Simple Homemade Yellow Jacket Trap.
This method is NON-TOXIC and for the most part pet and wildlife friendly due to the harmless components that are used to build the "system." There are quite a few commercial products on the market to eliminate yellow jackets but this one doesn't cost anything and I can guarantee its an extremely effective way to rid your yard or campsite of the yellow hoards in just a day or two.
You will need the following components:
Make a tripod out of the sticks and tie wires as shown in the photo.
Bend the short piece of wire into a hook shape and attach the string.
Add about 1 or 2 inches of water to the dish pan and mix the liquid soap in the water. Stir SLOWLY - you DON'T want any soap bubbles floating on the water.
Insert the fish meat on the wire hook.
Tie the string to the top of the tripod so that the meat is hanging ONE HALF INCH above the water level in the pan.
Do Not get soapy water on any portion of the fish!
How It Works: The yellow jackets love fish and will begin to cut off small pieces to take back to the nest. In their "excitement" of buzzing around the bait a few will occasionally hit the water. The soap in the water breaks the surface tension of the waterproof coating on the yellow jacket and it instantly sinks in the water and drowns in a few seconds. Some yellow jackets will successfully haul a piece of meat back to the nest and tell all the other gatherers in the nest where this great food source is. Soon all the wasps from the nest will be working on this fish and over a period of time, all will eventually make mistakes and either fall off the fish and into the water or bump other wasps flying around and knock themselves in the drink, then its curtains for them too. It only takes a day or two to wipe out nearly every yellow jacket in your area.
Put the trap on a table or other high area outside so that kids and pets will not be able to get close to it. A piece of fish with vertical sides works best for having the insects fall off easier.
