The Formosan subterranean termite (FST), Coptotermes formosanus, is a very destructive pest first reported in California in 1992 in La Mesa, San Diego County. FST has since been found in Canyon Lake, Riverside County, Rancho Santa Fe (San Diego County) and Highland Park (Los Angeles County).
While this termite species is currently only found in a few locations in Southern California, it's important for residents and professional pest managers to be aware of them. Wood destroying pests can easily be moved through human activities.
To identify Formosan termites, UC IPM advisor Dr. Siavash Taravati and Dr. Chow-Yang Lee of UC Riverside developed this poster. Email them at starvati@ucanr.edu or chowyang.lee@ucr.edu...

It's that time of year again: termite swarm season! Western subterranean termites, Reticulitermes hesperus (species complex), produce reproductive swarms during calm sunny periods immediately following the first autumn rains. This is especially pronounced in the San Francisco Bay Area and parts of the Sacramento Valley, where mature termite colonies across a broad region may swarm simultaneously en masse, filling the air with termites fluttering their gossamer wings and filling social media discussions with wonder, horror, confusion, and dread.
Western subterranean termites may also swarm in the
While we are staying home during the pandemic, insects are most definitely not!
In fact, you may have seen different types of insects swarming over the last few weeks. Swarming is a reproductive behavior where certain insects leave their colonies in droves, mate, disperse, and establish new colonies. Most of these swarms are not successful and end up dying, but for those that are successful, spring is an optimal time for insect colonies to find new homes.
Honey bees are one type of insect that can swarm at this time of the year while looking for new nesting locations. A large number of bees may appear frightening, but most spring swarms of the European honey bee are very docile and unlikely to sting. Our

Western drywood termites (Incisitermes minor, Figure 1) are an important pest of structural wood in California, causing millions of dollars in damage annually. These termites are very cryptic, hidden in their galleries within wood members (pieces of wood), and only emerge during swarming. As a result, wood damage usually goes unnoticed for a long time.
Control options are generally categorized as either whole-structure treatment (heat treatment and fumigation) or local treatments (insecticide injection into the wood, high-power microwaves, electrocution, and other techniques).
Despite...

It's often easier to prevent pests before they become a problem than to try and get rid of them once they infest a home. While some pests can be active year-round, cooler temperatures trigger some pests to find shelter indoors.
Creatures such as rats or insects are typically looking for food, water, and shelter. Eliminate or reduce access to these resources to deter pests. There are a variety of tools that are readily available which can help block or limit a pest's entrance into the home. Here are a few suggestions to prevent creatures from stirring in your home this season.
