Bug zapper traps may be installed indoors, or outdoors if they are constructed to withstand the effects of weather. However, they are not effective at killing biting insects (female mosquitoes and other insects) outdoors, [4] [5] being much more effective at attracting and killing other harmless and beneficial insects.
The handle contains a battery-powered high-voltage generator. The circuit is a minimalist self-oscillating voltage booster, that is small, low-cost, composed of very few components, and continuing to operate when the battery is depleted to a fraction of its original voltage, a so-called Joule thief circuit.

Electronic pest control is the name given to any of several types of electrically powered devices designed to repel or eliminate pests, usually rodents or insects. Since these devices are not regulated under the Federal Insecticide, Fungicide, and Rodenticide Act in the United States, the EPA does not require the same kind of efficacy testing that it does for chemical pesticides.
A sprinkler system timer is an electrical device that is used to set an irrigation sprinkler system to come on automatically at a certain time. Irrigation timers first appeared in the early 1960s to control large-radius lawn sprinklers, which at the time usually contained their own electrically operated valve (most golf-course sprinklers still use this type of actuation).
A fogging car used against the Aedes aegypti mosquito during a dengue fever outbreak in Coronel Fabriciano, Brazil, 2016. Fogging is a technique used for killing insects that involves using a fine pesticide spray which is directed by a blower. In some cases, a hot vapour may be used to carry the spray and keep it airborne for longer.
For example, larvicides can be used in mosquito breeding zones; insecticides can be applied to house walls or bed nets, and use of personal repellents can reduce incidence of insect bites and thus infection. The use of pesticides for vector control is promoted by the World Health Organization (WHO) and has proven to be highly effective. [7]
A mosquito laser is a proposed device that would use lasers to kill mosquitoes. The primary goal would be to reduce malaria infection rates. In 2007, the Bill & Melinda Gates Foundation asked Intellectual Ventures to find a way to fight and eventually end malaria. [ 1 ]
A major application of current loops is the industry de facto standard 4–20 mA current loop for process control applications, where they are extensively used to carry signals from process instrumentation to proportional–integral–derivative (PID) controllers, supervisory control and data acquisition (SCADA) systems, and programmable logic ...
