What are these?  Can you give some examples please?

I gave this example of promising a treatment for varroa. Of course, I
realize that all fumigants contain chemicals, everything does. But I
was referring to plants or plant extracts. Some of these have shown
results under certain conditions.

A plant that you could burn in your smoker that killed mites, now
there is something that we all could use! Unfortunately, I don't know
what it is yet. I just think the idea  holds promise.
