Michigan licenses commercial pest control firms through the Michigan Department of Agriculture and Rural Development (MDARD). Every pesticide application business license application has to include a certificate of liability insurance, and the coverage has to stay in force for the whole license period or the season you operate.
Michigan's rule has one feature that matters more than the dollar amounts: the comprehensive general liability insurance cannot exclude bodily injury and property damage that arise from pesticide applications. As an independent insurance agency working with pest control companies, Reasons Insurance can help you check that your policy does not quietly carve out the work your license is for.

Rule 14 says the required liability insurance shall not exclude coverage for bodily injury and property damage that arise from pesticide applications. A general contractor's form or a pollution exclusion written broadly enough to reach your chemicals can fall short of that rule, so we read the exclusions, not just the limits.
Space fumigation, aerial application and right-of-way pest management carry their own minimums in Rule 14: $100,000 bodily injury and $25,000 property damage per occurrence, or a $300,000 combined single limit. If you hold categories with different minimums, the greater requirement applies to the whole license.
If the required insurance expires or is canceled during the license period, Rule 14 says the license is suspended and surrendered to the director until the requirement is met. A missed renewal can stop your trucks, not just raise a question on a certificate.
Rule 12 requires the license application to include a certificate from an insurance company, or an approved surplus lines company, authorized to do business in Michigan. The certificate has to show the limits in Rule 14 and be in effect for the entire license period or for the period in which your applications generally occur. Seasonal operators, such as mosquito or lawn firms, should make sure the policy term actually spans their season.
A single comprehensive general liability policy can cover more than one licensed place of business owned and operated by the same person. If you run branches in Grand Rapids and Lansing under one owner, one policy can satisfy the rule for both, as long as each location's work is described accurately.
A $25,000 property damage limit per occurrence is low compared with the cost of a single water-damaged condo unit or a contaminated commercial kitchen. Property managers, school districts and health care facilities often ask for much higher limits, additional insured status and primary wording in their contracts. We compare those contract requirements with your policy, not just with the state rule.
Check how your policy treats completed operations, too. A complaint about a treatment that shows up weeks after the job is done may depend on whether products-completed operations coverage is included and how its aggregate works.
MDARD's business page notes that most pesticide applications in schools, public buildings and health care facilities require the applicator to have completed an approved integrated pest management training program, and the building needs a verifiable IPM program. These accounts also tend to have the strictest insurance requirements in their service contracts, so keep training records and certificates of insurance in the same file.
MDARD asks sole proprietors and partnerships for a DBA certificate in each county where the firm operates, and corporations and LLCs for their corporation ID and any assumed names. The applicant must be a certified applicator or employ one whose credentials cover the categories applied for, and every employee who applies pesticides must be a certified applicator or registered technician. Make sure the named insured on your policy matches the legal and assumed names on file.
If you already carry coverage in Michigan, the Pest Control Insurance Friction Check walks you through the questions that tend to cause trouble at a certificate request, a renewal or a claim. It takes a few minutes and you can bring the results to a review.

For most license categories, Mich. Admin. Code R 285.636.14 requires at least $100,000 per occurrence for bodily injury and $25,000 per occurrence for property damage. These are licensing minimums, not a recommendation for your company.
Yes. Aerial application, space fumigation and right-of-way pest management require $100,000 bodily injury and $25,000 property damage per occurrence, or a $300,000 combined single limit. If you hold categories with different minimums, the greater requirement applies.
