Scalvini queen cage

The Scalvini cage is a recent development for keeping the queen during varroa treatment. The queen can be kept in here, she can lay eggs but these cells are not built out because there is too little space. No brood is added and after 21 days all brood has emerged, creating a broodless period. Because there is no more capped brood, this period is very suitable for treating bees against varroa with oxalic acid. Dripping, spraying or vaporizing.
