If I had mine inside I would definitely use the sticky traps for sure. Mine are all outside so it would be a waste for me so I use the Bayer products that Mona mentioned above (that I told her about). A lot of hybridizers use the Bayer Tree and Shrub in their greenhouses, Bill Waldrop, Larry Grace to name a couple. There are several on the email Robin that talk about using it (can't remember who) and that's where I learned about it in the first place.
