lobster dubia etc...i live in florida...dubia arent legal...im terrified of roaches and am allegeric to cockroaches. I can smell them even if they arent present,and there isnt an infestation. I know some roaches climb. that really freaks me out. Is it safe to use vaseline or cooking/olive oil to keep them from climbing out of feeder cup?? Is there a way to breed and feed off to my chams w/o having to touch them???
