Eye protection is a must, actually pellets would be a better choice if you shoot indoors since there is less chance of a ricochet.
Always treat a gun as if it were loaded and stress that to your boys.
BB guns are real guns too.
You could make a BB trap yourself instead of buying one if you want, we did when we were kids, it's easy with some tools and some wood.
good luck and don't shoot your eye out.
