How to Make Your Own Wasp Trap?

A simple wasp trap to make is a Water Trap. Use a razor knife to cut the top from a 2 liter plastic soda bottle. You cut just above the shoulder of the bottle. Go ahead and throw that lid into the recycling bin. Fill the bottle with water about halfway. Then you coat the neck with jelly or jam, invert it and set it back on the bottle. (upside down.) Then just use two small pieces of tape to hold it in place. Just a few drops of dish soap in the water will make it harder for the wasps to tread water and will cause them to die faster.
