Curtis Rand, our Forester reports: “The recent late cold snap – it happened 2 years ago and killed almost all of the hemlock woolly adelgid because it hits them late in winter when the larvae are starting to move around and they are vulnerable to freezing.” The woolly adelgid is a destructive pest that affects our beautiful and historic eastern Hemlocks.
This is the whole post. Curtis says we should be celebrating. We had a cold snap in late January early-mid February this year. The cold snap 2 years ago killed almost all the hemlock woolly adelgid larvae. Curtis concludes that the cold snap this winter is likely to cause similar high mortality to the larvae as the cold snap 2 years ago. That is good news.
