Bark Lice by Ashley Grubb

Do your trees look like they’re wearing pantyhose? Don’t worry! It’s a good thing.  We have had lots of customers over the last few weeks coming in panicking that some awful insect has taken over their tree trunks and asking what to spray to kill them. There’s no need to spray. These webs are caused by beneficial insects called bark lice (they’re not really lice at all). They use the webs as a protective barrier to keep them safe from predators while they clean your trees by eating things that they don’t need,  like fungi, algae, mold, dead plant tissue, and other debris. Bark lice even devour their protective webs when they’re finished. One day you see them, and then like magic, in a few weeks they’ll disappear.
