What to do if you find a gypsy moth?
Apply Bacillus thuringiensis, var. kurstaki or Monterey Garden Insect Spray (Spinosad) to the leaves of trees to kill gypsy moth caterpillars. For best results, sprays must be applied when caterpillars are young, less than one inch long. In instances where populations are high, two (or more!)
How do you stop a gypsy moth infestation?
Sticky barrier bands prevent the primary invasions of newly hatched caterpillars from egg masses found near the base of a banded tree, in surrounding leaf litter, in woodpiles, or on nearby lawn furniture. Sticky barrier bands also prevent three types of secondary invasions of gypsy moth caterpillars.
Is it too late to spray for gypsy moths?
Along Lake Huron and in eastern Ontario “the population of gypsy moth has exploded this year,” Zimmer said. Alas, most calls came too late. Aerial spraying from early May to mid-June is effective. When the caterpillars grow too large, says Zimmer, spraying is “a costly mistake.”

Spongy moth (Lymantria dispar, formerly gypsy moth) completes one generation each year. Eggs hatch in spring, typically between early and mid-May in much of Lower Michigan, and in late May or mid-June further north.

Order. The order Lepidoptera contains moths and butterflies characterized by having a complete metamorphosis; larvae transform to pupae and then metamorphose into adult moths or butterflies.
Why are gypsy moths bad?
Why are gypsy moths bad? An infestation of gypsy moth caterpillars can have a ripple effect, Petrice said. As the caterpillars spread, they affect wildlife, timber production, recreation, and the overall health of the forest. And if the population of caterpillars grows large enough, they move on from trees to other vegetation, like crops.
What do you need to know about gypsy moths?
