Dermvia uses a built-in UV light to attract mosquitoes, flies, gnats, and other flying insects. When they approach, a high-voltage grid safely eliminates them on contact. During the day, the solar panel charges the internal battery. When darkness falls, the light sensor automatically activates the unit — no manual input needed.

Yes. Dermvia carries an IP65 waterproof rating, which means it's fully protected against rain, garden sprinklers, and high-pressure water jets. The internal components and solar panel are sealed and tested for year-round outdoor use in all climates.

A fully charged battery provides 8–12 hours of continuous operation — more than enough for an entire night. On a typical sunny day, the solar panel reaches full charge in 6–8 hours. Even on partial sun days, Dermvia stores enough energy to operate through the evening.

Absolutely. Dermvia uses a high-efficiency monocrystalline solar panel that continues charging even in low-light, overcast conditions. While a full sun day provides the optimal charge, cloudy days still generate enough power to run the unit for several hours at night. For extended cloudy periods, the unit also supports USB charging as a backup.

Yes — completely. Dermvia contains zero pesticides, insecticides, or toxic chemicals of any kind. The electrified grid is fully enclosed within a protective outer cage, making accidental contact virtually impossible. It produces no harmful fumes, no smoke, and no smell. Thousands of families use Dermvia safely around young children, dogs, cats, and other pets every day.
