RequiredDelaware Department of Agriculture — Pest…
Pest control is regulated by the Delaware Department of Agriculture under 3 Del. C. ch. 12, not by DPR. No one may engage in the business of applying pesticides to the lands or personal property of another without a Department license, and the business must be or employ a certified applicator at all times (§ 1206(a)). For structural pest control — General Pest Control (7A), Wood Destroying Pest Control (7B), and Fumigation (7C) — at least one certified applicator under the license must have two years of practical experience under a certified applicator within the previous three years (§ 1207(c)(1); 3 DE Admin. Code 601-5.4).
Certification requires passing closed-book exams at 70%, offered quarterly. The business license is $50 a year (or $100 biennially), commercial certification is $30 a year, and non-certified employees who handle pesticides are registered for $25 and trained. Businesses file general liability with completed operations coverage of $300,000 bodily injury per occurrence and $100,000 property damage, display the license number on service vehicles, and renew by December 31; applicators re-test annually unless they log 18 training hours over three years for 7A or 7B.
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 applicator certification are state programs of the Delaware Department of Agriculture. Local governments add only general business licensing where they require it.

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.
Delaware regulates pest control through the Department of Agriculture's pesticide program; there is no DPR pest control board.
If the business no longer employs a certified applicator with two years' experience, the Department revokes the license (§ 1209(b)(3)).

Pending verification: Whether pest control businesses also need the Division of Revenue contractor license for wood-destroying-organism repairs, or only a general business license · Department exam fees and whether the $30 certification fee is charged per category · Whether wood-destroying insect inspection reports for real estate transactions carry additional Delaware requirements (not researched)
