It is the heat that causes the bugs to explode.
In addition to the harmful particles, Broce said the zappers only kill a small percentage of insects that are annoying or damaging to human health.
They also indiscriminately kills “beneficial” insects that help control other bugs.
Can a bug zapper catch fire?
This degree of voltage literally explodes the bugs, preventing an accumulation of dead bug carcasses at the bottom of the zapper (which can become a fire hazard), but it’s not enough to set fire to other flammable items usually found outdoors. There is concern, however, that bug zappers may be counter productive.
Are indoor bug zappers safe?
Bug zappers can certainly be used indoors – in fact, that’s one of their main uses. However, bug zappers that attract insects with ultraviolet light draw little electricity, are fairly inconspicuous (aside from the electric crackle when a bug is zapped), and can be used indoors or outdoors.
What bugs do bug zappers kill?
A study by the University of Delaware showed that over a period of 15 summer nights, 13,789 insects were killed among six devices. Of those insects killed, only 31 were biting insects. Mosquitoes are attracted to carbon dioxide and water vapor in the breath of mammals, not ultraviolet light.
Do bug zappers use a lot of electricity?
A large electric bug zapper uses as much as 100 watts of electricity. If you switch on two units and leave them on all night (it’s easy to forget to switch them off), they use 20 cents worth of electricity per day. There are several new designs of electronic mosquito-specific bug killers that are effective.
