If you to stay in beekeeping for any length of time then, you will come across the most invasive pests of the honeybee colony- the dreaded Varroa destructor. This pesky insect is often the downfall of many hives, even when the beekeeper performs proper Integrated Pest Management (IPM), because there seems to be no cure for the Varroa as of yet.. During the past and critical first year of beekeeping, I had little trouble with these pests. However, 2018 is a different story because the hives are thriving and thousands of foragers are out and about every day the weather permits and they are here. Varroa mites can invade any hive and August is the time to check and start treating for these little red pests. They are more numerous than any “tick on a dog, but when the beekeeper has 50,000 and more honeybees in a single “double-deep” box hive it is understandable. The problem is they are akin to fleas, ticks, and mosquitos as they cannot be eliminated, just managed to the best of beekeeper’s ability and finances.
This hive is my proprietary Z-Top Hive design and has the capacity of holding thirty-one deep frames for brood or honey, one block frame- separate active frames form inactive frames, and one “bee escape” frame- used during the honey flows.
Do not be fooled by thinking that your honeybees are not going to get infested with the deadly parasite called the “Varroa Destructor.” Even beekeepers who monitor and treat for this unwanted pest have the unpleasant experience of finding “dead-outs” in the apiary. Two weeks after this Api-Var treatment was completed I had less than five mites showing up on the “sticky boards” of any hive. Unfortunately, the Varroa had already infected a majority of the bees in each hive and by January 2019 four of the five hives died. These Varroa depleted the body fats of the bees and they never fully recovered because, their immune system was compromised and these hives froze to death during December 18, 2018 and January 2, 2019.
I have learned this truth from my honeybees, “The stronger the queen is genetically, the better chances the hive will survive a cold harsh winter.” My research and documentation indicates that a genetically strong queen produces more bees who in turn produce more honey, and who are able to “resist,” not eliminate the Varroa destructor. The remaining hive has a 21-month old queen from 2017, who has out-performed all the other hives in bee numbers and honey production. Knowing this fact, I am not a beekeeper who “executes” the queen every year- as son beekeepers do-, and just to get a new queen.
As long as the queen is producing positive results in the areas of mite resistance, bee numbers, and honey production she stays in the hive. I believe that queens should be replaced only when: 1) she produces few bees, 2) she produces bees with a bad temperament, or 3) the bees she produces are unable to resist the Varroa destructor.
It is no secret to the beekeeper that regardless how hard you try to manage and protect your honeybees that are going to be “varroa mites” in the hive. Treating all the hives in early spring with oxalic acid and in the late summer with ApiVar helped, however it did not “cure” the problem. Personally, I expected to lose twenty to thirty percent of the apiary but, I never expected that all the hives would die in the same manner and over night. After checking my apiary inspection data in the HiveSmartHQ app, I discovered some interesting facts revealed over seventy-five inspections during the 2018 -19 season:
After the apiary died I sent two hive samples to the USDA Testing Facility in Beltsville, Maryland for a “free” analysis of any disease which may have contributed to Colony Collapse Disorder (CCD) and final dead-outs. The reports indicated no American or European foul-brood diseases and that the colonies died from affects of the varroa destructor.
