I'd don my brightest shiniest Marigolds, pick it up and make sure they see you (better still the parents see you) when you throw it back, then ask them very politely (very very obviously politely) to try very very HARD not to kick the ball into your garden because that is how infection spreads infection spreads.
As a matter if interest - do the neighbours on their other side have the same problem?

Passports not in the drawer I always keep them in. Turning the place upside down.
