🚐 Planning an RV adventure? Keep your travels fun and safe for our forests and outdoor spaces! ✅ Sweep out your RV interior before leaving the campsite ✅ Inspect wheel wells and the underside of your vehicle for egg masses or insects ✅ Rinse or spray your vehicle with water or compressed air to remove mud and plant material from tires and fenders ✅ #DontMoveFirewood - buy it where you burn it, use certified heat-treated firewood, or gather on site when permitted ✅ Leave any leftover firewood at the campsite or with the camp host; don’t take it home Simple steps like these help prevent the spread of invasive species and protect the places we all love to explore! #PlayCleanGo #RVCampingResponsibly #InvasiveSpeciesPrevention

If you’re in the Northeast, you’ve probably seen a spotted lanternfly this summer. The invasive species has spread to 19 states where they chow down on dozens of plants, especially grape vines.

CHECK YOUR TREE MONTH: BOX TREE MOTH - The box tree moth, Cydalima perspectalis. To date, we have not identified this pest within Indiana.
The caterpillars are ravenous feeders and will cause significant damage to ornamental boxwoods when present.

AUGUST IS CHECK YOUR TREE MONTH: ASIAN LONGHORNED BEETLE (ALB). There are two specific native beetles that are easily mistaken for ALB. The cottonwood borer and the whitespotted sawyer. See our photo comparisons. Suspicious insects can be reported at [email protected]
