Totally true story. lolololol
Tried the Vanilla trees and they work great. The whole backyard smells like I'm baking cookies and no flies. But, the scent wore off after about 10-14 days. Might try to re-spray them but my DH just found a pack of 24 trees online for only $5.00 so he got those pronto. Even with shipping it was a ton cheaper than buying at the auto-parts store.
Now to find something for the mosquitos and something that works on the whole yard rather than just the vicinity of a few vanilla trees.
