The main objective is to avoid a critical level of varroa mite infestation that could lead to colony losses. Varroa monitoring is used to estimate the degree of varroa infestation, optimize the time of treatment, and confirm that treatment was successful.
Monitoring also makes it possible to choose the most efficient control product, determine if treatment is needed soon, or if you can wait until later in the year. Knowing your hives’ varroa levels in the late summer and fall will aid in making treatment decisions at that time, and help ensure that your colonies do not enter the winter with high mite loads. This will help reduce winter colony losses and give you stronger spring colonies. The cost of replacing a colony of honey bees, feeding the new hive, and lost honey production is a good argument in favor of regular monitoring.
