Oklahoma is one of the few states that will not accept a plain certificate of insurance. The Department of Agriculture, Food and Forestry has its own certificate form for pesticide applicators, and it asks for things an ordinary ACORD certificate does not carry. The policy has to respond to damage, loss or injury including chemical drift or trespass. The deductible may not exceed $5,000 for the total amount of liability insurance. The insurer has to agree to give written notice if the policy is canceled before its expiration date. Miss any of those and the filing comes back, no matter what the limits say.
The limits themselves are modest. For ground applicators the form requires $50,000 bodily injury per individual, $100,000 bodily injury per occurrence, and $50,000 property damage. Aerial applicators file at $100,000 per individual, $300,000 per occurrence and $100,000 property damage. Read the exception carefully, because it does real work: the required coverage does not have to extend to the agricultural crops, plants or land actually being worked upon by the applicator. The state is protecting the neighbor, not your customer's field.
Then there is the renewal schedule, which trips up more Oklahoma operators than any limit ever has. Commercial licenses run on a split year set by the first character of the company name. Names beginning with a symbol or the letters A through L run October 1 to September 30. Names beginning M through Z run January 1 to December 31. Buy a company, change a name, and the license year can move underneath you. While you are pulling your certificate, put the company on BestPestControlIn.com. Listing is free for any licensed pest control company, Oklahoma homeowners search it by ZIP code and by state, the listing carries a backlink that helps your own site rank, it sends referrals, and we write blog posts on the companies in the directory.
