Learn

The Bug HQ Learn hub is where working inspectors and pest control operators explain the parts of the job that are hard to find written down clearly: what a wood-destroying organism inspection actually involves, how to read the reports, and how California's SPCB rules shape the paperwork. Every guide is written from real Branch 3 field experience, not rewritten from a brochure, and each one is free to read with no sign-up.

What Is a WDO Inspection? is the plain-English starting point. It explains what WDO means, who orders an inspection and why (home buyers, mortgage lenders, and escrow during a real-estate transaction), what the inspector checks across the substructure, attic, interior, and exterior, and how California splits findings into Section 1 (active infestation or damage) and Section 2 (conducive conditions). It also covers how long an inspection typically takes and why the cost varies by company, size, and region.

How to Read a WDO Inspection Report goes deeper into the California 43M-41 code system: it walks through a real report and decodes what every number and letter means, so buyers, agents, and new inspectors can understand exactly what a report is telling them. Together the two guides take you from “what is this inspection?” to “what does my report say?”

For the software side, see WDO report software and the SPCB California WDO filing guide. More guides are added as operators ask for them.
