California Code, Business and Professions Code - BPC § 8514.5

It is unlawful for any registered company under this chapter when billing for any subcontracted work authorized under Section 8514, to charge, bill, or otherwise solicit payment from the consumer for any structural fumigation work not actually rendered by the registered company or under its direct supervision unless the consumer, prior to authorizing the performance of the work, is provided in writing with the following statement:

“NOTICE:  The charge for service that this company subcontracts to another registered company may include the company's charges for arranging and administering such services that are in addition to the direct costs associated with paying the subcontractor.  You may accept (company name's) bid or you may contract directly with another registered company licensed to perform the work.

If you choose to contract directly with another registered company, (company name) will not in any way be responsible for any act or omission in the performance of work that you directly contract with another to perform.”
