Pest Control Business Descriptions

Pest Control Business Descriptions

Structural Pest Control: Pest control related to household pests and wood destroying pests or organisms, or such other pests which may invade households or other structures. 

Companies who are licensed with the Structural Pest Control Board, a division of the State Department of Consumer Affairs, must register with the County, and will then be able to:

  • Identify infestations through inspections of the affected structure.
  • Make recommendations, estimates or bids with respect to such infestations.
  • Perform any work including the making of structural repairs or replacements, and the use of pesticides or mechanical devices for the purposes of controlling or preventing infestations. Business & Professions Code (BPC) 8505[i]

Companies that perform structural pest control must have qualified personnel who are licensed in the appropriate Branch:

Branch 1: Structural fumigations only.

Branch 2: General pests (ants, bed bugs, cockroaches, rodents, spiders etc.).

Branch 3: Wood destroying organisms (termites, powder post beetles, etc.) and perform localized treatments, but not fumigation.

Licensed Branch 3 companies perform the inspection, and will contract with a licensed Branch 1 fumigation company if they cannot address the problem with a localized treatment.  Information on termite treatments and fumigation

Agricultural Pest Control: Any type of pest control not considered to be structural.  Typical pests controlled include: insects, weeds, mollusks (snails), plant diseases, gophers, and rodents.  These pests can become problematic at a variety of different sites.

The state licensing agency, California Department of Pesticide Regulation (CDPR), provides licensing in different categories.  See CDPR’s website for a complete description of the license categories.

Agricultural Pest Control companies must register each year in every county in which they intend to advertise, solicit, or perform pest control work. 

Maintenance Gardeners:  Businesses that perform pest control incidental to their normal landscape operations must also be licensed by CDPR and register annually in any county they intend to operate.
