Isn’t spittlebug a great name?
Spittlebugs are easy to spot when in their immature phase because the nymphs surround themselves with a white froth when they feed, hence the name. Adult spittlebugs are only 1/4” long, unremarkable and rarely seen. And, no, they won’t hawk a loogy at you in the garden.
Spittlebugs suck the juices out of your plants but they rarely do any serious damage. Since so many woody California plants are currently under drought stress, any help we can give to keep them hydrated and healthy is a good idea.
If you see splotches of white foam on your plants (I found some this morning on my rosemary and lavender), simply wash them off the plant with a hose. This interrupts the spittlebug lifecycle and protects your landscape.
