A cornerstone of chemical lawn care marketing is the claim that service personnel are "Licensed" or "Certified" in lawn care.

Here's is the trick to finding out if your service-person really has a lawn care license: If the license begins with an "O" and/or has 5 numbers, it's the general pesticide certificate, not a Lawn license. But it begins with an "S" and/or has 4 numbers, it's a lawn (or tree) professional.
