Buying Guide
What should you consider when choosing a bug zapper that kills flies?
- Coverage area: Match the device to your space. Small patios benefit from compact zappers; larger yards may need models like Flowtron that cover expansive areas.
- Voltage and grid design: Higher voltage generally means faster kill, but ensure safe, protective grids to reduce accidental contact.
- Attraction method: UV light, dual-color LEDs, and octenol attractants are common. Dual wavelengths can improve lure in low-light conditions.
- Indoor vs outdoor use: Some models are designed for both, with weatherproof housings; others are better indoors for kitchens or offices.
- Power source and cord length: Consider plug-in options and cord length for flexible placement without extension cords.
- Safety features: Look for child/pet safety gaps and sturdy enclosures to avoid accidental shocks or injuries.
