What are gypsy moths?

Gypsy moths are an invasive and destructive pest that pose a risk to tree health by severely defoliating deciduous and coniferous trees. The larva hatch in April to June. The caterpillar stage is when gypsy moths are the most damaging to our tree populations as they eat the leaves. Large populations of gypsy moths have a larger impact on our environment and our forests. Continuous defoliation causes the tree to lose its strength and can eventually lead to the tree dying.
