One of the best ways to reduce pest problems in and around buildings is to construct or retrofit structures that keep pests out in the first place. This concept has been a pillar of integrated pest management for many years. Pest-resistant buildings reduce not only pest problems but also the need for pesticide applications. Unfortunately, architects and builders had few guidelines about how to design and construct such structures.
To address this issue, the San Francisco Department of the Environment and the International Code Council developed an online publication, Pest Prevention by Design, which provides the first comprehensive resource on pest-preventive building design tactics.
Specific guidelines are...
Every spring, we see pictures and artwork of adorable Easter bunnies-- cute, little rabbits that deliver gifts of chocolate and other goodies to our children.
However, while “bunny rabbits” are cute, rabbits can also be very destructive pests year-round in the garden and landscape. This is especially true if your home is near wild or uncultivated lands, parks, or greenbelts. These places provide resting and hiding cover during the day for rabbits.
Rabbits can damage ornamental plants, vegetable plants, herbs, trees, and berry crops. They also gnaw and cut plastic irrigation lines, especially small diameter tubes.
There are eight species of rabbits found in California. Three of them are widespread and...
The brown marmorated stink bug (Halyomorpha halys) or BMSB is a new invasive pest of urban and suburban homes and landscapes in California.

Bed bug encounters are on the rise throughout the United States and no hotel is completely immune to potential infestations. Unfortunately, Mr. Irving didn't know about checking for bed bugs in his hotel room before settling in.
Don't let this happen to you! Watch UC IPM's short video on how to inspect your hotel room for bed bugs.

Today's post for National Invasive Species Week highlights two ambrosia beetles that are detrimental to certain trees. Ambrosia beetles are highly specialized beetles that excavate tunnels in usually weakened or dead trees and cultivate fungal gardens, which they feed upon. Below are two such invasive beetle-fungal complexes that are currently impacting trees and forests in California.
Walnut twig beetle and thousand cankers disease. Walnut twig beetle, Pityophthorus juglandis, is a tiny bark beetle that attacks only walnut trees. The beetle has been in California for many decades but recently became associated with a new fungus, Geosmithia morbida. The fungus kills the phloem and cambium of...
