...Urine from mammal predators, meat protein, egg solids and garlic all possess sulfur-containing compounds that trigger prey-response behaviors. Putrescent egg solids and garlic, both ingredients in Liquid Fence Deer & Rabbit Repellents, are highly effective in deterring these animals before they even browse treated vegetation.
Review: "This product really does work for me. My only complaints: it smells GOD AWFUL. I suppose it is supposed to smell like predator urine - and I imagine it does. If it gets on you - just know you will need to shower to get it off."
This is the professional level product!

"A non-lethal, completely non-toxic liquid spray, the Skunk is the most innovative and effective riot control method available. And there simply are no countermeasures.
This harmless deterrent consists of an extremely foul-smelling liquid, with the viscosity of water, that can be sprayed over a large area using a standard water cannon. The overpowering odor of the Skunk drives rioters away - and keeps them away - effectively shutting down any escalating situation. Currently in regular use by law enforcement agencies, the Skunk has been field tested and proven to disperse even the most determined of violent protests."
