Agriculture / Weights and Measures

Over the counter pesticides sold directly to homeowners such as the ones you buy in retail neighborhood hardware stores do not require a permit or any special licensing to purchase or use. A restricted materials permit from the County of San Luis Obispo Department of Agriculture/Weights and Measures is required to purchase, use, and store restricted pesticides. Certification is required to use these pesticides. You can be certified either by obtaining the Qualified Applicator License (QAL) or the Qualified Applicator Certificate (QAC) which are issued by the Department of Pesticide Regulation (DPR) or by examination at the County of San Luis Obispo Department of Agriculture/Weights and Measures Office for a Private Applicator Certificate (PAC). The PAC is only for people that apply restricted pesticides to their own property. Information on the PAC license and a list of restricted use pesticides can be obtained by calling the County of San Luis Obispo Department of Agriculture/Weights and Measures at (805) 781-5910, or by visiting the California Department of Pesticide Regulation’s website. Restricted use pesticides and pesticides that only give per acre instructions are not intended for homeowner use. Special licensing is required to perform pest control as part of your business on properties other that your own.

All pesticides are poisons. Some are more toxic than others. All labels utilize a signal word, which gives you a general indication of the level of toxicity. The least toxic pesticide is CAUTION, then WARNING, then DANGER. If you choose to use a pesticide, read the label very carefully and follow all of the instructions. If you want more information about toxicity or health effects of a pesticide you can call the Poison Control Center at (800) 876-4766 or the National Pesticide Information Center at (800) 858-7378, or check the following websites http://www.cdpr.ca.gov/ or http://npic.orst.edu

The Fumigation company will provide a list of things that must be done.

Pesticides are agents used to control pests such as insects, weeds, fungus, or rodents. To identify whether a household chemical is a pesticide, look at the product label affixed to the container. All pesticide labels contain what is known as EPA Registration Number (EPA Reg. No.).

If you plan to do agricultural pest control work as a part of your business, there are two types of licenses: The Maintenance Gardener Business License is for people who perform pest control incidental to their gardening business. Prior to applying for the business license, you must obtain a Qualified Applicator Certificate (QAC) in the maintenance gardener category (Category Q). The Pest Control Business (PCB) License is required for any person who engages in the business of providing pest control. A Qualified Applicator License (QAL) is required in order to apply for the PCB License. The Department of Pesticide Regulation (DPR) administers the exams for both QAC and QAL. The Business Licenses are also issued by DPR. For further information, you may call the licensing branch at (916) 445-4038 or visit www.cdpr.ca.gov. You can also hire a QAL to qualify your business for a state license.
