Everywhere I have lived, bb guns were common with the neighborhood kids. When I was about eleven we lived in a subdivision and I got my first bb gun. My father made me a “shooting trap”, essentially a large rectangular box set up on its side, with a cardboard insert running from the top outside edge to the bottom inside edge. The angle of the cardboard should trap the bb when shot into it.
You want to use it to eliminate pests. They are great for that, but just be sure you know what is behind your target. You don’t have much of a chance of your ammunition passing thru your target, but if you miss you could put a hole in something you didn’t intend to. “Remember kid, you’ll shoot your eye out!”.
Also, if you are using it for anti-critter, I would suggest using pellets instead of bb’s. These tend to do a much better job at dispatching fury woodland creatures than standard bb’s. If you haven’t purchased your gun yet I would suggest that you stay away from air cartridge fired guns like the typical Daisy and opt for a pump one like the Crossman. The guns (unless they have changed dramatically since I was a kid) that use a air cartridge for propellant usually lack the power of the manual pump guns. They are more convenient, but you want eliminate to kill your prey, not injure it so it will suffer. Good Luck.
