Locate the Nest
The first step is to find the nest of the wasps. These are generally well-concealed, but if you see a congregation of wasps, you know that the nest is nearby. The nests look like they are made of paper, and you are likely to find them near thick hedges and trees, and also near garages and lofts.
Initially, make sure that there are no places where wasps can make their nests. Do not leave rotting food outside, cover holes in the building with an appropriate filler such as wood filler, expanding foam or caulk. Lawn holes should also be covered over. There should be no exposed holes in eaves and lofts.
However, if you have located a wasp nest in your area, then necessary steps should be taken to get rid of the nests as soon as possible. This should generally be done before sunrise or after sunset, since at these times the wasps are all in their nests and can be killed all together. Wear appropriate protective clothing, since the wasp can sting through cotton and synthetic clothing very easily.
Stings and Infections
Wasps carry a great deal of venom in their stings, and if you are stung by one, you are exposed to dangerous bacteria and a mighty dose of venom. Hence, it is of immense importance that these nests are destroyed as soon as they have been discovered.
A single wasp can be handled easily with the help of a spray, especially made for flying insects such as the Insecto Wasp Destroyer Aerosol Spray. Spray cans such as these are useful and are quite capable of killing wasps.
One of the most effective wasp killers are the new powders available in the market. These are placed near the entrance of the nests and as the wasps enter their nests, they carry these powders in their feet and gradually kill off the residents of the nest. These powders do not have to be placed inside the nest, they can put around the holes and gaps where the wasps are seen exiting and entering. As with any chemicals anywhere, all instructions must be read and followed carefully, for an effective solution.
Where the nests can be seen easily, spray foams can be used effectively by spraying them directly into the nests. The sprays will soak the nests, killing all the wasps within it.
Nests in Outbuildings and Lofts
In these hard to reach nests, a fumer can be used. The fumer should be placed near the nest and the area should be vacated for at least three hours by all the family members. The smoke permeates all the holes in the buildings and is a very thorough cleanser of nests and wasps. Once again, it is imperative that all precautions are taken and that no one remains near the fumes until the requisite time duration for evacuation gets expired.
Avoid treating the nests if you have any allergy problems. Wasp stings can be fatal for people with allergies. In a situation like this, it makes sense to call the professional wasp killers and stay away from the areas. Wasps should be removed as early as possible, as they are a danger to the family. Any delays will only lead to larger nests and a greater congregation of the wasps.
