Personal Disclaimer:The Law is the Law and I do not make the laws. I only try to learn the laws so I can operate within those laws and their LOOP HOLES. If you apply illegally with out a license, you are in fact stealing work from all those who Paid their dues and have a License. Under Chapter 482 of Florida Statues you must post a sign of any Pesticide application either at the site of a spot application or at the Main Entrance to the property. The standard sign should also include the Name of the Company, their Phone Number and Date of application. I have seen those signs stay in a yard for months, especially in the winter when very little mowing is done. AS for test, At one time I was a CEU provider and taught that class back when it was 8 hours long. Bottom line is it is a Compromise license that was started to keep people legal to spray Roundup. The test is geared for County Employees to pass as well as every other fools. Anyone who fails that test shouldn't be spraying and should get in line for the Darwin Awards. It is the same as being Licensed it Corn Crib Iowa. You don't have to know any thing.
