Bug zappers to control insects: How effective are bug zappers at controlling insects?
Bug zappers work by emitting light to attract insects. Many people think they are highly effective because they make a noise signaling another insect has been killed. However, they are probably not destroying bugs in numbers great enough to make much difference. If you decide to use a bug zapper, locate the device away from the area to be protected. Because bugs will be attracted, do not place them near a patio or area that you want to be bug free. Remember that there are many beneficial bugs in the garden. Bug lights do not know the difference between a good bug and a bad bug. They all get zapped. People often ask about using citronella candles to control pests. It is true that they do work, but only in the five-foot area where the smoke is concentrated. Beyond that distance, the benefit is lost. To enjoy a pest-free patio, try this trick. Place several oscillating fans around the area to keep the pests at bay. Insects such as gnats and mosquitoes are worse on calm, still nights.
