Narcissus fly

??? I recall reading somewhere?that the narcissus fly can rarely attack lilies, Dutch iris and a few others but as Jane writes they prefer the Amaryllidaceae.

?? One organic method of control is planting the bulbs in the shade where the flies are far less likely to lay their eggs.? I have some diatomaceous earth that I am planning to try next year as a deterrent for bulbs that require full son.? Removing the dying foliage and filling up the holes where the scape and foliage was is supposed to help also.
