What is Armillaria Root Rot?
Armillaria root rot is a severe fungal disease that affects trees, woody plants, and some herbaceous plants including palms and succulents.
Also known as oak root fungus, Armillaria root rot can rapidly kill trees and presents a challenge to management since infected woody roots can persist for years underground. No plants are completely immune to Armillaria root rot, so prevention is key. Deeply planted trees are often more susceptible to this disease.
The distinctive “honey mushrooms” growing from the base of a tree signals an infection, but they may not always be present. Other visible symptoms include flat cankers on the trunk, wilting, and canopy.../h2>

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.
Trapping is the safest and most effective method for controlling rats and mice in and around homes, garages, and other structures. Rodents that live in close association with humans are called commensal rodents. Rats and mice are the most frequently encountered commensal rodents in California.
Selecting the correct trap
Before trapping, make sure you know what rodent pest you have. It is a very common mistake to select the wrong size trap when you have not yet determined whether you have mice or rats (and the correctly identified rat species).
You will not catch a rat with a mouse trap, and you will not catch a mouse with a rat trap. To determine.../h2>

At some point, all of us encounter a pest in our home, garden, or landscape. But you're not alone! UC IPM publishes Pest Notes – a series of more than 150 papers reviewed by experts in the field – to provide science-based information about pests and their management.
These ten Pest Notes were the most frequently viewed online in 2019, with more than 330,000 total pageviews. While it's not a contest, we like to think these are the winners of 2019's most popular pests.
These small, soft-bodied insects can multiply rapidly, especially in warm weather. Many species exist in.../h2>
