The spittle bugs have returned!
The spittle bugs have returned. Soon you will start to see globs of foam on some perennials, grasses and leafy shrubs that resembles, well, spit.
Spittle bugs are the nymphs of an insect related to leafhoppers known as frog hoppers. They hatch from eggs laid in late summer that overwinter on susceptible plant stems and debris. The nymphs secrete the froth to protect themselves from predators, provide insulation from temperature extremes and to keep themselves from drying out.
The nymphs feed by sucking the plant juices. Damage to the host plant is usually negligible and the use of sprays is not warranted. Hosing off the affected plants with water is all that is needed to control them. It takes about 5 weeks for the nymphs to become adults at which time, the “spit” will disappear. Very rarely, thick infestations can cause distortion of new growth and stunting. If so, Rose Defense or Bonide 3 Rx will bring them under control.

Thank you. I was JUST out in the garden hosing off my rosemary and wondering what else I should do. Perfect timing!
ditto. I am glad to finally know what this is!
They do seem to like the rosemary... I was just wondering myself what was happening w/ our rosemary bushes. Thanks.
thanks, i had them on my strawberries, they seem to be gone
I'm waiting for them to show up on my cinereria and rosemary... so far, so good; maybe "preventative" hosing is working!?
Thanx a bunch! I always wondered about this stuff. I look forward to reading your great newsletter next month!
