If you don't you'll wish you did.

Somebody has a catchphrase on here says, “I’m paranoid but am I paranoid enough?”

You know better than anyone here if you should set a few. Why ask a bunch of us meatheads? Lol

Your over thinking and under thinking this thing, mother decides more about “seeds” then we do. Trap and sell is not your only option think about trap and tan ot other markets out there.

get out there and enjoy yourself , and post some pic,

As long as you aren't trapping California condors or black-footed ferrets, you won't hurt a thing. Plenty of fur bearing seeds out there.
Besides that, if population density is maxed out, thinning the herd will result in bigger litters from the remaining animals.
