I don't know if the moths can get through the mesh but they might get in under the roof or some other unprotected place. Juncos (small birds) sometimes get in; I suspect they walk between the bottom of the door and the gravel path. The protected situation also attracts many spiders, which may help control the moths. Most advice on controlling cutworms in the home garden involves making little cardboard collars and putting them around the young plants. That is probably fine for somebody who is growing a dozen little plants -- not a thousand. Jane McGary Portland, Oregon, USA
