Product Details

In our experience, the combination of Dermestid beetles and lesser mealworms make better cleaner crews than either insect alone. Any weakness in one species is complimented by the strengths of the other. In the end, the whole is greater than the sum of its parts. When it comes to cleaning roach colonies, Combination Cleaner Crews work cooperatively, not competitively. And the result is symbiotic.

Each Combination Cleaner Crew kit has enough of each insect to establish a colony, given the right conditions. If you have a successful Dubia roach colony, these conditions will most likely be met, and the main factor will be food supply.

How It Works

Both cleaner species (dermestids and lesser mealworms) enjoy a symbiotic relationship with Dubia roaches. This relationship works to their mutual advantage, and their proximity is a win not just for the insects, but for you as well.

In return for becoming food for Dermestes after they die, Dubia roaches enjoy tidier surroundings, better health, and a higher survival rate. And in return for clearing debris, Dermestid beetles and larvae get a reliable food source that increases over time as the colony’s population grows. The colony’s growth fuels their own population growth, creating a positive cycle. The Dubia’s success is the Dermestes’ success, and visa-versa.

On the other side of this equation, lesser mealworms work in the background, eating discarded food particles in frass. This reduces moisture and helps prevent bacterial overgrowth. There is also a positive cycle here relating to frass and food. More roaches means more frass, and more frass means food for the mealworms.

How Many Kits Do You Need?

While the number of cleaners in the Kits may seem small, they are proper for the job at hand for several reasons. First, these insects can do a lot of work. A few Dermestid beetles or larvae can process a roach carcass in just a couple of days. Second, people tend to overestimate how many cleaner insects they need. More is not always better.

The right amount is the number the natural die-off in the colony can sustain. It is best to start with only the number of cleaner crews a colony can support. Without food, they will simply die off, and these insects reproduce fast when food is abundant. If there isn’t enough food to fuel population growth, they will wait until there is enough.

Combination Kit Capacities

This is to give you an idea of the cleaning capacity of Combination Cleaner Crews right out of the box. It’s roughly the number of Kits a colony of a certain size might need for immediate full cleaning capacity. It’s not the number you need for a certain colony size. You can start with one if you like. They will reproduce at a rate dependent on the food supply.

Roaches/Bin Size# of Kits
0 – 500 & bin up to 4 sq.ft.1
500 – 1,000 & bin up to 4 sq. ft.2
1,000+ & bin up to 4 sq. ft.3
0 – 500 & bin > 4 sq. ft.1
500+ & bin > 4 sq. ft.2

Each Kit contains a roughly equal mix of Dermestids and lesser mealworms in a quantity that will help you establish a cleaner colony as outlined above.

Because each insect picks up where the other leaves off, combining these two species provides a significant boost in cleaning capacity compared to either alone. Of course, this doesn’t mean you can neglect your roaches. You still have to check in from time to time to see how they’re doing. And cleaner crews require some care, too. Though the effort is small and infrequent, it’s still good to know what they need, how they work, and what to watch out for.

In addition to the benefits outlined above, adding Combination Cleaner Crews can slow or stop the build-up of moisture and bacteria in a Dubia roach colony. They make the job of cleaning and caring for Dubia roaches much easier. Your mileage may vary based on your location and environment, but we are happy with this combination in our own Dubia colonies.

NOTE: While typically right at home in Dubia colonies, either cleaner species could be considered a “pest” in certain circumstances. We’ve never heard of any problems from roach-keepers, but it can’t hurt to understand the potential risks.

    Bugs arrived on time and alive. They are already going to work in my colony. Definitely recommend and will be purchasing again.

    I love these guys. My colony is bigger than I realized, so I’m going to be adding another set soon.

    Janelle – May 5, 2023

    I think most of my Dermestid beetles made it, but it was chilly here the day they arrived (sudden drop in temps) and while everyone seemed alive when I put them in the habitat, I ended up losing all of my mealworms overnight. I think the Dermestid beetles are helping a bit, but I may end up getting another cleaner crew in the future. My roach colony (arrived in the same package) is thriving though, so no complaints here! Thanks guys!

    Kara – March 27, 2023

    My colony was growing too rapidly for me to keep it as clean as I would like it to be. These did the trick. The colony is doing great and it’s less maintenance for me. The crew arrived in good shape. Everyone was live, healthy, and ready to go straight into my colony!

    Fast shipping. Active bugs. So far everything seems good. I introduced a few to our colony to start just to see how things go.

    These have been amazing! We had a mild fly issue that came with my roach colony that I purchased from an acquaintance. A little cleaning and this clean up crew has things back in order.

    These cleaners arrived today and all were in great shape and very active. I couldn’t be happier. Shipping was fast and they were packaged very well. Thanks!

    Jason – January 29, 2018

    These beetles made a big difrence in my Dubia colony. They cut cleaning at least in half. I clean less often and the frass stays dry where before it was wet. I never thought cleaner crews mattered much. Now I highly recommend them.
