Honey bee colony treated in spring (after the first inspection of bee families) in the summer-autumn period (after pumping of honey) by placing preparation strips in beehives 2 strips on 10 – 12 nesting frames. For small bee colony (up to 6 frames) and nucleus boxes enough 1 strips that are placed in the center of the nest. Before using the need to do a hole at one end of the strip, stretch through it and lock pin stripes vertically exactly in the center beehive (in the middle part of it) between two frames of bee nests. In a weak honeybee colony hung one strip between 3 and 4 honeycombs, in strong – one strip between 3 and 4, and the second strip between 7 and 8 honeycombs. Strips leave in a honey-bee colony for a period of 3 to 30 days depending on the number of the brood.
