How to make a wasp, hornet or yellow jacket trap from a 2 liter bottle. To keep the bees from getting in here (and keep them doing their good job!) just add apple cider vinegar. Bees don't like the sour, but wasps do.
To keep wasps from setting up a home near your front door or around your home - mix 2-3 tablespoons of Dawn dishsoap and about 2-3 cups of water. Put into a spray bottle, shake and that's it. Spray where they keep coming back to, to make a new nest. This will also kill them and drop them like a hat.
Who knew.... Wasp Trap and Killer - Fill the bottom of the bottle with one fourth of a cup of water, one teaspoon of dish soap, one teaspoon of sugar, and a teaspoon of alcohol. The soap and alcohol will kill wasps, and the sugar will attract wasps to your trap.
