How do I keep squirrels out of my container plants on my porch?

Hot sauce

I've done some research on repelling "rodents," and I use peppermint oil. You can douse a few cotton balls or mix with water and mist the plants.

Use peppermint plant or herb, rodents do not like peppermint, so if you have an area where rodents Like Mice get into use peppermint oil or a Plant that will drive them out also with clear your home of spiders.

I put dryer sheets around the plants - they kept eating the blooms off my squash plants - they don't like that and neither do mosquitos

Have-A-Heart squirrel traps.

Cover planter with chicken wire after planting and allow plants to grow through it!

Use Blood Meal, Squirrels hate the smell. You can buy this at any Nursery

I fill the gaps between plants with small rocks, about egg size or larger. As the plants grow, you won't be able to see the rocks. I've also used broken pieces of pottery. I've tried MANY deterrents and the rocks seem to be the most effective.
