Spittlebugs are usually found on plant stems where they cover themselves in a
white, frothy substance for protection from predators When the spittle is removed, the small green larvae can be seen. They are less than 10 mm long and look similar to leafhoppers.The adults also look like leaf hoppers and are 12 mm long .
There are usually not enough spittle bugs on any one plant to
cause much injury, however, extensive feeding by spittle bugs can cause yellowing or stunt plant growth.
Generally there is no control needed, however, the bugs may be removed by hand, or with a strong flow of water, or the infested area can be pruned out and destroyed. Healthy plants have minimal pest problems. Inspect
transplants for insects before purchase.
Selecting varieties that are well adapted to the low desert, place them in appropriate locations to provide adequate space and light, provide proper
fertilization, irrigation and insects will rarely be a problem.
