First I'd like to thank Kathy Guest for her info on the life cycle of the

The borer will eat everything that is connected and may even travel a short=

distance to a neighbouring rhizome, although this does not happen often. =
Your irises would have to be planted too close together for this to happen.=

Also, I live in an oak, maple, etc
forest. Keeping leaves away in the fall is not an option. If I remove iris
debris will that help. I had seen somewhere that spreading garden netting
over a flowwer garden in the fall will allow you to just lift off netting in
the spring along with the leaves and they won't get in among the plants. I
may try this after a fall clean up of iris debris.
Removing debris is the key preventative.
