I was looking around for a hamster mange cure after an experience with a vet wasn't much help. Mange is a tick, and there are two kinds of "dip" to cure it. The more common one is a pyrethroid insecticide based one, and most seem to use permethrin, which is basically Raid or lice shampoo. Less common, but probably more safe, and also "classic" is sulfurated lime.
You can get it as LimePlus or other products, but it seems like you can make it yourself, too. I haven't made this recipe, but it's based on this old recipe used by gardeners: http://chestofbooks.com/gardening-horticulture/fruit/Manual-of-Fruit-Diseases/Lime-Sulfur-Solution.html
To get sulfur, you get it from a garden store. It's called flour of sulfur or flowers of sulfur. Make sure it's pure sulfur powder (read the label).
To get slaked lime, or hydrolized lime, you can go to an Asian or Mexican grocery store, or a country store that has pickling supplies. In Mexican stores it's called "cal" and is sold in bags by the chiles and herbs.
The ratio of lime to sulfur is 1:2. So 2 spoons of sulfur to 1 spoon of lime. The twist is, the lime sold is slaked - or it's been combined with water, so it's really only 75% lime and 25% water. So make that 1 1/4 spoon of lime. Just add a little lime.
The recipe says to prepare the sulfur by mixing it into a smooth paste-fluid. Slake the lime in hot water - meaning mix it to allow the lime to soak up the water, but don't drown it. Pour in the sulfur during the slaking. This should result in a mess of smelly gunk. Then you add 5 times the water, and boil for one hour.
I suspect you can just take a cup of water and mix two tablespoons of sulfur in there. Then a cup of hot water and mix a heaping tablespoon of lime in there. Then, combine the two into ten cups of water, totalling a few cups shy of a full gallon. Boil outdoors on the bbq, because the stink will probably make you gag. You don't want to inhale it either.
Pour off the dark liquid into another container, leaving behind any precipitate (powder) at the bottom.
I figure go a little heavy on the lime, and light on the sulfur, because sulfur stinks. When the lime and sulfur are bonded, you want leftover lime, not leftover sulfur.
The liquid is a base. So this is dangerous stuff. Leave it in a glass jug, diluted.
Wikipedia says commerical concentrations are pH of 11, which is corrosive.
The dilution of LimePlus, which seems to be a concentrate, is 4oz per gallon of water. So you should aim to do the same with your concoction - take a cup of the dark liquid and dilute it into a gallon of water. Homemade is less alkaline than the commercial stuff.
