The varroa population is growing at an exponential rate.
Every month it doubles.1 Therefore it is important not to rely solely on a late-season treatment.
After 25 years of use in beekeeping, Apivar still showed the best efficacy among varroa mite treatments tested in France in 2021.
Varroa management has become a necessary and routine task for beekeepers globally over the last decades. Without strategic varroa management, beekeepers risk the health and survival of their colonies.
Finding the best treatment for varroa mites can be quite challenging for beekeepers. Here are 3 products to help you contain the mite infestation and make your bees happy (+ Bonus at the end!).
A research group from the University of Guelph (Ontario, Canada) has now taken a closer look at varroa mite sensitivity towards different miticides in the province (amitraz, flumethrin, tau-fluvalinate).
As the days are getting longer, and we are all looking forward to those extra rays of sunshine, you are not alone in the desire to stretch your legs and get fit for the warm season. Your bees are “stretching their antennae” too – so to speak – to prepare for a new colony buildup.

According to a survey conducted each year in Eastern France, the later the treatment is applied, the higher the winter losses. Study conducted in 2020 on more than 29,000 hives.

The varroa population was significantly positively correlated with maximum (r = 0.659) and minimum (r = 0.648) temperature.
