Circle Trap for Catching Spotted Lanternfly June 20, 2023 by tracey Learn how to make your own Lanternfly Trap. First and second instar nymphs (black with white spots… about 1/8″ long) are now active in the landscape, and we are starting to catch them in the circle traps installed on a few trees in the garden. We are targeting trees that were observed to have high populations last year. This week our incredible high school horticulture interns helped put together a dozen more traps with Laura’s guidance. If you’d like to make your own, we’ve put together a materials list and instructional video for you to follow along. Let us know if you have any questions in the comments below.
