November 15, 2017: Winter moths, previously written up (Nov 2014 and May 2016) as an invasive species, will soon be starting to emerge from their pupal state, triggered by the first few frosts. If you start seeing large numbers of moths flying around in the evening, it’s time. And if you intend to protect your trees, act now. Garden supply stores, including Russell's Garden Center (Wayland), carry Tree Tanglefoot in 15-ounce containers. One container should be enough for a few trees. The product can also be ordered on line in that size or five-pound pails.
