Eprinex Dosage?

[purpletree23]

I found mites on one of my hens. Her fluffy tush feathers are gone and the skin is irritated. I could not find any signs of mites on her during the day but I knew that something was going on. Tonight I went out after dark and checked her over again (she is not a happy camper) and I did find a few mites.

Where there are a few mites there are probably millions.

I've researched the site to find as much information as possible and instead of a dip or Sevin dust I want to try Eprinex. I have Ivermectin but it seems that Eprinex is recommended for external pests and Ivermectin for internal.

Can anyone give me the dosage per bird please. When do I repeat the application?

I'm pretty sure the mites haven't taken over the coop because every time I clean it out I sprinkle Sevin on the floor and all cracks, roosts and nesting boxes. I'll know tomorrow when I do an unscheduled coop clean out.


Any input would be appreciated.

If you have the liquid (most preps are 5mg/mL - 1mL=1cc). See thread below for other preps as well (worming thread with ectoparasite control thrown in for good measure).

One thing we've found is that we've had better luck with slightly higher doses than recommended in thread (pour-on .25cc small/.5cc 6-8lb.) use on upper back between wings, on skin.

Very complete ref. on ivermectin: http://www.inchem.org/documents/pims/pharm/ivermect.htm

When cleaning out neighbor's coop (badly infested with mites) we sprayed down all cracks/crevices and roosts with a solution of Eprinex and tea tree oil (tea tree oil kills mites as fast as Eprinex but can be toxic if used directly on chooks) and their flock was placed in temp. run for 24hr. also treated chooks with the eprinex pour-on. Following treatment none of their turkeys, that would wander over here through the woods to visit with ours, were infested (I checked - had treated them with 1cc per turk).

Thank you for answering but I'm afraid I don't understand. Am I correct in saying (read all threads) that for external pests like mites i can use Ivermectin? I have larger birds (buff orpingtons and speckled sussix) and from what I read the dosage is 5 drops on the back of the neck on the skin and not the feathers.

I'm assuming I would re-treat in 10 days?

I'm not sure about the Eprinex Dosage, but to ensure that the mites are gone from your coop, I would recommend picking up a small bag of DE (Dichotomous Earth - food grade) to spread around in the coop in bedding (and/or the chickens food). This will kill off any other mites.

If it is the oil based 5mg/mL (we use a brand called Agrimectin). Yes, Ivermectin/Ivomex/etc. knocks off external parasites. We loaded up 1cc syringes and went to work (.25cc ~ `5 drops' - best to be a bit over as making sure you get it all on skin can be hit and miss). With a lot of birds it is best to wear nonpermeable gloves, unless you need wormed, as the oil based solution will will migrate transdermally (not a lot through skin, but some). Yes, repeat x10 day for heavy infestations.

Good luck (If I confused things further please post up manufacturer name of product you're using)!

Adams Tick and flea spray is also a good adjunct.​

Eprinex dosage is 1/2cc for standard size and 1/4cc for smaller chickens.
You can use the ivermectin pour on (blue in color that smells like alcohol) to treat them. The dosages are provided in Ivan3's BYC link.
Whichever one you decide to use, the liquid needs to be placed on the bare skin (normally on the back of the neck.) The ivermectin pour on is quickly absorbed into the bloodstream when put on the bare skin. Eprinex is clear (in color) and a little thicker in consistancy. When I use eprinex, I put it on several places on the back of the neck to absorb quicker due to it's slight thickness. Redose in 10 days as Ivan3 stated.
You will still have to treat the interior of their house as well, and repeat in 10 days. I recommend sevin dust.
ETA: There is a 14 day withdrawal if you use the ivermectin pour on, no withdrawal using eprinex.

Was researching bout mites....I have both the Ivermectin injectable 1% solution(that I put on back of the necks) and the Epirnex....which is better?

Quote: The ivermectin injectable is just that...an injectable, not used as a pour on. That's what ivermectin pour on is for (put on the back of the neck.)
The injectable is useless as a wormer, but will still kill mites:

Ivermectin pour on and eprinex have both lost their effectiveness as wormers due to worm resistance in poultry...overused as a miteacide instead of its primary purpose as a wormer.
You'd be better off using valbazen or safeguard products to worm your birds.

I use valbazen for worming.

Which do u recommend for mites between the 2?

 

[dawg53]

I use Sevin dust.
