Excerpt: ... Methods Used For Destroying The Gypsy Moth. The Destruction Of The Eggs. As the egg-clusters of the gypsy moth are of a conspicuous color and may be found upon trees and other objects during at least eight months of the year, the possibility of stopping the moth's increase by destroying great numbers of caterpillars in embryo becomes apparent. In each buff egg-cluster temptingly displayed upon the tree trunks during the fall, winter and spring there are from three hundred to fourteen hundred potential caterpillars. Destroy the egg-cluster and apparently you have disposed of the coming brood. You have prevented the hatching of the eggs and the consequent spreading of the caterpillars which otherwise would have scattered abroad, feeding upon nearly all kinds of trees, shrubs and garden plants. Obviously it is safer, easier and less expensive to destroy the egg-cluster in which the brood is united and stationary than to find and destroy the caterpillars after they have hatched and scattered. The destruction of eggs may not always secure extermination, as the female imago sometimes scatters fertile eggs upon the ground, and concealed egg-clusters may sometimes be overlooked. Yet persistent and thorough egg-destruction in the autumn, winter and spring may be relied upon to so reduce the number of the moths that they will do comparatively little injury in the ensuing summer. Egg-killing is recommended by many European authors as the first and chief method of preventing the ravages of the moth. Bechstein wrote in 1804: "The clusters of eggs can be looked for from the last of September or October to March, upon the trunks of trees, walls, hedges and fences, and may be crushed or knocked off into a pot and burned by kindling a fire upon them."
