A series of two sprays is applied in early May, when caterpillars are small and most susceptible to Btk. Sprays outside of the generally infested area are applied to eliminate isolated populations of moths, thereby slowing the spread of the gypsy moth infestation through the state.
How do I get rid of European gypsy moths?
Several types of conventional insecticides can be used to control gypsy moth caterpillars on landscape trees. It is best to apply any insecticide when caterpillars are young to limit defoliation. Many conventional insecticide products are applied by spraying the host trees where the caterpillars are feeding.
What month do gypsy moth eggs hatch?
