It is important for food-safety reasons to manage rats in school and community gardens. Rats and other wildlife can carry a number of diseases that can be deposited in the form of urine and feces on fruit, vegetables, and in the soil. Rats can also directly damage fruit and vegetables by consuming the produce entirely or by gnawing on parts of it and making it unfit for human consumption. Norway rats create burrows that can compromise beds and root systems. While rats can also chew on drip irrigation and damage the tubes, it is more common for some other wildlife species to chew on these.
Managing rodents in and around school and community gardens can be difficult. One of the easiest ways to keep many rodents at bay is to remove...
Many people this week are talking about turkeys. But not in the same way as us here at UC IPM.
Wild turkey sightings have gone from being a rare occasion to becoming a common event in recent years, as their populations have exploded in some urban areas of California. These large birds often travel together in flocks, where they cause trouble as they search for food – by scratching and digging in gardens, and leaving their waste behind. Wild turkeys often pose a traffic hazard as they cross streets or walk in roads. They can also be aggressive and may chase or harass people.
Sometimes people think it's neat to have wild turkeys around and may even encourage them by putting out food. However, did you know it is...
Domestic pigs are a familiar farm animal, but have you heard about wild pigs? These animals are destructive pests with voracious appetites and eat a wide variety of plants and animals. It's estimated wild pigs cause $1.5 billion in economic damage to agriculture and the environment in California every year!
Where Did They Come From?
Domestic pigs were released in California in 1769 to be raised for consumption. Some of these pigs were not recaptured and became feral. In the 1920's, Russian wild boars were brought to California for sport hunting. Since both types of pigs belong to the same species, they interbred. Their descendants are called wild pigs.
Why are They a Problem?

In many cities across California, urban coyote conflicts appear to be rising. Recent analysis of coyote reports from several entities in southern California has shown that coyote conflicts are generally much higher during the pup-rearing (May–August) and dispersal seasons (September–December), compared with the breeding season (January–April). It is unclear whether this is due to territoriality issues, increased human conflict due to increased coyote activity, increases in energy demands on coyotes when...

Squirrels can be problem pests in many landscapes, gardens, and structures. California is home to several species of squirrels which can be divided into three groups: tree squirrels, ground squirrels, and flying squirrels. While ground squirrels and some species of tree squirrels can be pests, flying squirrels are very elusive and not often seen and not considered.../span>
