The attraction of mosquitoes and flies to UV LED light is mainly related to the phototaxis of these insects. Most flying insects, including mosquitoes and flies, have compound eyes that are highly sensitive to ultraviolet (UV) wavelengths (typically ranging from 300–400 nm). In nature, UV light is a key component of sunlight, which insects rely on to navigate,UV LED lights emit wavelengths that mimic natural UV radiation, thus luring these insects toward the light source.

  Stable Wavelength Output

Glue board

Traps insects securely upon contact Prevents trapped pests from escaping Captures flies, mosquitoes and other flying insects effectively
The adhesive board (or sticky board) inside the fly trap serves as a non-toxic capture medium. Once flying insects are lured by the 365 nm UV LED light and land on the board, they will be instantly stuck to the high-tack adhesive surface, ensuring they cannot escape and are eliminated without chemical residues.
Designed for easy replacement, the sticky board provides a hygienic, hassle-free solution for pest disposal. It effectively collects and contains trapped insects, keeping the surrounding environment clean and reducing the spread of bacteria carried by flies.

Creates a downward airflow to suck in flying insects Enhances capture efficiency by preventing insect escape Works with UV LED to draw pests into the capture zone The built-in fan of the fly trap generates a steady, targeted airflow once activated. When flying insects are lured by the 365 nm UV LED light and approach the device, the airflow instantly sucks them into the internal capture drawer.
Unlike passive sticky traps, the fan-powered design eliminates the need for insects to land on the adhesive surface actively. The continuous airflow pulls pests into the trap quickly, making the device more efficient for high-density fly infestations in commercial spaces (e.g., restaurants, farms) and residential areas.
