he, this is my 3rd post in as many days

I just wanted to share an idea with you. This morning I got the idea of using essential oil to keep bugs and other critters away from my roses. I did a bit of research and found out that Patchouli and Cedarwood oil works good. So I took a bit of paperboard and wet it with Cedarwood oil. Put a cord through it and hung it in my roses. Careful of course. The smell of it should keep bugs away. At least I hope it does. Of course I don't know if it will also work on good insects. Guess so.
Other carrier material can be pieces of wood (maybe the most esthetic solution), cloth or maybe even leather. The important feature should be the ability to hold the oil.
Rain could be problematic as in washing the oil away. That's why a very absorbing material should work best.
Anyway, I'll keep you up to date about it. And I also want to try Patchouli oil. Maybe ground insence sticks in a cloth pouch work, too? *runs of*
