After the cleansing flight it should be evaluated if the colony needs to be treated for Varroa. To find out if the colony needs to be treated, count the number of dead mites on the bottom board over 7 to 10 days. If you find more than an average of 1 mite per day you should consider treating the colony. Treatment options:
