I sympathize with the animal problems
This may be redundant--I've written about my solution to foraging animals repeatedly, but I don't mind presenting it again. My solution to warm-blooded pests is a cheap solution of rotten egg, which I had noticed seems to be an important ingredient in all the expensive repellant mixtures.
Here's the recipe: mix 2 raw, scrambled eggs with 2-3 quarts of non-chlorinated water in a 1 gallon jug. Let this stand at room temp for about 7 days, shaking it at least daily to prevent settling.
Every day or two, or right after it rains, sprinkle small quantities around the plants that you want to protect. I often use an old paint brush to spatter it on the ground, but you can also dip the ends of thin strips of paper towel in it, and hang the strips on branches or pots that need protection. Just renew the strips every couple of days, bc they lose their potency. Human noses aren't as sensitive to this as you may think. Animals hate it.
A friend of mine was bemoaning the fact that deer were destroying his raspberries--he lives in a forested area, and actually had never even gotten fruit off of his plants. He used this mixture, and it solved the problem.
The mixture stays 'bad' for 4-6 weeks.
I hope this works for you!!
A note on deer: I'm in suburbia, so deer are not a problem, but I've read that you can keep them away by stringing extra fine monofilament fishing line around the area to be protected, about a foot off the ground, and several feet from the protected plants. Deer get freaked out by anything that might bind their hooves, especially if they can't see it. You could also put it around the perimeter of areas to be protected. My spool of extra-fine cost a couple of dollars, and has almost a mile of line on it.
This is almost the same as cow grates used by farmers to keep cows from leaving a pasture through an open gate--it's an iron frame with parallel 1" wide openings on it. Cows won't cross it for fear of catching their hooves in it.
I hope this helps!
