Spittlebugs are minor pests of pines and many other plants. These insects feed on plant juices both as adults and nymphs; a heavy infestation may slow plant growth and cause distortion. Adults are inconspicuous and measure about 1/4 inch long. Nymphs, immature spittlebugs, surround themselves with a foamy white mass for protection where they feed. Where there is a heavy nymphs presence, this froth can become abundant on cones, needles and bark.

Keeping nearby areas free of herbaceous weeds, which serve as alternate spittlebug hosts, can minimize their presence on pines later.

Like aphids, mealybugs produce sugary honeydew. Providing plants with excellent cultural care and occasionally spraying them with a forceful stream of water will knock exposed pests off while also rinsing off honeydew and alleviating the dusty conditions that interfere with natural mealybug enemies. Controlling ants by making a band of sticky ant-trapping material around the pine tree trunk or placing baits in ant trails near the base of the pine will also allow natural mealybug predators and parasites to achieve greater control of the pests.
