This is so helpful! DIY Wasp Catcher 1) Cut the neck off a plastic pop bottle. 2) Remove the bottle cap and flip the neck upside down and place it in the bottle opening that you just cut. 3) Tape together using packing tape or duct tape. 4) Bait the trap. The easiest is sugar and water, but I've also read that meat works well in the spring and early summer because wasps are attracted to protein, or other options are sugar and water, water and vinegar, beer, soda, even laundry detergent.
This is a carpenter bee catcher they will go in the holes (on all sides) and go toward the light and go in the bottle and can't get out, and die. I glued the bottle cap in a hole in the bottom. So when the ARE DEAD, you can unscrew it and dump them in the garbage. Or unscrew it put another cap on it and freeze or through away. This is a standard bird house, no doors or windows. I drilled 5/8 in holes on all sides. It works!!!
