For several years I've had a "darkroom" in a curtained off space in a non-insulated garage. During the Summer, I usually print early in the morning to avoid excessive heat & humidity. As far as cockroaches, they seem to be less of a problem each year. Maybe its because of the alt process chemicals I have stored in the darkroom space (hopefully, cockroaches are not my canary in the coal mine). I do use some roach traps scattered around the garage, and have noticed Geckos on occasion.
