A clean terrarium is key to keeping your reptiles happy. Of course, this isn’t the most glamorous of tasks, even if it is a part of regular maintenance. But what if we told you that you could save time and cut back on time spent cleaning with the introduction of a few simple species?
A terrarium clean-up crew can help boost your ecosystem as well as maintain cleanliness. No matter if you’re new to caring for reptiles and need an easy solution to help keep your terrarium thriving, or if you’re an expert looking to cut back on cleaning time, in this blog, we’re going to take you through what clean-up crews are, their benefits and how to introduce them into your tank.
Before we get started, it’s important to note that this guide is designed with glass terrariums in mind. We do not recommend implementing clean up crews in wooden vivariums, as certain clean up species will eat damp wood.
What is a terrarium clean-up crew?
A terrarium clean-up crew is a group of small, beneficial organisms, such as springtails and isopods, added to an enclosure to help maintain cleanliness and ecological balance. Instead of manually removing every bit of waste, these tiny creatures do the job naturally by breaking down organic matter like dead plant material, uneaten food, animal waste, and even mould, helping to save time for owners.
The benefits of terrarium clean-up crews
There are many benefits of terrarium clean-up crews (aside from helping you save time and energy), for example, they act as decomposers, recycling waste into nutrients that can be reused by plants in the terrarium. This process not only keeps the enclosure looking clean but also helps prevent harmful bacteria and fungal overgrowth. Bigger clean-up crew species, such as isopods, can also help encourage natural foraging and hunting in your reptiles, which is great for improving their quality of life and overall happiness.
What types of terrariums can have clean-up crews?
Any type of terrarium can have a clean-up crew; however, they work best in a balanced, bioactive environment. Tropical terrariums are ideal for clean-up crews due to their temperature and soil substrates. Desert-themed terrariums are more challenging (but not impossible) due to low humidity, and typical clean-up crew members may struggle to survive. However, certain hardy isopods and beetle larvae can be used if there are small pockets of moisture within the substrate.
Basically, it’s all about finding the right species of clean-up crew for the type of terrarium you have. Once you have this knowledge, it becomes easier to create this ecosystem in your terrarium.
Remember, in terms of ‘type’ of construction material, clean-up crews are not suitable for wooden vivariums. Always choose a glass or plastic terrarium.
Types of terrarium clean-up crews and their uses
There are many different species of clean-up crew that you can include in your terrarium, and each species offers different benefits. For this reason, it can be good to keep a few different types of clean-up species to cover all the bases. Below, we’ve included some of the main clean-up crew options, their benefits and what individual jobs they perform.
Springtails
Springtails are the most common choice for terrarium clean-up crews. They’re tiny white invertebrates that work to break down mould, animal waste and organic matter. They usually come in a tub as a culture, but they’ll need time in their new environment to properly colonise. This means you’ll have to wait a while before adding your pets; the springtail colony may not be big enough to handle the waste load if you add them too early.
You should also be mindful of keeping smaller species such as poison dart frogs, which may see the springtails as a food source. Springtails do best in warm atmospheres, so they thrive best in humid, tropical environments, but they can handle arid set-ups as well, given that they have a humid area to retreat to.
Isopods/Woodlice
Another popular choice for clean-up crews are isopods, or more commonly known as woodlice. Tropical woodlice also have the same requirements as springtails, so they’re great for putting together in tropical environments. Woodlice are great for cleaning up leaf litter, decaying plants, animal waste and shed skin.
You can also get some very interesting species of woodlice to use in your clean up crew, which only adds to the environment. You’ll need to make sure though that for your clean-up crew to work effectively, you have plenty of leaves and hiding places for them to retreat to to avoid your reptiles from preying on them too heavily.
Earthworms
Earthworms such as the Dendrobaena earthworm are small compost worms that not only feed on waste, but also move through lower levels of soil, keeping soil moving and aerated and preventing stagnant areas. They also help with nutrient cycling, taking waste and redistributing essential minerals and nutrients within the terrarium soil. They also have the added bonus of encouraging foraging behaviours in your pets, which is great for stimulation.
Dendrobaena earthworms are well-suited to a tropical climate; however, if your terrarium fosters a colder climate, then we would recommend giant lob worms, which thrive in colder environments.
Beetles
Perfect for dried, arid setups, beetles such as blue death-feigning and dermestid beetles make valuable contributors to your terrarium. Beetles can break down a wide range of organic matter, from dead plant material to animal remains, facilitating nutrient recycling. While they are slightly less effective with waste management than other clean-up crew options (they usually prefer a greener diet), they are very effective at pest control as some predatory beetles prey on potential pests, such as fruit flies and aphids - helping keep your terrarium clean and balanced.
Millipedes
Millipedes make a great addition to any terrarium clean-up crew. They take waste such as dead leaves, wood, and plant debris, and turn it into nutrients for the soil. These nutrients keep plants thriving and healthy. In addition, they help aerate the soil by burrowing. Good species for a bioactive terrarium include African giant millipedes and bumblebee millipedes.
Do you still need to manually clean a terrarium with a cleanup crew?
Yes, you should still do manual cleaning even with a cleanup crew because your crew can only do so much. They’re not a replacement for cleaning, just an extra helping hand. Clean-up crews handle ongoing small-scale waste issues, but will need help when it comes to larger waste clean-up. You’ll still need to do regular maintenance for things such as:
- Removing large waste items (e.g. big food leftovers or heavy soiling)
- Cleaning glass and décor for visibility and hygiene
- Monitoring mould or pests in case something gets out of balance
- Doing occasional substrate spot-cleaning if waste accumulates faster than it can be broken down

When should you introduce your cleaning crew?
You should introduce a clean-up crew only after your terrarium is properly established, not right at the start. Timing is key because these tiny organisms rely on a stable environment to survive. Here’s a good timeline:
- Set up the terrarium - Add substrate, plants, décor, and any other features. Make sure everything is arranged and the enclosure is fully functional.
- Allow the environment to stabilise - Let the terrarium run for 2–4 weeks (sometimes longer for tropical setups) so moisture levels, temperature, and microfauna populations like beneficial microbes are consistent. This is a good time to introduce your leaf litter also. We’d recommend using a mixture of dried mulberry and catappa leaves for added nutrition.
- Check for mould or excess moisture issues - Ensure that conditions won’t harm your clean-up crew. Sudden spikes in humidity or extreme dryness can be fatal to them.
- Introduce the clean-up crew - Add your springtails, isopods, or other chosen organisms. They’ll now have a stable substrate and plenty of organic material to start thriving.
Introducing them too early, before the ecosystem is ready, can result in high mortality and reduced effectiveness. A stable terrarium gives your clean-up crew the best chance to establish themselves and start doing their job effectively.
We would recommend using an isopod habitat kit such as the Zoo Med Creatures Roly-Poly Kit. This will allow you to cultivate the isopods until they’re ready to be introduced to the enclosure, they can breed inside this small container and then be added to the terrarium.
Zoo Med Creatures Roly Poly Isopod Habitat Kit with Substrate - £25.99
In terms of substrates, make sure you pick an appropriate material. If you’re unsure we’d recommend the ProRep Bio Life Forest Substrate, Arcadia EarthMix & EarthMix Arid Reptile Bio Active Soil Substrate or Pettex Tortoise/Reptile Substrate.
ProRep Bio Life Forest Substrate 25 Litre - £32.95
Arcadia EarthMix & EarthMix Arid Reptile Bio Active Soil Substrate 5L - £6.50
Pettex Tortoise/Reptile Substrate 10L - £4.95
You should also add them before introducing any bigger animals, as they need time to colonise and grow so they can handle the waste load.
