So, you've tried those wasp traps from the local stores and might have even tried traps with raw meat, but those pesky wasps are not interested in your traps? You just might be hanging up the wrong trap. Lager Sagers, one of the hosts of the KSL Greenhouse show, says that the wasps you see in swarms around your yard and attacking your ripe fruit are probably not the same kind of wasps we had ten years ago. They might be the European Paper Wasp, a species not native to the U.S. In the best tradition of self-reliance, the trap you need might be one of your own making. No fancy pheromes --- just an old plastic soda bottle, fruit juice, soap and water.
Lager Sagers explains about this wasp and the trap in the following article on KSL: The Right Trap for the Right Wasp
If you, like me, need a visual illustration, I found the trap Mr. Sagers describes on a different website: Do It Yourself Wasp Control
If you plan to make one of these traps, it is important to use the correct proportions: 1 part fruit juice to 10 parts water + 1 tsp. liquid detergent. These proportions encourage fermentation of the mixture, which draws the wasps.
Wouldn't this make a great project for a youth group?
