Pest Detection Trapping Program

Every year our staff places and inspects over 6,000 insect detection traps on selected residential and commercial properties throughout the county. When a target pest is found, immediate steps are taken to control or eradicate the population.

What you can do to help

Public participation is critical to the success of this program, since staff rely on the goodwill of those who allow traps to be placed on their properties. Traps are placed free of charge and monitored regularly. Trap inspection normally only takes a few minutes and can usually be done without disruption to the resident/business. Property occupants are not restricted in the use or care of their fruit trees, garden or lawn while traps are present. 

Residential properties with fruit trees are ideal trapping locations. Other plants of use to the trapping program include roses, turf and some select landscape ornamental plants. If you interested in having traps placed on your property to help in the fight against pests, contact us at agcommissioner@ag.cccounty.us or call us at (925) 608-6600.
