Structural pest control licensing

Is your exterminator licensed in Illinois?

Search needs at least the first three letters followed by an asterisk. Results also include not-for-hire businesses (053-) and firms flagged 'No License Required', so read the license type column rather than assuming any result means a licensed contractor.

What to verify, in order

  1. 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.

  2. 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.

  3. 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.

  4. 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.
