Understanding What a Black Flag Bug Zapper Bulb Is
The Black Flag Bug Zapper Bulb is designed to attract and eliminate flying insects like mosquitoes and flies using ultraviolet light. It’s a simple yet powerful way to keep my outdoor and indoor spaces bug-free without harsh chemicals.
Choosing the Right Wattage for Your Needs
I noticed these bulbs come in different wattages, typically ranging from 15 to 40 watts. For smaller patios or indoor areas, a lower wattage bulb works well and saves energy. But for larger outdoor spaces, I preferred a higher wattage for broader coverage.

I wanted a bulb that wouldn’t spike my electricity bill, so energy efficiency was key. Many Black Flag Bug Zapper Bulbs are designed to be energy-efficient while offering a lifespan of several thousand hours, which means fewer replacements and more savings over time.
