Three Habenaro peppers puree'd and strained, mixed with 1 cup of vinigar, added to one gallon of water, will solve all of your pest problems from the borg, to Horses and everything in between (Except People of course). It is totally organic, and will last for a long time. Animals will remember the experance and leave your garden alone, but bugs don't so you will have to spray every 60 to 90 days. Rain will wash the mixture away so you will have to spray again after it rains and the plants are dry. The best part about this spray is that it dosen't cost much to make, and even less if you grow your own Habenaros.
