Structural pest control licensing
Is your exterminator licensed in Missouri?
Three checks worth making. First, the REGISTERED TECHNICIAN trap: Missouri has that classification, but it does not confer independent application authority — a registered technician must work under the direct supervision of a licensed commercial applicator, so one turning up alone is a problem. Second, FINANCIAL RESPONSIBILITY: business license applicants must show an insurance certificate or surety bond, so there is something behind a claim if treatment goes wrong. Third, the GRACE PERIOD: Missouri licenses can be renewed up to sixty days after expiry, which means a license showing expired may still be in that window — check the date rather than assuming either way. Structural categories are 7A, 7B and 7C, and applicants for them must show supervised experience or a degree in biology, chemistry, agriculture or entomology. Governed by the Missouri Pesticide Use Act, RSMo ch. 281, and 2 CSR 70-20. MOPlants runs on the same platform as Pennsylvania, Montana, West Virginia, Indiana and Alabama. Bureau of Pesticide Control: (573) 751-3498.

What to verify, in order
The business license, not just the technician
Most states license the company and certify the individual separately. A certified technician working for an unlicensed business is still an unlicensed job.
The category or phase covers structural work
Licenses are issued by category. An applicator certified for turf and ornamental has no business in your bedroom.
Status is active, not lapsed
Some state databases exclude cancelled licenses from results entirely, so a revoked company returns the same empty result as a typo. If you get nothing, phone the agency before assuming you mistyped.
Complaint and enforcement history
Where a state publishes disciplinary actions they are usually on the board site rather than inside the license search.
Link last confirmed: . State license portals migrate often and licenses lapse daily — treat anything older than a few months as a starting point, not an answer.
Always confirm on the state's own site. This page points at the official database; it does not mirror or cache license records. Status changes daily and only the issuing agency is authoritative.
