Spongy Moth Control

Formerly known as Gypsy Moths, Spongy Moths originated in Europe and arrived in New England in the late 1860s. Displaying insatiable appetites, they possess the ability to devour a canopy seemingly overnight, showing no preference as they feed on more than 300 species of deciduous trees and shrubs. 

Distinguishing them from Browntail Moth caterpillars, Spongy Moth caterpillars feature a unique trait: two rows of dots adorning their backs, transitioning from blue to red. While their hairs lack toxicity, they can still trigger allergic reactions in some individuals. These caterpillars emerge from their eggs between late April and mid-May, engaging in a feeding frenzy for approximately 7 weeks. By late June and July, they seek secure locations for pupation, often found between bark ridges, fissures in rocks, and even the undersides of vehicles, branches, and outdoor furniture. 

Once they transform into moths, the mating ritual begins, with females depositing single egg sacs, each containing a staggering 1000 eggs. To mitigate their impact, we strongly recommend foliar and systemic treatments during the feeding phase, primarily throughout May and June.
