Sigh. Somewhere on the bottle or bag, there's the name of the chemical used,
and the concentration, and probably a toll free number to call the manufacturer.Read carefully -- it's probably after the information on how to use that
herbicide properly, and how much to apply per square yard or meter.

If you have pets, restrict them from access to the treated property. Ditto
for your neighbor's animals, at least until you find out what you're
really dealing with.

Call or otherwise get in touch with the manufacturer and find out
what (if anything) you can do to mitigate your carelessness. Sometimes the
only thing possible is tincture of time, depending on what you put down and
how much. Don't bother to try to reseed until you've got better information.

And now you know that you have to read the instructions and apply pesticides
at the recommended rates, time of the growing season, and with the proper
growing conditions.

This is why, for most people, I only recommend a dandelion digger or mulch
for weed control.

I do hope you didn't choose something long acting and mobile in the soil,
otherwise you're going to be paying damages to the neighbors, too.
