In Indiana, pest control businesses are licensed by the Office of Indiana State Chemist (OISC) at Purdue University. Before OISC issues a business license, every for-hire pesticide application business and every Category 12 wood-destroying pest inspection business has to prove financial responsibility with liability insurance.
The Indiana rule reads simply, a $300,000 combined single limit, but the details trip companies up: the policy has to carry the business name exactly as it appears on the license, the proof must come from the insurance company, and it has to be refreshed every time a policy on file expires. As an independent insurance agency working with pest control companies, Reasons Insurance can help you keep those pieces lined up.

OISC says the policy must be issued in the name of the business as it appears on the license. If you trade under a DBA, recently incorporated or bought another company, the named insured on your policy may no longer match. We check that line before anything else.
The certificate has to come from the issuing insurance company, and updated proof is due whenever a policy on file expires. A renewal that is bound but never reported to OISC can still leave your license file out of date, so ask us to help confirm OISC received the renewal certificate.
Category 12 wood-destroying pest inspection businesses need a $300,000 combined single limit for property damage. An inspection mistake, though, is usually an errors and omissions question, not a general liability one, so we can help you review how a policy treats inspection errors; the policy and the insurer decide coverage.
OISC asks for proof before a license is issued, and the proof has to be liability insurance meeting its standards. For pesticide application businesses that means general liability with at least a $300,000 combined single limit covering bodily injury and property damage. A combined single limit is one amount available for a single occurrence, whatever mix of injury and damage it involves.
OISC may be named as the certificate holder on your certificate of insurance. Because insurance has to be kept current, the renewal date of your policy effectively becomes a license date too. OISC warns that failing to keep valid proof on file may delay or deny your business license.
The state minimum tells you what a license requires, not what a claim might cost. A misapplied product in a restaurant kitchen, drift onto a neighbor's garden or a slip on a freshly treated floor can each involve both injury and property damage, and they all draw on the same combined limit. Commercial customers and property managers often ask for higher limits, additional insured status or a waiver of subrogation, and we review those contract terms next to the state rule.
Also check how your policy treats property in your care, custody or control. Many general liability forms exclude damage to the part of a building you are working on, which is where a treatment complaint usually starts.
A wood-destroying pest inspection for a real estate sale is a written opinion a buyer and lender may rely on. Indiana ties the Category 12 license to a property damage limit, but a missed infestation found after closing is typically alleged as a professional error. We can help you review errors and omissions options for inspection work and how they respond to a claim made after the report date.
OISC also publishes resources on applicator supervision, business recordkeeping and mandatory annual training for non-certified applicators. Good records are often the first thing an adjuster asks for after a complaint, so keeping application records organized helps both your license file and any claim.
If you already carry coverage in Indiana, 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.
