Airbourne insects are attracted to ultraviolet (UV) light. UV light placed
behind an electric grid can be used to attract and electrocute flying
insects. Such traps are usually a requirement in food preparation establishments
such as butchers, for hygiene. They are also found at holiday resorts
and commercial green houses to reduce pests. A domestic scale bug killer
is available for general use.
