Your bees - stronger

Strengthen colony-level defense against mites and disease by breeding with UBeeO™

Apply UBeeO™

Spray the UBeeO™ mix onto a small test area of capped brood and return the frame to the colony

Let the bees work

Hygienic worker bees will respond to UBeeO™ by uncapping brood cells in the test area 

Calculate UBeeO™ Score

After just two hours, the colony’s UBeeO™ response is ready to be graded

The UBeeO™ Score is the percentage of cells uncapped by the end of the testing period – the more cells uncapped, the higher the score 

UBeeO™ Scores can fall into three categories:

Low UBeeO™ Scores

Medium UBeeO™ Scores

High UBeeO™ Scores

0-39%
40-59%
60-100%

Peer-reviewed data show that untreated High UBeeO™ colonies are able to maintain mite loads below treatment thresholds and are more likely to survive winter.

Low UBeeO™ colonies may require additional mite monitoring and treatment to improve survival chances.
