hi all, I recently noticed whilst feeding my tarantulas that my feeder roaches bedding has grown green mould like bread if you leave it out to long, I failed to realised that wheat-bix /Wheaties will mold easily over time but now that its happen should I really be that concerned or are roaches hardy enough to survive the epidemic , also down in Aus the feeder roaches are wood roaches but i don't know how broad that is and i don't know the scientific name sorry.
