>Had a couple of questions about the wintergreen and the essential lemon grass oil. I'm assuming the wintergreen is for trachea mites???
No. It's to boost their immune system and help with the Varroa mites.
> And have you had good success with the lemon grass oil?
As swarm lure? Yes. To quickly set off robbing? Yes.
It should have roughly the same effect as the wintergreen.
> I tried it this summer, but without any success...
