If animals think of your garden as the local salad bar, here are a couple of sprays to try. There's no guarantee they'll work, depending on how many critters there are and what their other options are, but they are inexpensive and worth a try.

If using the optional fresh leaves, put them in a blender with a cup or two of water and puree until smooth. Strain the puree through a coffee filter to remove any solids that could clog your spray bottle. Put the "tea" into a one-quart spray bottle, add the hot sauce and soap, and add water to fill the bottle. Spray on the surfaces of all your plants. Repeat once a week or after every rain. Store any leftover spray for up to two weeks in the refrigerator.
Milk is a surprisingly effective deer deterrent.
Put the milk and soap into a one-quart spray bottle and top off with water. Spray on all the young tender growth in your garden. Repeat once every 10 days during the growing season. This spray doesn't keep well, so pour out any that's left over and clean out the sprayer after each use.
