While preparing your garden for planting this spring, you may have found white grubs in the soil. Discovering these fairly large, white grubs can be alarming, but they usually won't cause significant plant damage.
Grubs are the soil-dwelling larvae of beetles in the Scarabaeidae family, also simply called scarabs. They are generally curled in a C-shape with whitish bodies and 6 legs. Grubs of some species may be less than 0.5 inch long, while other species may be up to 2 inches. Some grubs feed on living plant material while others do not.
Masked chafer beetle grubs are often what people find in garden beds in California. If you find large grubs in compost, those are likely the larvae of the green...

Healthy Soils Week (Dec. 4-8) is a week-long initiative by the California Department of Food and Agriculture (CDFA) to highlight the importance of soil health throughout California.
Healthy soils can improve crop yields, sequester carbon, reduce erosion, and increase biodiversity. In addition, they can reduce pest problems and pesticide and fertilizer use. Healthy soils lead to healthy plants which are less susceptible to pest attacks and can better tolerate and recover from pest pressure.
In integrated pest management (IPM) we promote the use of cultural control methods to improve soil and plant health, making an environment less conducive for pests to...
Soil solarization is a method home gardeners and farmers can use to manage soilborne pests such as weeds, disease pathogens, nematodes and insects. Solarization can reduce help reduce pesticides used to control these pests.
Soil solarization is simple: prepare the site, water it a bit, then cover the soil with clear plastic for an extended period of time to allow the sun to heat the soil to temperatures lethal to a wide range of pests.
Learn more about this process in our recently updated Pest Notes: Soil Solarization for Gardens & Landscapes, by authors Jim...
If you have house or office plants and have ever seen small, dark-colored insect swarming around them, your plants could have fungus gnats.
Fungus gnats are tiny flies that as adults, resemble mosquitoes. Fungus gnats don't bite people, but their presence can be annoying. Their larval stage lives in wet, overly moist potting mix, where they feed on decaying matter.
The first step to managing fungus gnats is allowing the soil in your houseplants to dry out in between watering. To read more about how to manage this pest, visit the UC IPM publication Pest Notes: Fungus Gnats.
