Ivermectin Pour-on: How long for results?

[Coldweatherbirds]

I got 2 barred rocks from a friend and they are covered with mites (lice?). I dosed them with 7 drops each of pour-on Ivermectin yesterday morning, but this morning the mites are still crawling around. How long should this take before I assume that I didn't get enough on the skin or the medicine is bad?

it should kick in right away, also, bathe them in adams flea and tick shampoo, and you will need to clean out the coop- here is a bit of info on the whole treatment

If you have a continuing Mite problem the real issue is you may be failing to treat completely all areas they come in contact with, The best practice I have found is prevention I treat all my pen's and run's twice a yr never miss. after putting the birds in cages, Totally clear out all old hay, litter and anything else, using a hose i wash the fire out of the coop's & pen's with bleach and soap, drain well then using a garden tank sprayer I treat the entire area concentrating on cracks and under sides of roost with Permitherin 10 diluted to 10-1. When dry i sprinkle Ton's of DE in nest boxes, floors, and feed & equipment areas, add more fresh hay more DE. I also sprinkle the DE around once a month need it or not to include a little scoop right on their back's. Never ever had Mite one ever and never will.​

Thanks. I'm looking for DE but haven't found any locally yet. These are new chickens. I put them in my quarantine coop (old doghouse) away from my layers and chicks. I'm going to pick up some dust for the quarantine coop today. When should I expect to see a decrease in the number of mites on my new birds? I thought the ivermectin would act quickly. Anyone have any idea? I really should know better than to take in unwanted birds, but I seem to do this over and over again.

I wouldn't mess with DE if ivermectin isn't doing it, I'd use pyrethrin/permethrin (that's what Adam's is) or Sevin 5% gaarden dust. You need to treat the living area anyway.

You problem may be the dose. Drops are not an accurate way of measuring because the amount in a drop varies from dropper to dropper. Dose of Eprinex (I'm guessing this is what you mean by pour-on ivermectin) is 0.25 ml for bantams, 0.5 ml for large fowl -- both for adults. A syringe without needle is the way to go, to me, should be able to get a 1 ml (cc) syringe from the feed store, drug store or vet.

so adams is the same? so you just saved me some money! what would the liquid equivalent be for me to use it as a dip? or is it necessary if you do the drops?

yes, i am always rescuing mistreated ones

Thank you Dawg, I did find that site too. My problem is that no one seems to be able to tell me how long it should take for the Ivermectin to work.

It's now been 36 hours, there does seem to be less mites, maybe, but they are still easy to find when I look around the vent.

I'm trying to decide if I need to re-dose, or buy a different brand of ivermectin. How long does ivermectin take to work?

I cant give you an answer on that. I have always used sevin dust. Ivermectin is used as a wormer first and foremost, anything else is secondary. Therefore you should not redose so soon with what you have nor with another ivomec product. You could cause internal damage or worse due to overdosing. At a minimum you'd have to wait 10 days before you redose...that would be the same time for any other treatment including sevin dust. Since ivermectin pour on is absorbed through the skin and into the bloodstream, I would think that mites should be dying off within a couple of hours. Severe infestations may take longer...how long, I dont know.

Ivermectin can take up to 2 or 3 days to completely kill the lice present on a chicken's body (in my experience).

However I'm not sure it works on mites!

Stupid question and one that is somewhere, with Ivermectin what is the withdrawal time on ingested paste or/and drops? I'm just trying to figure this all out again. Where I sell eggs to my neighbors I don't want to make anyone ill.
