Help! neighbor kids provoking my dogs.?

I have spoken with their mother about it but she said that her kids are "autistic" showing me their special badges and can't watch them all the time. (They don't live right next to my house but one after) My dogs bite and I don't want her children around them. Just the other day they put their fingers in the fence, poking them with the broom, screaming at the dogs. What shoud I do? I want to be a good neighbor.
