Esschert Design Fly Deterrent Teardrop

The deterrent works through light refraction. When filled with water, the curved glass creates visual distortions that confuse and repel flies, encouraging them to avoid the immediate area without the use of chemicals.

Maintenance is minimal. Simply rinse the glass vessel occasionally to keep it clear of debris or algae buildup so the light can refract properly. You may also need to top off the water level if it evaporates during hot weather.

While it can be hung anywhere, it is most effective in areas with natural light. Direct sunlight enhances the refraction effect, making the visual deterrent more noticeable to pests.

Yes, the glass is designed for outdoor use. However, like any glass decor, it should be taken down during severe storms or high winds to prevent it from swinging and breaking against structures.

The coverage area depends on the size of your space. For a standard patio, one unit is a good starting point, but placing multiple units around the perimeter of your seating area will provide more comprehensive coverage.
