Spotted a weird, flat-headed worm in your yard? That’s a hammerhead worm, and it’s bad news for earthworms and gardens. These toxic invaders are spreading across the U.S., and squishing or cutting them just makes things worse—they multiply! Instead, bag and freeze them or drown them in soapy water. And definitely report any sightings. Who knew yard work could get this wild? #Science #invasivespecies #gardening
