What is the best equine tick repellent?

i need something that will keep my horses protected out in the pasture, waterproof, and they cant rub off when they roll.What is the best equine tick repellent?
Look for products with permethrin... it works GREAT... For humans, the clothing 'soak' process works REAL well - the below link from the boy scouts of america (I have checked the word doc, and it is safe...) has good directions on how to do it... - will treat clothes good for a couple months - works even after washing!!! and 99.9% tick prevention...





Harmless to humans and can be applied to horses, dogs and cats. One place to get it is agricultural and equarian (sp? - horse) supply stores. If you buy it at 13 or 10 or 2.5%, you just mix it according to the directions for use on human clothes (NOT SKIN) and for horses/pets... it is the best thing for tick prevention... Deet and other repellents don't come close for ticks...





And you can spray the yard/grass with the same product - just follow the directions...

ok so in Australia we have swift it's like a spray that goes on once every month along their dorsal muscle, clout you get it from the vet it's a pink paste and you put it along their dorsal muscle as well this does it for about a month. and for big tick infestation promoxin it's a liquid from the vet and you mix it with water and spray it all over the horse and that lasts about 6 weeks
I live in Puerto Rico, and we have ticks really bad here. I use RepellX. 1 part RepellX and 9 parts water. It is really strong and protects against ticks, flys and mosquitos. I dont have the bottle tonight, however I will check tomorrow. If you are interested. I use bronco as well...but it doesnt do near as good as RepellX
I really like Endure. It's waterproof, rub proof and it lasts a long time, 7-14 days. It's also a fly spray and protects against many other bugs, too.
