Have you seen big green beetles in your California yard or garden? Or beetles feeding on your roses or other plants? There are many kinds of beetles commonly found in our landscapes, but the Japanese beetle is not one of them.
Many people think they've seen the Japanese beetle, a small scarab beetle with metallic green wings with white spots on the margins. However, Japanese beetles are generally not found in California.
The Japanese beetle is an exotic and potentially invasive pest for which the California Department of Food and Agriculture (CDFA) is conducting eradication efforts to limit its spread.../h2>
When you see spiders in your garden, you may wonder if they can hurt you or your pets. The good news is, most spiders are not likely to bite or cause lasting harm if they do. Plus, they provide natural pest control! Here are a few spiders commonly found in gardens and landscapes:

Several Assembly Bills (AB 2596, AB 1687, and AB 2422) have been introduced proposing either bans or major restrictions on rodenticide applications.
Anticoagulant rodenticides have been detected in many species of wildlife worldwide; yet the origins, exposure pathways, and effects of these exposures are not well understood. The origins of these rodenticide exposures from point of application to point of...

“I hate crabgrass!” is a common lament I've heard from residents during my 35 years as a UCCE Weed Science Farm Advisor. However, four out of five times, the weed people are actually referring to is not crabgrass, but bermudagrass or dallisgrass. So why does knowing the name of the weed matter?
