Hi, for dubia bins make sure you have adequate airflow, feed high protein grains regularly and veggies/fruits several times a week to cut down on excess water/humidity. This also allows the roach frass to be drier. The Roach bin Cleaner Crews are a special mixture of 2 types of larvae & beetles that feed exclusively on protein or dead roaches. The other 2 types of beetles & Larvae feed solely on grain. Together they will consume any dead roach, excess grains and remove water from veggies or fruit before spoiling or molding.

Our Isopods are also great decomposers so they work great as Roach Bin Cleaner Crews. A sizeable colony can eliminate a dead roach in hours before smell sets in they are also Much better with the veggies as they readily eat that which is decaying.

Springtails like Isopods are also great decomposers and are great for clearing vegetable matter and they also love to eat mold so no mold worries once the springtails set in. I would recommend the 2 tropical species we carry, Tropical Springtails as well as the Tropical Pink Springtails. Temperate Species will be ok though you may find they do not reproduce so readily in dubia, this is fine depending on the quantities that you need. Temperate species should be cultured outside the tank and added when appropriate whereas you can just add tropicals and they will continue to thrive and reproduce.

Hope This Helps
