The lure is then used in the Beetle jail in the hive. We only run the Beetle jails in hives that have a lot of beetles, if you see 5-6 when you lift the lid then the hive will get a Beetle jail.
I don't know if it would lure free flying beetles to somewhere else other than a hive?
