Licenses & Permits in Washington

General Business License

Washington State requires most businesses to obtain a Unified Business Identifier (UBI) through the Business Licensing Service (BLS) of the Department of Revenue. Washington has no state income tax, but does have a Business and Occupation (B&O) tax applied to gross receipts, which is unique among US states. Additionally, businesses must register for the B&O tax and any applicable retail sales tax. Many cities require a separate city business license endorsed onto the state license through a streamlined endorsement system.

Common Mistakes to Avoid

1
Working without a state pesticide applicator license — it's illegal and results in fines and business closure
2
Not building recurring service contracts — one-time treatments are less valuable than quarterly service agreements
3
Underestimating the value of a pest control route — a recurring book of several hundred customers at typical quarterly subscription pricing produces a substantial annualized recurring revenue base
4
Not investing in termite treatment capability — termite inspections and treatments are high-margin work
5
Skipping pollution liability insurance — a pesticide misapplication claim can exceed your general liability limits

Frequently Asked Questions

Starting a pest control business spans a wide range. A solo operator with basic equipment and a personal vehicle can launch in the low-to-mid five figures. A pest control company with a dedicated service truck, comprehensive equipment, and proper insurance requires meaningfully more — well into the mid-to-high five figures. A large multi-technician operation requires materially more capital. Use the calculator on this page to model your specific scenario.

All states require a state pesticide applicator license to legally purchase and apply restricted-use pesticides. Most states also require a pest control business license (separate from the applicator license). Requirements include passing state exams in specific pest categories (general pest, termite, fumigation). Annual continuing education is required for license renewal.

Pest control achieves healthy net profit margins for the home-services category. A solo operator with a steady recurring quarterly route generates a strong middle-class annual income from the recurring base alone, before one-time treatments add upside. After vehicle, chemicals, and insurance costs, owner net income is solid for a single-truck operation.

Top channels: direct mail to homeowners in target zip codes (low per-piece cost with steady response in the right neighborhoods), Google search ads for 'pest control near me', door-to-door sales in target neighborhoods, real estate agent relationships for pre-sale pest inspections, and referral programs paying a per-referral incentive.

Termite treatments are the highest-value single service. Bed bug treatments are the next tier of high-ticket work. Regular pest prevention contracts on a quarterly cadence are the most profitable from a recurring revenue perspective. Fumigation (tenting) for severe infestations is the highest single-job revenue. Building a diversified service menu maximizes revenue.
