Tan, fuzzy patches on your oak trunks this fall could mean a caterpillar problem next spring.
Those patches are spongy moth egg masses, each holding hundreds of eggs that hatch in spring. Connecticut has seen severe outbreaks in recent years, with caterpillars stripping oaks bare across Waterbury, Watertown, and surrounding towns. Oaks are their favorite, but maples, birches, and other hardwoods common in our area are targets too.
Now through early spring is the best time to find them. Check trunks, the undersides of branches, stone walls, and even outdoor furniture. Scrape masses into a container of soapy water rather than onto the ground, where the eggs can still survive.
Oaks defoliated more than once are more vulnerable to drought and secondary pests. If you're finding lots of egg masses or noticed thin canopies this year, a closer look at tree health now helps protect those trees before spring. Early action makes a difference.
