Desert Museum and Emerald Sonoran Palo Verde Worms
We are new to the AZ area and for the second year in a row at this same time of year our palo verdes get their leaves eaten up by a gray looking little inch type worm. I believe eggs sacs are also on the tree because some kind of clear small beadlike things are also on the branches. The whole neighborhood has a problem with them. Is spraying the only answer? If so, what spray is recommmended?
