Are the squirrels in my yard going to die if we stop feeding them?

Actually, they could start to die off. When you feed wild animals (especially foragers like squirrels) they ecome dependant on you for food. They know where to find it and will continue tocome back whether the corn is there or not. if money is that tight, wean the squirrels off gradually... Put a half corn cob in there a day for a week and then a half every other day the next and so on and so forth. They'll start looking for food elsewhere.
