I have a Dr. Huey growing right now but I don't have a huge problem with midge so I'm not sure I want to attract them to lay eggs in it.

Unlike JBs, rose midge are poor fliers--they typically arrive via infected potted plants.

Selective watering may also be useful. Holding back water may induce dormacy, stopping fresh new growth, insuring that midge will only attack the target plants that have been well watered during the hot summer months.

This may be quite useful as an organic control for those who don't want to use insecticides in their yard.
