Any ideas why bees sometimes trash sealed brood when the colony is treated with Apiguard. I have noticed this in previous years as well, with large quantities of pupal limbs on the Varroa board.
Fortunately it is associated with effective Apiguard treatment and such colonies recover well and subsequently drop few Varroa with the Christmas oxalic acid treatment.
