Red mites HELP please!

Has anyone sucessfuly eradraticated red mites from a coop? I'm using neem oil with a little washing up liqiud a few drops of eycalptus and peppermint oil in water to spray on the coop, steamed with a wallpaper steamer and using DE on the floor and in cracks. My girls are still being bitten every night
Im even thinking of getting a platic coop as eaiser to clean and less places for red mites to hide.I really really really dont want to do that

Hi,
once you have a huge population, it is really difficult to knock it down.
There are a few things: a product you put in the drinking water, it stops the mites immediately. Never tried, and I am unsure what product it is.

One thing to avoid them being bitten at night is to put the roost on oil containers, similar to what is shown here. You don't need to buy something fancy like this, a small can, threaded rods, nuts and rubber also work.

Diatomeous earth works, but it needs a lot of it. And I heard that depending on where you buy it, it is not fine enough to kill the mites.

Old timers used soaked tobacco leaves to spray the coop, the nicotine killed the mites. Birds still put cigarette buds in their nests, and therefore reduce parasite load.

Thanks Hans. The nicotine thing is interesting. I wonder if the new fangled vape liquid would work

I am sorry to hear this and I have never had this problem though I wonder if dusting the chickens with the DE might help>

From what I have researched, it depends how bad of shape your girls are in.

A good first step is to clean the coop as you have done. I'm assuming they have access to a nice dust bath area? Mix some cooled wood ash or DE in their dust bath to help.

The next step I would recommend is now make it difficult for the mites to stay on your chickens. I'd grab some cheap cooking oil (Canola/Vegetable) and slather up your chickens legs. They are going to get dirty, but that is FINE. Your best bet is to do this at night while they are roosting. The oil will help prevent the mites from crawling/eating and help starve them out. The girls will go into their dust baths and get dirty but that is part of the process.

Thank you for the replies. My chickens are free to roam around the garden in they day so i will put some DE in their dust bath spots. No wood ash available.

I usually dust the house liberally with DE and that seems to do the trick.  I clear out the house first and give it a bit of a sweep, then dust the floors, walls (as much as possible), nest boxes, roosts, etc.  I think the mites are like bed bugs in that they don't really live on the chickens, but rather in their house.  One application of DE a year works for me.

I use a combination of all the recommendations that have already been made - thoroughly clean inside the coop, removing all the perches and bedding, spray the cleaned coop with a product for killing spiders and dust the girls with flea powder.

If after spraying the coop, there are any dead mites, I treat the girls individually according to weight with Exzolt on a piece of bread (we only have 11 girls so can lock them inside their cage and let them out individually after I've dosed and dusted each one).

As a preventative measure, once the weather warms up, I purchase predator mites and spread them around the soils inside their cage and in their run https://www.bioforce.co.nz/products/Poultry-Defender.html  

For scaly leg mites, I apply a scabies cream to their legs that is for human use and re apply after 2 weeks. In between times, I apply comfrey salve very liberally to smother the leg mites.

Thanks all
