Get the smallest bottle. Use 5 parts water and 1 par Iver-On. Load it into a common spray-bottle....or into a syringe. About .01 ml into the syringe (the spray bottle delivers about this amount) and either spray or drop it directly onto your mouse in between their shoulders. Do not get it into eyes or open wounds. Treat once every 7 days for three weeks, then take a break for two weeks. After two weeks, treat again every 7 days for another three weeks.
I also lightly spray bedding and toys during treatment.
Iver-On has an extremely long shelf life, and is even safe enough to use on pinkies. I treat every new mouse with it, as it ois also a great preventative. If you are not sure how to mix it, ask a vet to do it for you.
I dilute Iver-on with 4-5 parts water. It's somewhat inexact, but it works. I just use regular tap water and have never had a problem of any sort. The key is to be consistent and do it at least weekly for three weeks, so that you get the mites in their various stages of their life cycle: egg, nymph, adult. If you want to do it twice weekly, that's good too.
I agree with Jack...I use tap water and dilute it to 5 parts water. No issues at all. I also agree that the key to making this work is sticking to the routine. Don't skip or wait too long, do exactly as the instructions say and you will be mite free in no time.
Well, I got the stuff, and I've started treating at the tate of two or three tanks each night, marking the date on the tank so I know which ones needs to be done again at the 2nd and 3rd week. that way it won't get to be a huge job on any given evenings' mouseworkings. So far the meeces seem to be tolerating the treatment well enough.
I have a question I'd like to have fielded by anyone who has experience using Revolution (selamectin) for Puppies and Kittens on meeces. Is it possible to dilute that and use it on mousies? I have used it in the past, and it's very difficult to control the dosage of the tiny bit of it in that teensie tube. I use a very fine syringe sans needle on the adults, and the tip of a bamboo skewer on babies. The Iver-On is a lot easier, but I wouldn't want to waste the last tube of Revolution I have bucketing around in the mousery.
