Bug Zapper Light Bulb has no toxic chemicals and is safe to use around children and pets. The Bug Bulb also has a powerful battery that can last a long time, but it can be recharged quickly using a USB cord. When I tried to move the bulb to a different location for testing, I found a bug on the metal element of the zapp. This ensures its performance and long-term durability in even the most challenging environments. It's possible that changing out your light bulbs will lead to fewer flying bugs, but you must also manage your expectation." Bug bulb light zappers work by attracting bugs using ultraviolet (UV). Also, the light serves as an attraction to pest so as to draw them closer for zapping. The Bug Bulb comes with a handy hook, making it easy to hang almost anywhere. It would seem that a more compact grid of smaller diameters wires would be more effective but wouldn't look nearly as nice on a shelf, or during an infomercial broadcast late at night. The LOHAS A1507 Bulb emits a warm amber glow that is sufficient to enjoy an evening outdoors without inviting the flying insects to join you. A free pair of replacement bulbs is included with the product to ensure it lasts as long as possible.
