What is a pesticide?

A pesticide is any substance intended to control, destroy, repel, or attract a pest. Any living organism that causes damage, economic loss, transmits or produces disease may be the target pest. Some common pesticides (and their target pests) include:

  • Insecticides (that are targeted at insects and other “bugs”)
  • Herbicides (weeds and other unwanted plants)
  • Rodenticides (mice, rats)
  • Molluscicides (snails, slugs)
  • Repellents (mosquitoes, ticks)
  • Disinfectants and sanitizers (bacteria, mildew and other microorganisms)
  • Fungicides (plant diseases, molds)
  • Wood preservatives 

What is the Agricultural Pest Detection Program (or, Why is There a Trap in My Yard)?

From March through October, the Department conducts it’s annual Agricultural Pest Detection Program (Also know as the insect trapping program). Employees of the department will deploy traps that target seven different pests: Mediterranean Fruit Fly, Oriental Fruit Fly, Melon Fly, Glassy Winged Sharpshooter, Japanese Beetle, Gypsy Moth, and Light Brown Apple Moth.

Pest detection traps are rotated throughout the county to ensure full coverage. When traps are placed on private property, the trapper asks permission of the owner and if the owner is not available, a notice is left at the door. The cooperation of the public is necessary and appreciated in this effort to ensure a successful detection program.

"As non-native pests can damage a wide variety of fruits, vegetables, and ornamental plants in nurseries, on farms, and in home gardens, timely detection is vital," said Yolo County Agriculture Commissioner John Young. "If no target pests are found, the county can be certified as pest-free which enables exportation of produce and plants which is vital to our economy."

What do I do if there is a bee swarm in my yard?

Please contact the Agriculture Department at (530) 666-8140 during normal business hours and we will provide you with a list of Beekeepers who will come out and capture the bees.  Please do not try to catch the bees yourself, the beekeepers are trained professionals.  Please do not attempt to kill the bees, they are a beneficial insect and necessary to the pollination process.
