Cuckoo Spit - Treatment And Control | Love The Garden

Cuckoo Spit

Cuckoo spit from froghoppers

Frothy masses of bubbles are often seen on a wide range of plants in summer, which can look unsightly.

Description

The 'spit' is actually a protective bubble wrapping for a small insect, called a froghopper, which sucks the plant sap and distorts the young growth of flowering plants, such as chrysanthemum, geum, rosemary and solidago. It protects the insect from attack by predators and stops it from drying out.

Symptoms

Cuckoo spit is a mass of frothy bubbles on stems of plants. Closer investigation will show the froghopper inside.

Treatment and Control

Although froghoppers rarely do much if any damage, they can be unsightly.

Spray plants with a suitable, broad spectrum insecticide. Alternatively, hose plants with a strong jet of water to wash off the hidden insects.
