UNIVERSITY PARK – A printable checklist developed by Penn State Extension and the state Department of Agriculture can help citizens prevent the spread of the spotted lanternfly, an invasive insect that is threatening the agricultural, timber, and ornamental industries. The Spotted Lanternfly Checklist for Residents, now available on the extension website, contains a list of items that should be inspected before traveling. The items include vehicles, recreational or camping items, outdoor furniture, building materials, and yard and garden items. The document also features photos of the planthopper’s life stages and information on potential egg mass locations. If found, egg masses should be scraped off using a plastic card or putty knife and placed in a bag or container with rubbing alcohol. They also can be smashed or burned. Nymphs or adult spotted lanternflies can be destroyed using a fly swatter. Agriculture officials recommend having the checklist on hand for use when traveling, most notably to and from the 26 counties in the state-imposed spotted lanternfly quarantine. In our region, the quarantine includes Berks, Chester, Cumberland, Dauphin, Lancaster, Lebanon, Lehigh, Perry, Schuylkill, and York.
