Sitting outside when the weather is warm is one of the most enjoyable things about the spring and summer seasons. Unfortunately, there are a variety of pests that can be very determined to spoil your time outdoors. Wasps are territorial, and will sting anyone they consider to be invading "their" space. Wasp stings can be quite painful and extremely dangerous, and you should avoid these insects completely if you are allergic, or think you may react violently. Fortunately, you can easily rid your yard of wasps and their nests using common household products.
Mix 1 part bleach and 2 parts clean water in a lawn sprayer with a wand or a spray bottle that is strong enough to spray a distance of at least 2 feet.
Dress in a long-sleeved top, pants and shoes that cover your feet completely, and protective gloves. You may also wish to cover your face with a stocking cap. Leave as little skin as possible exposed to prevent being stung.
Stand at least 2 feet away from the wasp nest, or where they are swarming. Move farther away, if you have a far-reaching lawn sprayer.
Soak the wasps and their nest with the bleach water. Realize that the wasps will not drop immediately, so be ready to move quickly. However, after a few minutes, the wasps will begin to die and fall to the ground.
Strike the nest and knock it from wherever it is hanging when you see that the vast majority, if not all, of the wasps are dead.
Drop bricks or large rocks onto the nest to kill any young wasps or pregnant females that may be hidden inside. This will also prevent other wasps from moving into a whole nest left on the ground.
