Two new fact sheets join almost 150 home, garden and landscape pest publications in the Pest Note series that are available free both online and as PDFs at UC IPM’s Web site.

Released October 29, 2009

DAVIS, Calif. -- Just in time for Halloween, the University of California’s Statewide Integrated Pest Management Program has released two new publications offering advice on keeping bats and spiders from invading homes and bothering people.

These colorful and concise fact sheets are two of almost 150 home, garden and landscape pest publications in the Pest Note series that are available free both online and as PDFs at UC IPM’s Web site, http://www.ipm.ucdavis.edu.

The Pest Note Bats explains how to determine where bats are entering and roosting in a building, remove a bat that has flown inside a home, exclude an individual bat or a bat colony from a structure, and use outdoor bat houses in pest management. http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn74150.html

In addition to providing easy-to-follow management advice, the Pest Note Black Widow and Other Widow Spiders describes how to identify the different widow species and covers spider-bite symptoms and medical considerations. The common widow spider in California is a native species, the western black widow. The shiny black females have a characteristic red hourglass on their abdomen and a bite that can cause serious poisoning symptoms in humans. The brown widow spider recently invaded Southern California, causing substantial public concern. However, its bite is mild and is unlikely to be associated with health problems. http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn74149.html

Authors of these publications include University of California Riverside entomologist Richard Vetter for Black Widow and Other Widow Spiders and Kern County UC Cooperative Extension Advisor John Karlik and U.S. Army medical entomologist Mike Glassey for Bats.

Visit the Home and Garden section of the UC IPM Web site for more information on these home invaders as well as environmentally friendly ways to manage most other pests around your home and landscape.
