Yes. Pesticide and herbicide applicators often must be licensed, although the details all depend on your jurisdiction. Check with state and local agencies and figure out who must be licensed and make a complaint.

A very easy google search pulls up the info.

Compost him.

And once you find out where to report him, report him at least once for every address you see him at. That should get the neighbors involved, because they should be contacted by the licensing agency.

Thank you so much for that link!!! I already made a complaint agaist him. I'll get a phone call tomorrow and know more. I think I might take the kids and go for a walk and write addresses down where I see little orange fertilizer balls. I hope my neighbors don't get mad, but the man they hire shouldn't be going around town spreading it all over the streets!!

If it doesn't help to talk to the guy who does the stuff, maybe he has a boss? Call the company (should be obvious from seeing his vehicle or whatever) and complain that they are poisoning your yard, and that if they don't take steps to avoid this in the future you will take legal action. You don't really have to sue them or anything, a nice threat should help. But wanton spraying of chemicals must be some kind of crime. (should be, anyway) If it isn't a crime, spray the man with vinegar or something and see how he likes it!

I have a good friend who had her lawn accidentally sprayed by Chem-Lawn on at least one occasion. It killed all her daffodils. They mistook her house for another one on a nearby street, same house number, slightly different street name. Of course she also got a free new driveway because of the same confusion.

So glad I live where I live!! Our municipality adopted a 'green' policy a few years back and it works. Landscapers, hesitantly but successfully, learned to make a buck without expensive poisons.

I remember one day reading in the newspaper about 4 families having to move out of their homes for a few days because some members would get sick from one neighbour's property where the lawn was being treated with herbcides/fertilizers/etc.

This doesn't happen anymore.

I hope you meet with success as you should!

Maybe also talk to your neighbors about organic gardening and see if they would be interested in making the switch. I have a neighbor that uses the chemical junk and I have talked to her about the health risks of the chemicals and also am trying to be an example that organic really is better. I am hoping that over time through my example and my garden being healthy they might consider doing things different. There is alot of people I found that do not know about organic. I used chemicals until I found out the benifits. Plus some also I have found are tired of the activism over the earth so they resist at the expence of their health at times. I consider that to and have had one who was sick of the activism and resisted, reconsider because she knew the truth about health benifits rather than the controling radical activism. Maybe with that in mind, talk about it. Tell how much money you save, the health benifits and why it is your passion. they might reconsider when they have more info on it. Might not happen all at once, but it will put a new light on why you do what you do and they will be more watching your example in a relaxed comparison.

Why are there smoking bans and strict regulations all over the place, but none for lawn chemicals, which can be just as toxic? Most likely because there is power in numbers, and the nonsmokers finally got fed up. Organic gardeners can do the same. Get neighbors to sign petitions and take it to your town hall. Set up a neighborhood meeting, and give them statistics and facts on how harmful the chronic use of these chemicals are. It takes years and years to make changes, but all change starts with one step.

If I were you, I'd tell him directly and firmly that he is not to spray on windy days. I've done that. Neighbors probably don't know what the word "organic" means. Guy came one day and was applying whatever; it was windy. I went over, told him the wind was in my direction, and that I insisted he stop immediately. So he did. What'd he care? He was a salaried employee of the lawn service company.

And while you're at it, tell him you'll report him the next time you find anything on your driveway. Who knows? He might believe you!

You might check with the EPA:

It seems like I read somewhere that there are federal regulations against fertilizer/pesticide drift.

Thank you to all that has responded. I'm so glad that there is other organic believer out there, I wish there were more in my small town. I'm still waiting on the phone call back, I'm not sure what usually happens on complaints. I'm interested to know how it will be handled.
The man who does the work is an older man who does it himself for a retirement job. One comment he yelled to me last month when I chode him out for spraying the herbicide on a breezy day was "...you just don't understand that I have to make a living too." Thinking back on that comment he made makes me sick, that money is that important to him that he doesn't care what he's doing or who he is hurting. His priorty is to get as many customers as he can and go and get it done as fast as he can while being as careless as he wants to be... While not noting property lines, wind(even a little breeze carries that stuff) and run off to the street, even people, children, and pets in the next yard, etc...
I hope I'm not known as a trouble maker. I love my neighbors, but the man they hire needs to be serious and responsible about what he does. While I might have a few more weeds then some people, I 'm okay with it. My husband is a Master Gardener and it doesn't hurt his pride a bit- we just keep the mower blade a little raised and it really helps. My grass is greener already, and wait another month when their grass will get burnt by that stuff when the temprature raises, lol. I'll enjoy my green, natural grass a bit longer(weeds and all).
Hopefully I'll have an update tomorrow when I hear a follow up on my complaint.

next time you see him you could offer to show him how to do it properly preferably while some of his customers are around point out all his faults in a calm manner while smiling intensely at him and offer to give him some more gardening advice maybe you can embarress him in to being a bit more carful and if he does take you up on it convert him

I think you are being a little too delicate with this issue. There are most certainly laws concerning pesticide applications in place and anyone who applies them as a commercial business MUST be licensed. Part of the licensing procedure is testing for an understanding of how and when to apply them correctly so as to minimize drift and contamination of other properties. Failure to do so can result in substantial fines and loss of license. I doubt licensing is much of a interest with this yo-yo, but he appears to be motivated by $$, so the possibilites of some rather heavy fines should get his attention quickly. Contact your local Ag department - they are most often the ones responsible for these types of regulations and if necessary, will direct you to someone locally.

It is all very well and good to attempt to educate both your neighbors and whomever they hire, but the bottom line comes down to these chemicals ARE regulated for a reason and just as the pesticide label is a legal document with regulations and rules governing its usage, what your neighbor's "worker" is doing IS illegal, fineable and possibly prosecutable.
