You need to use an actual miticide, a pesticide designed to kill mites. If there were dead rats, chances are they were the result of some species of rat mites. Bifenthrin is usually the go-to miticide and can be applied either by hand or by fogger to the attic and sub-space areas. Don't fog bifenthrin inside a living space; however, spot applications using a hand pump sprayer are allowed. Evergreen or any pyrethrum-based product is extremely short-lived. Microencapsulated pyrethrum will last a little longer. I have never heard of doing a base treatment and then applying a pyrethrum product for mites. Usually, a miticide such as Bifenthrin (Talstar or Bifen) works by itself. The most important thing is to remove the dead rats, exclude all other rats for entering the premises, remediate the areas where they were living and breeding and prevent this from happening again. Using an IGR such as Gentrol can also help overcome the breeding and propogation process.
