I've got a ton of gray squirrels around my house . Common for me to see 10-15 at a time on my front and back lawn. They are off limits ! I consider them my " Lawn Maintenance Crew " They clean my lawn off from all the white acorns so I dont have to deal with it. Right now they work for the nuts . But if they start a " Acorn Pickers Union " I will be forced to give them a raise !
