Ivermectin?

Hey guys, as some of yo might know from an earlier thread my rats have lice. Well I finally manage to get some Ivermectin. I just had a couple questions to ask the people with experience here.

How much should I give? And is this good stuff to use?

I have two pregnant mothers, will this affect the babies being feeders?

Also have a few small one that I am letting grow up, if I treat them can I still feed them off?

This is the stuff I got for them it is paste in a syringe.

Also I have been using aspen bedding but it is getting pricey. I found this bag at the feed store for 16.00 and its huge compared to what I usually buy, but they could not inform me of what kind of wood it is. I am almost certain it is pine from the smell. I know pine is toxic, but this is Kiln dried, I thought I read somewhere it is ok to use if it is kiln dried?

Any help would be appreciated!!!

That paste is fine. Its a rice grain dose for each rat once a week for 3 weeks. I wouldn't treat the ones you intend on feeding off. Just QT them. And the nursing babies will be treated by nursing from treated moms.

Kiln dried pine is fine.

So I should not treat the ones I am going to feed? But I can treat a pregnant mother? So wil I be able to feed off the babies?

No, the mom will pass the treatment to the baby. A few months should be long enough for the drug to clear.

like in that case I am better off waiting until she has babies! I guess they will have to suffer it out for another couple weeks. Not really how I wanted to do it, but keep need fuzzys

The size of that bag is not really worth it, I can get 9cufeet for 6$

Of kiln dried pine? It is worth it to me. Either get aspen. 2 cubic feet for 25.00, or I can gt regular pine huge bags for 9 bucks. But my breeders are also pets so I would rather spend the extra money to keep them healthy.

Pine is not toxic... It's cedar that causes issues. Besides, you'd be hard pressed to find any pine bedding that isn't kiln dried as long as it isn't an outdoor mulch mixture.

OK Question. So he is treating the rats themselves with Ivermectin. What about the bedding? Won't you have to treat the bedding to avoid a re infestation? Did I hear about someone using the lice spray from the drugstore?

I've used PAM in the past for rat bedding. But lice spray should work too.

Or you could use cedar bedding and for go the PAM as the toxic part of cedar and Pam are the same root, phenol.

Pine causes respiratory issues in rats, I did a lot of research. Also ALL pine I can buy in pet stores is air dried, says right on the bag.

I treated the rats every Sunday for three weeks, I froze all bedding, Changed bedding twice a week with bleach cleaning every time, so far so good. When I would put a rat in the freezer they yo could see the lice leave the body, that is the only way I knew they were there. Now I don't see anything and my rats seem to be much calmer. Also no dust on the fur (eggs) so i think for the most part I have gotten rid of the lice.

Plain pine is toxic. Kiln dried pine is safe.

yes I know, I am using kiln dried. I was replying to someone saying it would be hard to get pine that is not kiln dried. All the pine in pet shops are air dried.

Air dried is NOT kiln dried. Kiln dried is baked effectivly air drying is just aged naturally and the phenols are not cooked off.

I'd be careful about using Ivermectin like that without some way to measure it more precisely...the "theraputic range" (the difference between effective and toxic) for ivermectin is rather thin. That is, it doesn't take much more from the real dose to cause ivermectin poisoning. Also, horse strength worming paste is sometimes 100x more concentrated than even the canine strength. This means that even a small discrepancy in the amount given can administer a radically different amount of the active ingredient (in this case Ivermectin)

I use injectible ivermectin for my mice; a simple subcutaneous injection under the skin at the back of the neck. I pick up insulin syringes for 6-8 bucks a pack, and just use that. This allows me to more readily control the concentration.


Don't mean to sound like an encyclopedia...I just spent the past 16 weeks having this drilled into me in Pharmacology class for my Vet Tech program lol

Horse paste is only around 2% ivermectin. Hardly concentrated. Plus the dose ratio to give to a horse is substantially larger than the amount given to a rat.
I have a specific dose if anyone is really that interested, but eyeballing a rice grain size is fine and safe to give rats. I'm not saying your method is wrong either. Its not because I do the same time to time. But the horse paste isn't wrong either if done correctly

This is coming from someone who works in a medical research laboratory with lab rodents daily.
