California Real Estate Closing WDI Protocol

Mortgage underwriting guidelines across California require certified completion of the SPCB Branch 3 WDO Standard Structural Inspection Report (43M-41) prior to loan closing.

  • Inspection covers all accessible structural sill plates, floor joists, crawlspaces, and basement stem walls.
  • Mandatory disclosure of subterranean termites, drywood termites, carpenter ants, and wood-boring powderpost beetles.
  • Must be performed by an independent applicator holding SPCB Branch 3 License (Termite & Other Wood-Destroying Organisms) credentials.
The Pyrethroid Colony-Budding Diagnostic Warning

Applying over-the-counter pyrethroid sprays (Bifenthrin or Permethrin) to termite mud tubes in California triggers a defensive biological reaction called colony budding.

Repelled foraging workers retreat into separate wall framing cavities, establishing 3 to 5 secondary satellite reproductive centers. Professional non-repellent Fipronil (Termidor SC) transfers invisibly through social grooming, eliminating the central queen.
