1
Bury a plastic pot (such as a yoghurt pot) into the ground, so the rim is at ground level.

2
Include a few leaves as hiding places, but low down so beetles can’t climb out.

3
Position some stones around the rim, and a piece of wood on top to keep the rain out.

4
Check the trap the next day and note what you see. Release the insects afterwards.
