Although they are not hungry for leaves like they are in the larval stage (Winter Worm), it is wise to take notice of Winter Moth volume this time of year.
The little moths that congregate around our exterior lights are actually the pesky, foliage chewing winter worms that devastate our trees in the spring and early summer while in the larval stage. Even though the moths are not a danger to our trees at this point, it is good to keep an eye out for an abundance of moths. It is safe to assume that if moth volume is very high, you may experience excessive damage from the caterpillar-form of these pests come spring time.
Winter Moths have become a nuissance across the North Shore and Greater Boston Area, defoliating a tremendous amount of deciduous trees in our region. During the late fall and early winter, the male winter moths will emerge from their summer vacation spot (the ground) as moths and fly around as long as weather permits. The females, who have no wings, emerge from the ground at the same time and crawl up trees to lay their eggs. These are the eggs that will hatch next spring, producing an army of foliage eating winter worms.
With winter worm damage being so extensive in the past few years we encourage homeowners to sign up for Target Winter Moth Treatments. A target treatment done in the early spring will mitigate your winter moth risk, and is highly recommended if you've experienced damage in the past, or are seeing an abundance of moths flying around now.
If you're concerned about winter worm damage, please request a free consultation with one of our Certified Arborists. Signing up for a preventative pest management treatment or program this winter can also help you save money, as we provide a 10% discount for early signups.
Without preventative treatments, winter worm damage can be severe, effectively defoliating an entire tree or group of trees.
