Artjak, Weedkiller is potentially more dangerous than pesticide (having had a brother in law who died from weedkiller poisoning 30 years ago it's something I know about only too well). OK weedkiller formulas have changed over the years and what you can buy in the Garden Centre is totally different to that which was available 30 years ago, but what is available to professionals and commercial people today may be a whole different issue, and what comes over into a residential area (accidentally or carelessly) may be another matter. I would certainly follow it up, but, as 'Dove' says, it may not serve you best to go in with all guns blazing.
I would ask first what chemicals were used in the spraying?, can he/they supply you with a copy of the COSHH details relating specifically to the chemicals used? who carried out the work? is it likely to happen again and if so when? and what safeguards has he/they put in place to protect third parties and their property?. This will do a number of things: 1). It will demonstrate you have very real concerns over what happened, not just as a matter of inconvenience but on H&S grounds. 2). It will show you are asking reasonable questions, 3). That you expect reasonable answers: 4). that you are prepared to investigate the Health & Safety issues relating to the product he/they used. It may also pay to ask for a copy of their 3rd party liability insurance. Every business is legally obliged to have this and it will indicate you are sufficiently aware of his obligations and are prepared to follow through with legal representation if he/they refuse to comply. Hope this helps. John H
