Repel Garden Rabbits

I have families of rabbits living under my Thuja, with the consequence that it's open season on the gardens until they mature a bit (I plant flowers, not vegetables, but the damage is still very bad).

Over time, I've looked up and cooked up a homemade repellant that works fairly well. Here it is:

In a one quart sprayer (or multiply by four for a 1 gallon sprayer, and so on):

1 tsp Tabasco sauce
1/2 tsp dish soap
1/4 tsp white Elmer's glue (optional but very helpful) (distasteful to rabbits, and helps the solution stick)
1 tsp Neem oil (optional but extremely helpful) (helps the solution stick and mildly distasteful to rabbits)

Spray plants lightly; no need to soak the leaves. 1.5 quarts covers 2,000 square feet of flower garden around here. Reapply after moderate or heavier rainfall, this should stick through light showers.
