"....Some require that one have a pesticide applicator's license to buy,
but others are available over the counter..."
Be reminded that some states (CA, of course, for
one) have rules that are much more restrictive than Federal rules. Almost
always your county Ag. Agent or state land grant university is a very good
source of information about what is allowed, and safe and effective in your
situation.
