Between the Fall of 2021 and the Spring of 2022, City staff removed egg masses from approximately 28,000 City trees along boulevards and within parks.  Egg masses were removed from the first 15 feet of each tree. It is not feasible to remove all egg masses from all trees and any remaining egg masses on trees that staff have visited mean they were not safely within reach of the equipment used to remove the egg masses. 

Spongy Moth is well established on both City and private trees making it impossible to remove every egg mass completely. While complete eradication is not possible, our overall objective is to reduce the Spongy Moth population and reduce the damage to our green infrastructure.
