Let me know what you decide to do. I have them for the first time this year, too. I was thinking they didn't seem to be bothering the girls that much, but realize they are all scratching areas of feathers off; poor Rosie looks like she's molting (she does molt really hard, but it seems a bit early?)

Frequent dusting with DE (and really aggressive coop cleaning) may be the only organic way, but I'd be curious if anyone has used essential oils on birds with any luck.

I have the chemical spray if you decide you want to go that route. It's permethrin-based like the "dusting powder", I'm pretty sure.

One of my hens has stopped laying completely and looks worse every day (it's been like this for a while but I thought it was stress-related - I just saw the mites). Antoher seems to have stopped in the last week or so. I've cleaned and disinfected the coop, and will likely do an aggressive DE application. I've read it helps with prevention, but not so sure about treatment. I would like to have something stronger on hand just in case, but thought it would mean a trip to the valley. I'm leaving town in a few days so will likely do DE then check it when I get back. I may be in touch with you in a couple weeks if I still see mites around - thanks so much!

No problem. Duncan suggested multiple coop cleanings ("clean, dust, repeat"). My problem is I can't get my coop out of the pen - certainly not without help - to actually hose it down. So I can only dry clean.

Might be time for a new coop for me that's easier to clean.

Anyway, I got the spray at my regular veterinarian after the bird vet (Night Owl) used it on my girls.

Ok thanks Alyssa. Funny, I called Night Owl but they said they couldn't sell anything to me unless they saw the hen first. I may go big up a big bag of DE today, if anyone needs any I would LOVE to share it...50lbs is a bit too much for me....

Night Owl doesn't have it anyway. I got it from my cat vet.

Hi Vicky,
Our recent battle with mites worked out well, and the key was constant vigilance for 2 weeks since they are so quick to reproduce. They started out sparse and then they were EVERYWHERE! We started by dusting all the birds (and the coop, especially roosts and the nest box) with DE, Dr. Bronners peppermint and lavendar soaps, and neem oil, but that can only do so much.

What seemed to work best was a manual cleaning in which I used the highest pressure setting on the hose and tried to get water in every crack. I took my coop to another area to do this, but even if that's not possible, at least they will be flooded away. I sprayed it, let it dry, then spray it again as more mites crawl out. I may have done this a third time. Be very very thorough. Once it dried again, I painted all surfaces with linseed oil (flax-based), letting it drip into the cracks. If you can caulk any small cracks, or wood joints, you'll remove their hiding places. The oil takes a while to cure, but after that, I dusted everywhere I could (make sure to dust around the base of the coop to keep the mites from crawling back up.

At this point you will be covered in mites.

The week after doing all that, I went away for two weeks and really didn't want to see them return, so I went to Army and Navy and picked up a can of "Knock Down" crawling insect killer. I removed the hens and very judiciously sprayed it in any cracks that mites may return to. Its active ingredient is permethrin (if you can find pyrethrum, that's the natural version and it's derived from chrysanthemum, though it's still poison).
Feel free to use some of my can. I think I used about 1/20th of it and hope to not need to use any more. Keep the hens out of the coop for the rest of the day. The Knock Down claims a 60-day effectiveness, which is both comforting and disturbing. I hated to resort to it, but I consider it integrated pest management. I haven't seen a mite for months.

In the end, I think the water hose (jet setting) and linseed oil were the best tools.

Duncan

Can you (or someone) help me get my coop out of my pen so I can try this this weekend? It would be very bad for me to flood my pen, even if the hose would reach.

I'd be willing to consider investing in another, easier to clean/move coop, too, if you have time.

I'm away over the weekend, but could help on an evening too.

Thanks. Supposed to start raining tomorrow. Is it important that it dry in between? (The hot, dry weather would have been perfect for this, alas...)

Maybe some ideas for a new coop. Nothing too fancy.

I still have a lot of DE if you want some Vicky. I'll be around today.

thanks Duncan I'll give you a call.

Alyssa, I've got to deal with mine and am leaving town on Friday, but if i get time i will certainly help. Could the 2 of us move it? Feel free to call or email me

We also just discovered a mite infestation last week, after I noticed one hen with a very pale comb...she was anemic from the mites sucking her blood! Poor Dolly. We've dusted the birds with DE, cleaned coop thoroughly, caulked all cracks, and have been using shop vac to suck up mites during the day. Duncan, you are right - you do get covered in mites after all this, gross!
It seems despite all this, mites are hanging in there. Hens are doing better, but its still a problem. Could we use some of your permethrin spray if anyone has some extra?
