As the infestation of summer’s most annoying bug continues, Montgomery County and counties across Pennsylvania declare spotted lanternfly quarantines. Keira Wingate reported the developments for USA Today.

The Keystone State currently has 34 counties in quarantine, with many of them added to the list this year. Neighboring New Jersey is also recording the spread of the invasive insect and recently added five more counties to its quarantine list, bringing the total to 13.

“The spotted lanternfly’s excellent hitchhiking skills on all types of transportation have allowed it to spread, making it necessary to expand the Lanternfly Quarantines zone,” said New Jersey Secretary of Agriculture Douglas Fisher.

The notorious insect — which is not dangerous to humans or pets but is deadly to many plants — first appeared in Pennsylvania in 2014. Because it can spread so easily, the pest quickly made its way to northeast and mid-Atlantic areas.

Residents in Lanternfly Quarantines areas are asked to look for the insect or its eggs before moving outdoor items from quarantine areas.

They are also encouraged to squash any egg masses they might find around their homes, including on trash cans, dog houses, and kiddie pools.
