While these bug zappers are very effective at killing insects, it’s the type of insects they kill that we should think about. For example, if the purpose is to get rid of biting insects like mosquitos, then bug zappers might not be as effective as you think. This is because a mosquito is attracted to humans and animals more than it is attracted to light, so you are still likely to be bitten by them even with a bug zapper.
We know many of us are afraid of all types of insects and would rather have them all be zapped than enter our homes, but this type of repellent also kills many insects that do not bite and that are badly needed for the proper functioning of the environment.
There is also a level of concern for human health with the use of bug zappers, this is because as a bug is zapped it is disintegrated and blown into the surrounding air. This can create all types of bacteria from the insect to become airborne up to a distance of 7 feet. This means that anyone breathing this in could possibly become contaminated with these bacteria, and its clear to see the potential hazard if it is positioned around food preparation.
As we can see, while it may seem that bug zappers are a fool proof way of controlling insects around your home, they may not be getting rid of the right kinds of insects.
