They may seem too tiny to do much damage to a mature, healthy tree, but invasive shothole borers (ISHB) are responsible for the deaths of tens of thousands of trees in Southern California. These beetles bore into trees and infect them with Fusarium dieback, a fungal disease that kills the trees. Many native California trees like California sycamore, valley oak, and arroyo willow can be killed when invasive shothole borers attack them.
While these pests are currently only found in Southern California, they could spread to many other parts of the state. Limiting the infestation will reduce their impact. Controlling the beetles is difficult but includes regular monitoring of trees to quickly identify sources of...
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...

Voles are small, mouselike rodents that can be pests in gardens and landscapes. They damage many types of plants with their gnawing, from vegetables to turf to trees. Voles can gnaw completely around the trunk or roots of trees, causing girdling, which can kill trees.
Voles spend most of their time below ground in their burrows, but you can spot their presence by the well-traveled runways connecting the burrow openings. They prefer not to feed in the open to keep away from predators.
Voles are normally found in areas with dense vegetation, so clearing brush is one way to discourage them. Find out more about managing these rodents in the newly updated
With many people thinking about turkey this time of year, we thought we would provide some interesting facts about wild turkeys for you to share during your holiday gatherings!
- Turkeys are not native to California but were introduced by European settlers. Most turkeys we eat are raised on farms but there are millions of turkeys that roam wild. The population of wild turkeys in California is estimated today to be roughly a quarter million birds!
- Turkeys are polygamous, meaning they will have more than one mate. They breed in...

Ripe, juicy, sweet blackberries: what's not to love? Blackberries are grown for us to eat and enjoy, but some species can be considered weeds when they take over home landscapes, roadsides and waterways, and other areas. The most problematic species are the introduced wild blackberries, cutleaf blackberry and Himalayan blackberry. Blackberries can be highly competitive, smothering existing plants with their dense stands. Accumulation of dead stems can create a dangerous fire hazard.
In urban landscapes, blackberry brambles can create habitat and food for wildlife and birds, but also for rats and other pests. When invasive wild blackberries take over a...
