Pest Detection

The Pest Detection Program attempts to locate harmful plant pest infestations in their early stages before they become too extensive to be eradicated.

The Alameda County Department of Agriculture maintains a continuous Pest Detection Program. This is part of a statewide program to protect California's agriculture from unwanted exotic pests.

Trapping represents the second line of defense in California's Pest Prevention System. Each year, Agriculture Inspectors place and monitor over 7,000 insect survey traps in Alameda County. These traps are strategically placed in residential, commercial, and park properties where adequate hosts are available.

Alameda County Agriculture Inspectors are currently trapping for the following exotic pests:
