Welcome on our web site OHARKOVI.COM

We are the first manufacturer of evaporators oxalic acid suppression varroa destructor in the Czech Republic. Oxalic acid is not yet approved in the Czech Republic but is much used. We strive for approval and registration of oxalic acid (OA) as a registered treatment for bees in the country.

Treatment with oxalic acid (oxalic acid) is used a lot in Italy, Poland, Austria, and also in many other neighboring countries. Most are exported to the USA. The effectiveness in terms of foreign study indicates approximately 95% and produces no resistance. Mites die even three weeks after application, even though the substance does not get under closed cells due to the fact that the mites cause burns to the intake tract and therefore are not able to suck the hemolymph of bees and die hunger. 1 g of acid is used for one boxes with frame size 39x24 cm.

Furthermore, we are developing to production Trunk bees solar recharger, automatic operation control for honey-extractor and Typhoon oxalic acid vaporizer for commercial beekeepers. - In production May 2016

Our main goal is a satisfied customer and a quality product with a long life.
