Linda, one of the biggest Lavender farms in the world is in Austrialia, the popcorn tree, not the proper name, over here can't be sold because it is invasive, the Loquat is a kind of Chinese plum tree. Jeanette a member here from Austrialia is the person that put up a list of some plants that may help with varro not sure if it will help. There was a post this week in the Down Under section about some using a chux towel folded up to help catch SHB's. Good luck
