Wisconsin regulates pest control through the Department of Agriculture, Trade and Consumer Protection (DATCP). Three credentials stack: the business license (Wis. Stat. § 94.703, $90/year per location, $115 with bulk pesticides), an individual commercial applicator license for each applicator (§ 94.704, $50/year), and certification in the right category (§ 94.705, five years).
For structural work the core category is ATCP 29.31(11) — Industrial, Institutional, Structural, and Health-related Pest Control — with Fumigation split out as its own category (12). Licenses run January 1–December 31; certification is earned by exam and lasts five years.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Pesticide licensing and certification are statewide through DATCP; no local credential substitutes. Local business rules where the company is based still apply.
The local offices section below names the exact permit desk for every Wisconsin county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
Both business and applicator licenses expire December 31 every year regardless of when issued.
Certification (5 years), applicator license (annual), and business license (annual) must all be in place before the first for-hire application.
Fumigant work needs Category 12 certification on top of structural Category 11.
