Same here in my house truck. Tried vinegar both types but they came back. Tried rubbing alcohol. They came back faster. Tried tea tree. They returned after a while. Then I gave up for a long time cuz it was too depressing. Did some gardening work for a friend, brought back a bunch of live willow branches and planted them on my "porch", also put down a bunch of cedar chips around them. All the mites disappeared entirely for months while the Willow was green with leaves. Leaves browned. Mites came back. But now the leaves are sprouting again and I'm considering covering my entire floor with cedar in some form. It's what natives used for thousands of years & there's no down side to cedar & willow.
