How do you use Revolution on a hedgehog?

I didnt know you could.. but i looked it up for you.

If a mite infestation is found, discuss ivermectin versus Revolution with your vet. Revolution's dosage is 1 drop behind 1 ear for hedgehogs weighing less than 350 grams; 1 drop behind each ear for hedgehogs above 350 grams. Do not administer Revolution without guidance from your vet.

I got it from this site http://www.hedgies.com/hedgehog_health_care.htm

all the way down under symptoms, its under symptoms of quill loss from mites

Same way you do on any other animal. Place the drop on the back of the neck of the animal where it won't be able to easily get at it to lick it off. It's generally the smallest dose they make, but you should have your vet check the weight of your hedgie while you're there for the visit for mites and getting the revolution
