Most times of the year, it’s exciting to see colonies with frames of brood, but at this time of the year in Pennsylvania, it’s the opposite of what you want. This time of year— from now until the days start getting longer (winter solstice)—is a perfect time to do an organic treatment for varroa mites, because in PA it is typically a window of time where there is little to no brood present (where the mites tend to hide and reproduce). The time window may vary based on the location and your genetics (Italian leaning genetics tend to keep brood in the nest longer). Treatment using an Oxalic acid dribble is one approach, and we have syringes and Oxalic acid in stock at the farm shop, if you’re going to take that approach. We also have Oxalic acid vaporizers available for rent (either corded and battery powered, to fit your situation). This late fall/winter treatment is a good way to ensure your bees are clean going into spring. In our operation, we’ve found that a November/December Oxalic acid treatment means that we don’t see mite levels increasing until mid summer. We’re open on Friday from 9am to 8pm and other days by appointment, and call or message ahead if you’re planning on a rental so we can verify availability. We will not be open next Friday (November 24).
