Will this kill yellow jackets?

It will, BUT!!! it works slowly, kills them in 2-24hrs, so if you spray/dust a wasp or wasp nest it's going to be MAD and very much alive while it chases and stings you. If you need to kill a wasp in person use one of the wasp sprays, those work to knock the wasp paralyzed in less than 5 seconds. If you want to prevent wasps from returning and nesting in the area, mix four tablespoons of diatomaceous earth in a quart of water , shake well, and use in a sprayer to coat the eaves/ceiling, and once it dries and they come in contact with it to try to settle there, they will get dusted & later die.

Will this kill Sarcoptes mites

I believe it will kill them as well as its already been reducing the population of any bug that have been crawling on my floor. The best way to use the product is to spread it in the area where you see the infestation using the most. I hope that helps

Can this be used in a crawl space?

Yes and works very well. Please just wear a good mask, gloves, and eye protection when doing it. Also take a shower when you are done.
