I have been constantly having trouble with red mites, there is no chemical or anything else that I didn't use to get rid of them, but no success.
Extreme circumstances call for extreme measures.. sulfur is effective at killing lots of things.
After some time, THEY CAME BACK AND OVER AND OVER AGAIN.
This is often the case.. since wildlife are not being treated and sometimes eggs are not treated so follow up is required. Also weather changes either in favor of or against.. No matter what you use seasonal or yearly follow up may be advisable..
Any permethrin or pyrethrin based product should be effective.. sometimes sold as horse fly spy in the states. They are also safe for use on layers and all ages of chicks with NO egg withdrawal time needed.
Carbaryl is effective, usually.. maybe not labeled for use in chickens though. Of course fire kills lots of things as well.
There are many species of mite that are red, clover mites for example male me panic every time I see them.. and red mites do not live on chickens but only come out to feed on them.. colonies often found under the roost. Are you seeing them on the birds to and are you able to post photos?
Consider using maybe a neem and/other essential type oil spritz or something like that MIGHT be helpful..
Sounds like nothing will truly eradicate them and therefor I suggest changing the expected outcome and managing what it IS, unfortunately. Which is to say requires ongoing management possibly including a multi pronged approach could include back to back treatments within a specified period for ALL 60 birds.. plus adding stuff to their bath, cleaning or changing the bedding type, etc.. or EVEN alternating treatment product/method.
It's a worthy fight and I value the cause!
If you have any way.. like human B complex added into feed/water.. to help boost their personal immune system, on OCCASION only.. then there isn't much to lose. An actual poultry or avian vitamin, mineral, amino acid supplement (not electrolytes) would be an even better choice if one is available. Sometimes found in the pet section of regular stores. Feed stores often have a few choices. I mention this because ALL thing immune system related are also effected by nutrition which can ultimately either help fight off internal/external parasites. Have you ever done anything to rid the chickens of internal parasite load? See, I'm talking one, two, three punches or all that you got at one go.. Yes, that MIGHT include treating the property as well as the birds, coops, roost. lay boxes.. etc
Not to be left of the list of vectors for these external parasite are the ever freeloading rodents.. rodent control in VITAL to external parasite control. Even though I collect feed, rats still come looking for shrapnel, and squirrels are bushy rats that most will never consider. Switching the traps up and baits help.. there are a few threads on effective rodent control.. but it's always an ongoing battle that will not cease as long as there are livestock. Sounds like that may be the case with these mites.
I feel silly for asking but since I'm unaware of your actual poultry understanding despite length of stated experience.. but are you sure you're dealing with mites and not standard molting?
Some years I have to treat my birds for poultry lice and other years not.. The weather changes and conditions with it.
The most common practice is MONTHLY after dark check using a flash light.. With a flock that big (miner used to be 72 strong).. I pick a few of the scraggliest looking ones.. maybe 10-20% look for angry red skin, creepies running away, or dried "dirt" looking egg clumps near feather shaft bases below vent near abdomen. Try to select maybe new random chicken each inspection time. Treat EVERY one ONLY if any signs are found. Studies show that 10% of birds are carrying the majority of the parasites in any given flock.. they are technically the weakest link.. but of course when we start talking about high density populations.. favorable condition can allow things to grow out of control rapidly.
Lots of good suggestions made while I was tapping at this keyboard. Hang in there, I know how exhausting it can be at times!
