Plentiful rainfall in California this spring created an ideal environment for many plants to thrive, including wildflowers, trees, and shrubs that desperately needed the water. However, other potentially harmful species also benefited from the unusually wet weather. Of particular concern are poisonous plants which are growing abundantly in parks and wildlands this year. These plants pose health risks to people, especially children, and pets. Being able to identify poisonous plants and understand available control options is critical for the safety of people who encounter them. While several poisonous plants grow in California, a few of the more common are detailed below along with information on how best to remove or manage...

While sometimes beneficial, these insects can also create nests in unfavorable locations and become a nuisance around picnics and...

Many of us at UC IPM are cat lovers and owners. Cats are popular household pets that bring joy and companionship to many families. Feral cats, on the other hand, can cause problems in our communities and around our homes and gardens.
Feral cats are unsocialized, unowned cats that live outdoors. The problems they can cause are well documented. Feral cats are not treated by owners or veterinarians so they can carry contagious diseases like flea-borne typhus and rabies, and parasites like hookworm and fleas which can affect pets, humans, and other animals. Cats are also well-known hunters of songbirds and can significantly impact wildlife populations. While feral cats hunt, they do not completely control populations of house mice...

In honor of Lyme Disease Awareness Month and in response to some misinformation about ticks on social media recently, we'd like to share some tick and Lyme disease facts.
