To begin, you will need to drill a hole in the center of your 4x4. We used a 15/16 inch drill bit, however, you can use one that is 1 inch or a little under. Drill your hole about 5 inches deep.
TIP: Wrap masking tape around your drill bit at the 5-inch mark. Then you know to stop drilling when the tape reaches the wood.
Mark up about 2 1/2 inches from the end that you just drilled the hole into. Then drill holes in the center of each side as shown below. Keep your drill at about a 45-degree angle. Drill until you reach the 5-inch deep hole that you put in the bottom. Here you will want to use about a 3/4 inch drill bit. Repeat this same procedure on all four sides.
Now, if you have not already, you can cut off your 4 x 4 at around 7 inches long using a saw. Then just add some type of hook to the top for hanging.
Add a larger hole to the center of your mason jar lid. You can use a large drill bit for this just be sure to clamp down the lid well. Then screw the lid onto the bottom of your trap. Be sure to align the hole in the lid with the hole in the bore bee trap.
Finally, you just want to screw the mason jar onto the bottom of the trap.
