UV Fly Killers for Kitchens and Cafés: How to Choose

UV fly killers are common in food businesses, but placement and maintenance decide whether they work.

The short answer

UV fly killers use ultraviolet light to attract flying insects to a glue board or grid. Choose a unit sized to the area, preferably glue-board types in food areas to avoid scattering insect fragments, and place them away from food prep and competing light, near entrances but not directly in view from outside. Change lamps and boards on schedule and log service for audits.

How to choose

1. Match unit size to the room.
2. Prefer glue-board types in food areas.
3. Look for easy maintenance.
4. Check safety and approvals.

Placement

• Away from food preparation and open food.

When to call a professional
