For feeding squirrels?  I don’t think that’s a good idea.  Squirrels will just leave the corn for mice to eat, and then the mice will return to your house.  Maybe you can try this experiment:  Remove the corn from your feeder, and watch what happens to the squirrels.  In my experience, the squirrels will always return.

It’s unlikely that you’ll get much interest from squirrels if you only use corn.

How can I feed squirrels and make  more come to my home?
user
I don’t know exactly how you would do that, but there’s an easy way to try. You could build or buy a squirrel feeder and use it for this purpose.

What foods can you put in a squirrel feeder?
user
In my experience, the best way to attract squirrels to your feeder is to put a lot of fat nuts and shelled seeds.  I think nuts such as sunflower seeds, cashews, walnuts, and peanuts are the best.
