You may not be aware of they fact that over 2,000 different species of wasps exist in the world. Each species is genetically unique, and all are beneficial, playing a significant role in our eco system.

But, the ones you’ll have to look out for are wasps that appear in late spring, or early summer. They include the Red Mason, the Bald-faced Hornet and the Yellow Jacket.

Fortunately, the majority of these wasp species are not out to attack humans, their main targets are other insects and arachnids, spiders and caterpillars. However, in some cases, wasps can be a nuisance to humans, especially when they nest near human dwellings or at entry points like doors and windows or as mail carriers.

The best Wasp sprays to consider buying are flying insecticides (aerosol sprays or pump sprays) you can pick up at your local hardware shop, to get rid of wasps and other flying insects.

However, when it comes to wasps, spraying your nest with a wasp nest spray is nothing short of a dangerous task. Although it’s easy to do, and it’s effective, it’s also a hazardous activity to perform.

Frequently Asked Questions (FAQ)

What is the most effective wasp spray?

The most effective wasp spray is the one that best suits your needs.

Ideally, you would like to know that the spray you are about to use to get rid of wasps and hornets will actually work on the particular type of buzzy creature you are dealing with.

Different types of wasps have different behaviors. Some will approach. Others will back away. Species of wasps also have different meanings behind their stinging attacks.

A wasp that bares its fangs at you is definitely being aggressive. If it simply flies towards you and inspects your activities, then it probably isn't feeling very hostile.

If it is backing away, consider the possibility that it is simply reading you. Wasps are actually very intelligent and exploratory. If you move towards it, it might consider you threatening.

Is wasp spray safe?

Proper precautions must be taken to use wasp spray safely. The biggest safety measures involve avoiding inhaling the spray and contacting your eyes. Contacting the eyes with wasp spray can result in more than just a stinging sensation. It may cause significant pain, scratching of the eyeball, and potential damage.

It is recommended that you wear safety glasses or goggles to keep the spray out of your eyes and mouth. If you are using the spray indoors, you may want to turn on a fan to help disperse the spray. Be aware that the spray may not rid your home of every wasp.

If the wasps have molted and you can see their exoskeleton shells, do not attempt to spray them. Wasp sprays do little to help rid you of the live wasps.

What kills Hornets instantly?

If you follow the directions on most wasp sprays, a single spray to a few wasps will kill them. The problem, is finding enough wasps nearby that will stay in the area while the spray sets in.

I found the most effective wasp spray to be a product labeled as a microbial insecticide. Unlike most sprays, which are designed to irritate the wasps to kill them, these microbial sprays contain a cocktail of microbes and diseases that infect the wasp and, in a couple of days, kill them.

I found that these microbial sprays are also effective on fleas, ticks, spiders, flies, mosquitoes, and gnats. Best of all, if you get sprayed by wasps, the microbe does not affect you. In fact, in one episode, the microbiologist who developed the product splashed the mixture on his own skin and held up a vial for the camera to see.
