This week school's out and houses in my neighborhood are getting

school sports or the house has a coach, but this is not the case. I
guess toilet papering a house is not vandalism, but certainly can be
classified as littering (a $50 fine, max). At one house they
spray-painted "Ha Ha " on their concrete driveway. What can be
done? What can one do to prevent their house/trees to be toilet
papered?

You can't stop 'em, you can only hope to limit the damage.

Replace the trees with water-saving models and they won't be able to
use as much toilet paper as before.
