Keeping backyard chickens is becoming increasingly popular in residential areas around California. Your store may be selling pre-made chicken coops, feed, or other accessories, or you may be getting questions about rodent pests in chicken houses.

Inside the foamy mass you will find immature spittlebugs feeding on plant tissue. Adult spittlebugs (also called froghoppers) can also be found on the plant, and are ¼ of an inch long, and green or brown.
Although not aesthetically pleasing, occasional masses of spittlebug generally do not harm established woody plants.
The best way to deal with spittlebugs is to wash them off with water, ignore them, or handpick the bugs. Pesticides are not usually effective or needed and can cause harm to pollinators that often visit these...
Many retail nurseries and garden centers sell lady beetles for controlling aphids in gardens and landscapes. Gardeners often ask, “Does releasing lady beetles really work?
University of California research has demonstrated that lady beetle releases can effectively control aphids in a limited landscape or garden area if properly handled and applied in sufficient numbers.

If you grow roses, you might be noticing damage on the flowers caused by hoplia beetles (Hoplia callipyge). Hoplia beetles, which are common between March and May, especially in the Central Valley, feed on the blossoms of light-colored roses and other flowers in your landscape.
Hoplia beetle adults are small, reddish-brown scarab beetles that are often found resting inside a blossom. If you hold one in your hand, you'll notice that most of the body is a beautiful, iridescent silvery green color in the sunlight.
These beetles may also occasionally be found feeding on other plants with light-colored petals.
Some people believe they have the rose chafer or Japanese beetle in their landscape, however...
