Spongy Moth

Since its accidental release around 1869 in Massachusetts, the European species of spongy moth (formerly known as gypsy moth) has spread to at least 20 Eastern and Midwestern states, defoliating large tracts of forest. This invasive pest was imported in a botched effort to create silk for the textile industry.

Long Island landscapes suffered serious destruction from spongy moth caterpillars each summer for decades however efforts to control this pest (along with some lucky help from a natural virus) have improved our situation greatly. In recent years we see outbreaks in pockets- centralized “hot-spots”- with years of downturn between years of stronger infestation presence.

Should you notice this moth, its caterpillars, egg masses, or feeding damage, we still recommend our organic treatment to keep infestations in check. Inspect white oaks, their favorites, and all surrounding deciduous trees and shrubs or call us for a free inspection.
