Thanks all for the kind welcome! I was able to ask my question in another thread, but here is what I wanted to know:

Can permethrin loose it’s effectiveness?

A couple months ago I had a run in with a HUGE mite infestation. It took one of my EEs. I completely cleaned coop, run, yard, nesting boxes and the like from top to bottom. I then sprayed it all with permethrin solution mixed as directed on the bottle.

Then I dipped the hens in the solution and it worked like magic. No mites. I re-treated 14 days later (as instructed on the bottle). And again, magic! No more mites. I could not treat again because temps got too low to dip the birds. But, it seemed to work and we were more free for a month.

The my husband started filling the bird feeders in the back with seed again. Then the mites came back.

I cleaned all over again. Completely. Dusted once everything was dry from permethrin spray. Next morning I dipped the chicken. That night, most of the mites were still alive.

It shouldn't lose any effectiveness over a short period of time. It's more likely that the mites have found hidden parts of the coop to hold up and avoid your spraying. I guess you could try and again, but be as thorough as possible and maybe increase the concentration

Maybe I should have mentioned that i made a kind of trestle structure of metal tubing upon which I placed wooden roosts. Whilst I never had an issue with mites, I figured that it may be a deterrent

Yes, resistance can happen but not usually that fast.

Alternating between spinosad(elektor) and Permethrin is best. You can use some other. Also, use a liquid to spray the cracks and corners in the coup.

It is possible that wild birds brought in a different colony of mites that are resistant
