Gypsy moth caterpillars are eating leaves; here’s what to do
Michigan Department of Natural Resources forest health experts are getting reports of oak, aspen and maple trees losing leaves to gypsy moths in the southwestern and northeastern parts of the Lower Peninsula.
The gypsy moth is an invasive species that caused widespread defoliation in the state from the mid-1980s to the early 1990s. This year, defoliation is likely to become visible within the next few weeks in localized outbreak areas and persist through mid-July.
“Gypsy moths are a nuisance but rarely kill trees,” said Scott Lint, forest health expert with the DNR’s Forest Resources Division.
Keep defoliated trees healthy by making sure they get water; avoid damaging tree roots and bark. Trees should begin to develop new leaves in July to replace those that were eaten.
