Spittlebug

No, the neighborhood kids have not been spitting in your garden. The spittlebug, also known as the froghopper, is the culprit. 

These insects suck plant juices and secrete the excess as a clear substance. As it does this, the spittlebug uses its hind legs as a bellows to cause the secretion to form a bubbly mass that looks like spit. This helps prevent desiccation and hides the insects from predators. Spittlebugs are usually found in the leaf axil near the stem.

They are usually small in number so control is not needed. Some types of spittlebugs serve as a vector carrying disease from sick to healthy plants. But even this does not usually warrant control.

You can use a strong blast of water to dislodge these insects from the plants. Or remove the infected branch. The next step is insecticidal soap. Use natural products to avoid killing the natural predators and parasites that help control these pests.

A bit more information: Gather the kids and do a little detective work. Remove the bubbly mass from the plant and look for the insect below. With the help of a hand lens you will easily see the source.
