Pecan Spittlebug – Identification
Q: I have notice a white wad of foam around the stem where my pecans are growing,;what’s going on?
A: The foam is caused by pecan spittlebug nymphs. This has been a good year for spittlebugs of all kinds due to frequent rain and high humidity. The nymphs suck sap from the pecan stem and cover themselves with froth to protect themselves from predators. The good news is that they do little damage. You can use a blast of water to wash out the ones you can reach and can then forget about the rest.
