How to Make a Bee Trap

Using a 2-liter Soda Bottle

Cut away the top third of a clean 2-liter soda bottle. Remove the cap. Use a utility knife to cut off the top of the bottle slightly below where the neck straightens. To cut an even line, wrap a piece of masking tape around the bottle to mark where you'll cut.

Invert the bottle top to nest it in the bottle bottom. Hold the bottle top so the capless end is facing downward. Insert this into the bottle bottom. Hold the bottle top in place at the top of the bottle bottom with your fingers. Staple the top to the bottom on four opposing sides. If you don't have a stapler, tape the seam between the inverted bottle top and the bottle bottom instead. If you want to reuse your traps, fasten the bottle top and bottom with clothespins. You only need to unfasten the clothespins to clean, empty, and refill your 2-liter bottle trap.

Drill holes and add cord to make a hanging trap. Drill two holes an inch (2.5 cm) below the top of the trap, with each hole on opposite sides of the bottle. Use a drill bit large enough to allow your cord to pass through. Feed one end apiece of a length of cord into the two holes holes. Knot the ends of the cord and it's ready to hang.

Use honey or sugar water as bait. Pour honey or sugar water directly into the bottom of the trap. You don't need much; a thin layer will be enough to attract bees. Bees will be attracted to the sweetness and won't be able to escape, eventually dying in the trap. Save the lives of bees by only using honey or sugar water. When you see a bee trapped inside, take it away from your home and carefully release it.

Poison bees with laundry soap. To ensure bees that enter your trap don't make it out alive, add a tablespoon (15 ml) of liquid laundry soap to your bait. Distribute the soap throughout the bait by stirring it with a utensil. The soap will poison and kill all bees that ingest it.

Position your traps near bee access points. Placing your traps too close to bee access points may actually draw more indoors. Prioritize locations in the sun. Sunlight will make the bait more effective and also cause bees to die in the trap faster. Hanging traps tend to attract bees better than ground traps. Ground traps, however, can be effective guarding window access points.

Check traps every two weeks. If you've fastened your bottle top and bottom with staples, you'll either need to remove the staples to clean and refill the trap or make a new one. Otherwise, remove the tape or clothespins, dump the contents of the trap, rinse it, and refill it with honey or sugar water. These traps will attract many kinds of insects, including ants. Use natural methods to prevent and remove ants.

Building a Mason Jar Carpenter Bee Trap

Mark a 45° angle on the 4x4 post. Lay your post flat on its long side. Use your square to draw a 45° angle from one corner of the post until the line ends at the opposite side edge. The angle, when cut, will form two edges about 7 in (17.8 cm) long and two that are about 4 in (10.2 cm) long.

Cut the post along the marked angle. Position your post somewhere it will be safe to cut with a saw. For example, you might clamp the unmarked edge to a workbench or scrap wood so you can cut the marked edge more easily. Cut the post along the marked angle with your circular saw. Use caution when operating a saw. Improper usage can result in serious injury. Always wear safety glasses and a face mask. Substitute a hand saw for a circular saw. However, cutting with a hand saw will take longer and require more effort.

Cut the opposite side of the post to finish incomplete cuts, if necessary. The blade of some saws might not extend all the way through the post. In this situation, turn the post over and mark the same angle on the opposite side. Cut the angle on the opposite side to finish the incomplete cut.

Drill a hole in the flat bottom of the post. Orient the flat bottom of your post, which is opposite the angled top, upwards. Use a tape measure and a pencil to mark the center of the flat bottom of the post. Use a 7/8-inch bit to drill a 4-inch (10.2 cm) deep hole at this center mark. Drill the hole on a straight up and down angle with respect to the flat bottom of the carpenter bee trap. If you're a poor estimator of distance, measure the length of your drill bit and note the point it is about 4 in (10.2 cm) long. Drill to this point.

Mark entry holes on the four sides of the post. Each of the four sides will need a hole to make your trap most efficient. Use a tape measure and pencil to mark one hole on each side. Each hole should be 2 in (5 cm) from the bottom edge and ¾ in (1.9 cm) from side edges.

Drill side entry holes upward on a 45° angle. Hold your square beside the hole to help you judge the angle. 45° is halfway between horizontal (flat) and vertical (up and down). Position your drill parallel to this angle and drill upward until the hole connects with the hole drilled in the bottom. Drill holes in this fashion at each of the marked points on the four sides of your post. All holes should connect with the straight hole drilled in the center of the post's flat bottom. The angle for your side entry holes doesn't have to be perfect. For quick, easy, and accurate angled holes, use a pocket jig as a guide. Pocket jigs can be bought at hardware stores.

Attaching the Mason Jar Base

Mark the lid of your mason jar with a permanent marker. Remove the flat part of the mason jar from the circular threaded part that fastens it. Measure and mark the center point of the lid. Divide the distance between the middle point and the outer edge in half on both sides. Mark these two points as well. The resulting three marks should form a straight line. The first mark will be the center of the lid, and the other two will be halfway between the center mark and the lid's outer edge.

Punch holes into your lid. Position your punch on top of one of the marks. Swing a hammer with firm, moderate force and hit the end of the punch to drive its tip through the metal at your mark. Repeat this for the two remaining marks. Place the lid on a piece of scrap wood or heavy metal to prevent the punch from damaging your work surface.

Drill a hole in the center of the mason jar lid. Turn the lid over so the punched side is facing downwards. Drill a hole at the center punch with a ½-in metal drill bit. This will create metal shavings, which can be sharp. Dispose metal shavings in the garbage. Drilling your center hole may have created metal burrs. Prevent cuts from these by removing them with a file.

Attach the assembled jar lid onto the bottom of the post. Fit the lid into its circular, threaded part. Align the hole in the center of the lid with the hole in the flat bottom of the post. Attach the lid by fastening it to the post with a screw in each of the two remaining punched lid holes.

Add an eye screw on top and hang your trap. Measure and mark the center point of the angled top of your carpenter bee trap. Drill a screw hole here for your eye hook. Insert the eye hook, screw the glass jar into the attached lid mount, and hang it to trap and kill carpenter bees.

Hang traps close to active bee holes. Carpenter bees will be attracted to the holes in your trap and crawl inside it to lay eggs. However, the 45° angle of the entry tunnels will confuse the bees, drawing them into the glass jar where they can't escape. Close up carpenter bee holes while they're away with caulk, wooden dowels, or specialized carpenter bee killing foam. Closed nesting holes will force carpenter bees to look for the most convenient new home, like your carpenter bee trap.
