The purpose of After the winter to spring inspection is to quickly determine if all is well. The hives [[cleansing flight]] it should not be opened evaluated if the colony needs to be treated for longVarroa. To find out if the colony needs to be treated, since count the cooling down number of brood can lead dead mites on the bottom board over 7 to stress and subsequently to disease10 days. Also there If you find more than an average of 1 mite per day you should consider treating the colony.Treatment options:* [[Oxalic acid treatment|Oxalic acid]]. Trickling of 4ml 3.2% per fully occupied beeway{{#info: A beeway is the space between the combs in a risk hive. | <icon> }} on adult bees.* Formic acid treatment. Recommended every 3 years to also treat for tracheal mite. Please note that formic acid can kill brood or even adult bees at higher temperatures.* [[Drone brood removal]] in late spring and the queen may be balled beginning of the summer season. Nordic brown bees usually produce fewer drones compared to other bees and die (''Link needed for balling queen'')drone removal is usually not done in breeding colonies. Drone brood removal is effective in removing reproducing mites, which also helps controlling the number of mites later in the season.
Hence the main two signs to note are[[Category:Varroa]] #Is there enough food in the colony to survive the coming weeks?<br />If not, provide food in form of a small portion of warm sugar candy placed over the bees to conserve their heat.#Is there worker brood in the center of the frames? <br />If there is, the queen is present and the colony will develop well. If not, then the colony is in trouble and it is best find to another colony to combine it with; preferably a weak colony.[[Category:Spring]]
