MG,
First be sure your hive is level. Put a half inch to 1 inch of veg. oil in the tray of the West trap. The 3 wooden strips should be nailed together and the beetle trap sits inside this and rests on the bottom board between it and the 1st super. It works well if used correctly. Post again if you need more details as a lot of us in the South are using it with success. Good luck.
