Yes, the operation of the Varroa Stopper emitter is safe. The emitter frequency has been carefully selected and thoroughly tested. In our research, we took into account the effects of experimenting with the frequencies of sonic devices. Prof. Dr. Hab. Jerzy Wilde discusses the potential effects of improper frequency setting in his works, which confirms our approach to safety of use.

The ultrasonic shower is characterized by the presence of not only adult female Varroa, but also larval forms of the parasite, such as protonymphs and deutonymphs, as well as light brown young females and males Varroa. Unlike the "chemical" shower, which consists mainly of adult, brown female Varroa, the ultrasonic shower is more diverse and contains different developmental stages of the parasite.

The effects of the emitter can be observed within a few days of its activation. Beekeepers often notice the so-called "sonic fall" in the form of parasites that fall on the bottom of the hive. Particularly intensive fall can occur during the late summer reinvasion, which allows monitoring the effectiveness of the method. Regular checking of hygienic bottoms and observing bee activity will also help in assessing the effects of the device.

In the event of an emitter failure, we encourage you to contact our customer service department. Each device is covered by a two-year warranty, and the emitter's lifespan is several years. Our technicians will help diagnose the problem and, if necessary, propose repair or replacement of the device.

It is recommended to place the device under the bottom of the hive and cover it with foil, which will protect it from moisture.
