How Does a Solar Bug Zapper Work at Night?

Nothing beats sitting on your back porch on a warm summer evening - until the insects start swarming. Bug zappers help keep insects at bay and away from you by using electricity. Solar-powered bug zappers work the same as traditional bug zappers, even at night, but these devices harvest solar power and don't rely on electricity.
Power Consumption
Solar bug zappers have a built-in solar panel,typically placed on the top of the device to maximize sun exposure. By placing the bug zapper in an area with moderate to direct sunlight, the solar panel can harvest energy from the sun, which is used to charge a battery.On average,a sunny day can provide eight to 12 hours of power, according to the Louisiana Department of Environmental Quality.(See Reference 1)However, solar bug zappers can work overnight after a day of only moderate sun exposure.
Nighttime Operation
The bug zapper contains one or more ultraviolet light bulbs attached to the battery. As the battery receives a full charge during the day from the energy harvested by the solar panels, it can provide a power source to the UV light bulb at night. Most solar bug zappers harvest enough energy to power the UV light bulb through the majority of the night.
Some solar bug zappers also have a feature that turns on the UV light bulb automatically at dusk, providing immediate relief from night-roaming pests.
Pest Control
Flying insects are naturally drawn to light sources, such as ultraviolet light. At night, the light emitting from the UV light bulb inside the solar bug zapper draws in insects. Once the insects come in contact with the bug zapper, the light bulb emits an electrical charge that eliminates the insect on contact. Generally, solar bug zappers are placed above the ground and only intended to handle flying pests such as mosquitoes and gnats.
Other Considerations
Solar bug zappers are an effective way to get rid of outdoor flying insects without the use of harsh chemicals. However, bug zappers will eliminate any kind of flying pest that comes into contact with the device, including insects that are beneficial to the environment. Dr.
Doug Tallamy, a University of Delaware professor, collected bug samples from six different bug zappers. Of the nearly 14,000 insects collect, only 31 were biting insects. The rest were harmless pests or insects that benefited the environment, according to the study. (See Reference 2)
