State of Virginia regs are pretty extensive. The fish and game regs are online. Check into those before doing anything. Groundhogs are a nuisance species in Virginia but trapping regs may still apply. Check with state and local laws regarding moving any animal to another place, when messing around dens, setting traps, shooting anything anywhere for any reason. Local regs can be even more complicated than state and fish and game regs can be more complicated yet. Little things like not discharging firearms on certain days of the week, license, tags etc. can all become a problem if one does some things no matter how innocent or ignorant of any and all rules.
