Do you repeat ivermect pouron after 7 days on chickens

[WhiteWyan]

Hey guys

Started seeing mites crawling on the eggs. Long story short I treated every chicken with 5-6 drops ivermectin pour-on (5% for cattle) 7 days ago.

Now from what I've read about treating these little monsters (northern fowl mite is probably what I'm dealing with) you need to re-treat after 7-10 days.

I've never come across an article about ivermectin, however, that indicates that a repeat dose is necessary.

I'm willing to get in touch with a vet but I just thought I would ask here first.

Do I need to repeat the ivermectin?

Thanks!!

I didn't use ivermectin when my chickens had mites. I used Poultry dust on the chickens and Permethrin spray in the coop.

You'll need to do a full coop clean out and burn or dispose of the bedding away from the coop where the birds won't be able to get to it and get re-infested. Here's a link to my thread from when I had to deal with mites (it might mention ivermectin.. I'm not sure what all the suggestions were). The people who responded had lots of very helpful information.

I have cleaned the coop twice and tried sevin dust in the coop and on the chickens as well. Kept seeing mites on eggs, also they were in their feathers.

I also bathed my worst chicken in the tub with Dawn. I sprayed the coop with poultry protector spray by manna pro, too. I'll check the thread and see if anyone repeated ivermectin after a week. Thank you for the link.

Hi.

I'm curious what made you go STRAIGHT for ivermectin when it isn't even labeled for use in chickens. ONLY way I would EVER use it would be for depluming mites which are microscopic and live inside the feather shaft therefor cannot be treated with topical solutions.

More than worrying about retreating I would be sure you are with holding eggs. I would retreat according to the directions for the targeted pest. Where did you get your original dosing information from? Any egg withdrawal period? Have you come across article suggesting you use it for poultry?

NFM are VERY common in the environment and EASILY treated with things that are labeled as SAFE to use in chickens. My preference is the permethtyn spray that was mentioned. It cheaper, safer and effective with NO required holding for eggs when used according to directions plus extremely easy to use. It comes in concentrate forms or I bought mine labeled as horse fly spray in a trigger bottle to keep the mosquitoes off my goats and dogs. It is labeled for for many species as uses. It costed around $10 and treated 3 large dogs, 2 large goats, and 60+ birds for more than 2 years!

I spray my roosts, walls, lay boxes, and coop floor... as needed (or when I treat the birds and have never done a FULL clean out). My vet said when we keep poultry year round there is no such things as seasonal pest. But I do realize some places the weather really is a contributing factor and some seasons definitely increase certain challenges. But controlling carriers like rodents and other visiting birds to you property might be an important factor.

And mites can build resistance to drugs, so that could be a factor for you as well... if others in your area are OVER using them.

I saw what I would call less than stellar reviews for the poultry protector. If you aren't getting the results you want I would try the permethrin. It has been VERY effective for me for lice and mites.

I never cared for the sevin dust. Just because I don't like dust in general. I have read part of the issue with using the dust is getting it all the way to the skin can be difficult. For me I just don't like breathing what they shake out.

The permethrin spray (comes in powder but we aren't freezing and I prefer spray) also DOES have a residual effect that keeps working for a period of time but that varies according to species and so does suggest reapplication accordingly. Never had to so far. I only treat upon confirmation or suspicion of parasites. I don't believe in prevention, at least not with chemicals that pest build resistance to. So I am careful not to use it for NO reason.

Good luck getting rid of them buggers!

I have been throwing away all eggs. Also I've found pour on ivermectin in multiple threads here. Darn I have to get ready for work! But thank you for the reply eggsited I will read it later tonight!!

Hey so I read your post and I agree, the sevin dust is gross. I decided to use something else. I read a few posts on here about how resistant the mites are to permethrin (even saw a picture of a can of permethrin powder with mites crawling all over it).

So while I had been considering permethrin, I saw so many posts about them being resistant I looked for something else. Ivermectin was mentioned as being great for treating a wide range (worms lice mites etc) even scaly leg mites. I found dosage on multiple posts, pretty much seemed to be a consensus of 5-7 drops of the 5% pour on per bird. Egg withdrawal is suggested as 1-2 weeks

Where are you located ? I am in upstate New York. I have found no mites since I did the ivermectin.

I guess I won't repeat to ivermectin. If they come back I'll use permethrin!

I'm in California.

My research did show that mites can indeed build resistance to the permethrin as well as many other drugs. Which is one reason I don't just treat on a schedule but as needed. So far I'm not seeing any resistance here. It could be a wise choice to switch up (rotate) what you use especially if you are seeing resistance.

When I saw ivermectin research in cattle they detected residual for more like 30 -60 days (it's been a while and detail fades). I know chickens will metabolize things differently. I'm a little on the cautious side and so would personally withhold eggs for at least as long as listed on most other poultry worming medicines... UNLESS there is scientific studies showing residual effects. I have NO doubt that Ivermectin is good at killing things! Just think it's too harsh on the system. But sometimes you do have to do what you have to.

Glad them buggers aren't crawlin everywhere anymore!

I recently read an egg withdrawal chart for all the various chemicals - it recommended 21 days for ivermectin.

I'm about to try the pour on drops for the first time as my chickens have some kind of parasite that the poultry dewormer didn't take care of and they seem to have lice too... I took in a few discarded chickens and learned the very hard way not to introduce other birds to my flock. There is a very rampant wild chicken population where I live and it's really hard to keep my flock healthy.

@EggSighted4Life the OP is right, there is a ton of different treatments suggested for mites on byc and add to that tons of opinions about poultry becoming resistant to any given treatment.
It’s very hard to determine via just going through many posts what the best protocol is.
Just please realize that a lot of people are going through the sites info and trying to do the best they can do with the info provided.
