The invasive spotted lanternfly (Lycorma delicatula) lays its eggs in masses, which often resemble splotches of mud, on tree limbs and trunks. A study in Pennsylvania finds that putting infested wood through a wood chipper effectively destroys spotted lanternfly egg masses, and researchers recommend the practice for reducing the potential spread of the pest.
