Prevention of wasps and yellow jackets. Slice a fresh cucumber into thin slices and arrange them in a single layer on an aluminum pie plate. The cucumber must be fresh – the pan must be aluminum. The cucumber reacts with the aluminum and gives off a chemical reaction/scent that is undetectable to humans but drives wasps and yellow-jackets away and makes them flee the area.
Homemade Non-Toxic Wasp Spray / Repellant : combine together in a squirt bottle 2 cups of water + 1 teaspoon of peppermint oil + 1 teaspoon of dish soap (optional); wait until early morning or late evening hours when it looks like they’re sleeping, then shake and spray! You might need to apply the solution twice, but they will fall to the ground and die within seconds. Talk about a natural remedy!
natural bug spray Brew a pot of coffee and let it cool. Pour into spray bottle and spray on plants. It freaks out the bugs and gives your plants (if they are the type that need it) a tiny shot of nitrogen.
