Responding to past comments

Ahopeful-I haven't tried the permethrin blitz but I do know someone who beat the mites with Zodiac, which someone else in the comments had used. I think my cat has used flea collars with the other ingredient from Zodiac. The flea collars seem to help him a lot. It seems the mites adapt to pesticides quickly, so the best way would be to kill all of them at once as you did. If you still have pigeons nesting on the roof above, this needs to be taken care of to finish them off for good.

I've been considering buying a pesticide powder to see if it might help further. So far, the best thing has been a salt and borax powder mix that I have used on the carpets. This has worked so well that we have stopped vacuuming the carpet regularly and we have not used the ozone generator.

Someone in the comments was talking about treating the car. The best solution I have found is to have the car professionally vacuumed. Steam cleaning was $100 per cleaning, but a professional vacuuming was about $10 a time, so it is chemical free and it can be done often. If you vacuum it yourself you might pay $1, which is cheap. I put the seats in large plastic bags (so I sit on a big bagged seat) and lots of borax on the floors.

Recently a friend of mine who has struggled with mites for some time found that he probably had a squirrel living in his attic and mice living in his walls. Any treatment for these is likely not to work so long as you have some small animals or birds living in your building.

Never use a flea collar meant for a dog on a cat. Some dog collars contain Amitraz. While Amitraz is the most effective pesticide for chicken mites (and likely for other types), never use it for a cat.

Another friend who is struggling with them has found that Ortho Home Defense really helps. He sprays his house and car with it often, but the constant use of strong chemicals may not be very healthy.

I'm very glad to read about people getting rid of this! It gives me hope and makes me glad.
