Good Squirrel and rabbit repellent?

For the garden, if you mean veggies, the only effective way to keep the rabbits out is a fence. Squirrels don't like veggies very much, but they love bulbs and no fence can keep them out.

Some garden centers in my area say they have a stinky repellent you put around the plants and the rabbits stay away, but I haven't tried it, you might as they say it works.

The animal repellants work good for the deer, sometimes rabbits. Try using that and plant some Marigolds, rabbits hate the smell of them.

I put a small radio in a ziplock bag and turn it on at night. It keeps the creatures away. Put it in the garden.
