Remember that these home made and commercial made deer/rabbit sprays MUST be reapplied every 4-6 weeks under dry conditions let alone after sprinkler or rain water so the type of sticker used is mute. I use dish soap when I remember and haven't had a problem of keeping those varmints away.

A great alternative to making your own deer spray is Terracycle's Deer Repellent. It's all natural and packaged in used soda bottles. It is member tested and recommended by the National Home Gardening Club! This is the closest I have found to homemade.
