Spotted Lanternfly Project

SLF Trap Materials

  • 1 rectangle of window screen approximately 30" x 23" (plastic-coated screen works better than wire screen). Insect screening left over from a pop-up canopy or tent works well also. Adjust the screen size to fit your tree. The idea is to have the opening of the skirt go around the trunk as far as possible to get the SLF to enter the trap.
  • 1 piece of wood approximately 11" x 1" x 0.5" (cut from wooden lath, a yardstick, or even two paint stirrers duct-taped together can work)
  • 1 piece of wood approximately 18" x 1" x 0.5"
  • 32" of sturdy but bendable wire (you can cut this from a thin coat hanger)
  • 2 plastic milk jugs
  • 1 one-gallon zip-type bag
  • Weather-proof, strong duct tape
  • 1 zip tie to attach the zip type bag to the top of the trap


The Penn State Extension, with the help of The Brentwood-Baldwin-Whitehall Shade Tree Commission, Churchview Farm, and many amazing groups and residents would like to help form an educational community Spotted Lantern Fly program. A small committee comprised of Margaret Mahoney, Jennifer Wernert of the Shade Tree Commission, and Baldwin Councilwoman Denise Maiden has been formed. The Spotted Lanterfly response will not eliminate the invasive species, but the intent of the group is to help our residents protect specific sites, such as gardens and outdoor decks that are determined to be most vulnerable.
