Have you noticed spongy moth egg masses in your neighborhood? Last year was a boom year for spongy moth (formerly known as gypsy moth) caterpillar populations, especially in Central and Western NY. Egg masses contain 600-700 eggs each and will hatch around May. If you find them now, you can scrape them off trees or buildings and drop them into a container of detergent to prevent the eggs from hatching.
Spongy moths are non-native, but are naturalized, meaning they will always be around in our forests. They tend to spike in numbers roughly every 10-15 years but outbreaks are usually ended by natural causes such as predators and disease. Removing their egg masses is not a cure for spongy moth infestations, but it is a small step you can take to help protect trees in your neighborhood.
