Will lemon slices around the planted tomatoe pots keep away squirrels?

I've heard of this and tried it but it did not work for me.

I had some success with mothballs, but that's dangerous if you have dogs.

I resorted to netting.

We've tried everything, and the only thing we've had real success with is trapping and relocating the hungry little critters. We have found that marigolds seem to help repel ground squirrels. Good luck!

Human hair... go to your nearest salon an take the cuttings for a few days, spread it around and in your garden. This should keep all manner of little critters, including cats, out of your garden with the bonus of putting much needed nitrates back into the earth. Marigolds and netting work too!
