Saint Paul, MN Public Health Rules: Rodent Control (2026)

Chapter 334 of the Saint Paul Legislative Code regulates the business of pest control, separately from the property-owner duties in Chapter 34. Sec. 01 makes it unlawful for any person, as owner or operator, to engage in the business of pest control in the city without a Saint Paul Pest Control License, and Sec. 02 defines pest control broadly to include controlling or eliminating insects, vermin, rodents, and pest birds, expressly naming starlings, sparrows and feral pigeons, by chemicals, trapping, structural alterations, or other methods.

Sec. 04(b) requires a licensed company to keep at least one owner or operator on staff holding a Minnesota Department of Agriculture master pest control operator's license, and bars anyone from doing pest control work without a comparable state license; a journeyman-licensed operator must work under a master license holder's supervision. City employees, other government employees, and metropolitan mosquito control district staff are exempt from the city license while on official duty, though they still need state licensing to apply restricted-use pesticides, per Sec. 04(c).

Sec. 04(d) conditions the license on filing liability insurance, one hundred thousand dollars per person injured or killed, two hundred thousand dollars per accident, and ten thousand dollars for property damage, approved by the city attorney, with the license going inoperative if that policy is cancelled without a replacement filed within thirty days. Fumigation work carries its own notice regime under Sec. 05: written notice to the public health services manager, fire chief, and police chief at least twenty-four hours before fumigating any structure, posted warning signs at every entrance while the fumigant is active, and stationed watchmen until the structure is ventilated and safe. Sec. 06 folds in the federal Insecticide, Fungicide, and Rodenticide Act and Minnesota's pesticide control law by reference.
