Herbicides and insecticides are types of pesticide. I am a licenced exterminator (with structural and land licenses) and still can't spray my own lawn here in Ontario. We can only treat inside or directly on buildings, with few exceptions such as wasp/bee nests. Even though I am licensed, I would need to file an application stating where I am going to use it and say that it is for something like Poison Ivy. That is just to purchase Round-Up or something similar. If I get my hands on some Herbicide for next year, maybe I will spray before starting new plot sites, but not if I have to apply for the chemical and have the government check out my land.
Don't even get me started on the kids playing on the lawn with all the thistles and other prickly weeds. All those bored housewives who pushed for this law are now starting to regret it. On the other hand, as an exterminator who specializes inside buildings, business is getting better each year.
