What Are Springtails?
Nature's Smallest Helpers.
One of Bioactive's Biggest Assets.
Published: May 30, 2026
A beginner-friendly guide to understanding one of the most important members of every bioactive clean-up crew.
If you are building a bioactive enclosure, few organisms are more important than springtails.
Although they measure only a few millimeters long, these tiny soil-dwelling arthropods perform an enormous amount of work beneath the surface. Every day they help recycle nutrients, consume mold, support healthy soil biology and contribute to the natural processes that keep an ecosystem functioning.
That is why experienced bioactive keepers almost always recommend adding springtails from the very beginning.
Whether you are creating your first terrarium or maintaining a mature vivarium, understanding how springtails work will help you build a healthier enclosure with less maintenance over time.
Quick Answer
Springtails are tiny white arthropods (Collembola) that live in soil and leaf litter around the world. They feed primarily on mold, fungi, decaying plant material and other organic matter (including reptile waste and byproduct). In bioactive enclosures, they help control mold, recycle nutrients, improve soil health and create a cleaner environment for reptiles, amphibians, invertebrates and plants.
What Are Springtails?
Despite their tiny size, springtails are some of the hardest-working organisms in nature.
They naturally live in forests, gardens, compost piles, and healthy soil where they spend their lives breaking down organic matter and feeding on microscopic fungi and molds. In fact, a single handful of healthy forest soil may contain hundreds (or even thousands!) of springtails quietly doing their job beneath the surface.
Because they already perform these important jobs in nature, bioactive keepers intentionally introduce them into terrariums and vivariums to recreate those same natural processes inside an enclosure.
Rather than cleaning the enclosure yourself every day, springtails become part of a living ecosystem that helps maintain itself, creating your own closed loop mini ecosystem.
Are Springtails Insects?
Although they look similar to tiny insects, springtails actually belong to a separate group of arthropods known as Collembola. Scientists once classified them as insects, but today they are recognized as their own distinct lineage.
Most species measure only 1–3 millimeters long (tiny little guys!), making them easy to overlook until their population begins to grow.
One of their most recognizable feature is a small forked structure beneath their abdomen called a furcula. When disturbed, they can release this structure like a spring, launching themselves into the air, hence the name Springtail.
Fortunately, the species most common and sought after for bioactive enclosures and terrariums, Folsomia candida (white springtails), rarely jump very far and spend nearly all of their time within the soil. Especially since you are creating an ideal bioactive environment for them, they are not going to want to wander too far.
Why Are Springtails Important in a Bioactive Enclosure?
If there is one organism that quietly keeps a bioactive enclosure running behind the scenes, it is the springtail.
While reptiles, amphibians and isopods often get the attention, springtails spend every day performing the small jobs that help keep an ecosystem healthy.
Their primary role is to consume mold, fungi, decaying organic matter and microscopic waste before those materials have a chance to build up. As they feed, nutrients are naturally recycled back into the soil where plants, beneficial microbes and other organisms can use them.
Rather than relying entirely on routine cleaning, bioactive enclosures depend on millions of natural biological interactions. Springtails are one of the smallest members of that system. They quietly perform essential work every day beneath the surface where most keepers never see them.
Isopods do a lot of the heavy lifting, acting as the vacuum cleaner and picking up a lot of the big waste products. Whereas springtails serve as the broom and dustpan, working closely with the isopods to pick up anything they may have left behind.
Instead of constantly cleaning mold or worrying about excess organic debris, you are allowing biology to do what biology has done for millions of years.
This is one of the biggest reasons bioactive enclosures require less maintenance than traditional setups and are gaining the attention they much deserve.
Nature Already Has a System
One of the biggest misconceptions about bioactive keeping is that success comes from buying more products.
In reality, success comes from recreating the natural biological processes that already exist in Mother Nature.
Healthy soil is full of life. Springtails, isopods, beneficial microbes, fungi and countless other organisms each perform a different job. Together, they break down organic matter, recycle nutrients and help maintain a balanced ecosystem.
A bioactive enclosure follows that same blueprint.
Rather than relying solely on routine cleaning, a healthy enclosure allows biology to do much of the work naturally. Springtails are one of the smallest members of that system, yet they make one of the biggest contributions.
We believe thriving ecosystems begin with real biology.
What Do Springtails Eat?
Springtails are detritivores by nature, meaning they feed on decaying organic matter rather than healthy plants or animals.
In a healthy bioactive enclosure, their diet commonly includes:
-
Mold
-
Fungal growth
-
Decaying leaves
-
Dead plant material
-
Organic waste
-
Microscopic bacteria
-
Biofilms
Healthy springtails do not damage live plants, attack reptiles or harm isopods. Instead, they work symbiotically with their surroundings to create an ideal and healthy environment to thrive in.
They are interested almost exclusively in the microscopic food sources naturally found within living soil, which is another reason why having a truly nutrient-dense soil makes a substantial difference in the overall health of your tank.
Do Springtails Really Eat Mold?
Yes...and that's one of the biggest reasons bioactive keepers love them!
It is important to understand that springtails will not magically eliminate every mold outbreak overnight. Instead, they help keep naturally occurring mold populations under control as part of a balanced ecosystem.
When combined with the proper ventilation, appropriate moisture levels (think of moisture as the Goldie Lock approach - not too wet, not too dry), quality substrate and isopods, springtails become an incredibly effective biological clean-up crew.
Rather than treating mold with chemicals (which we would never recommend) or constantly replacing substrate ($$$$$), you are allowing nature to restore balance naturally.
That is exactly what bioactive keeping is all about.
Do Springtails Breed?
Of course!
With the proper moisture, food and stable temperatures, white springtails (Folsomia candida) reproduce readily inside bioactive enclosures.
This is actually one of their greatest strengths!
Instead of purchasing new clean-up crews every few months, healthy springtail colonies naturally maintain themselves by producing new generations over time...and at a quicker rate than you may think!
A thriving springtail population is often a sign that your bioactive enclosure is healthy and functioning as intended.
Why Rubber Ducky Isopods' Springtails Are Different
We believe healthy bioactive ecosystems start with healthy biology. That is why we focus on producing thriving cultures that are ready to establish themselves as soon as they arrive.
Unlike many springtail cultures that are shipped on charcoal, our white springtails are raised in a nutritious substrate that better supports long-term colony health and reproduction. Each culture is actively fed with our own Superfood created here at Rubber Ducky Isopods, helping produce healthy, well-established populations before they ever leave our facility. We also ensure to continually add varied genetics to keep the breeding lines strong.
Every order is carefully packed with insulated packaging, temperature protection and properly marked exterior packaging signaling to the shipping carriers that live animals are inside.

Will Springtails Escape?
This is one of the most common questions we hear, especially at Reptile Expos and Plant Expos.
The good news is that healthy springtails prefer the exact conditions found inside a bioactive enclosure: consistently moist soil, leaf litter, organic decomposing waste product and humidity.
If they happen to wander onto dry surfaces outside the enclosure, they quickly lose moisture and usually will not survive for long. Because of this, established colonies naturally remain where conditions are best, right within the bioactive enclosure that you have created.
In other words, if your enclosure provides the environment they need, your springtails generally have no reason to leave it.
Can Springtails Live with Isopods?
Absolutely - and we live for the combo!
In fact, springtails and isopods are one of the most successful partnerships found in bioactive keeping.
Springtails spend much of their time feeding on microscopic fungi, molds, biofilms and organic debris within the soil (broom and dustpan).
Isopods typically consume larger pieces of decaying leaves, wood, organic matter, and leftover food (vacuum).
Together, they create a diverse clean-up crew that processes waste more efficiently than either could alone. This natural partnership is one of the reasons nearly every successful bioactive enclosure includes both springtails and isopods.
Are Springtails Right for Every Bioactive Setup?
Honestly, we have never heard of a situation where that wasn't the case.
Whether you are building a tropical terrarium, dart frog vivarium, gecko enclosure, snake habitat or planted isopod culture, springtails provide long-term benefits by supporting healthier soil biology and helping recycle organic waste.
Even experienced keepers often consider springtails one of the first organisms to introduce into a new bioactive enclosure because they begin establishing the biological foundation from day one.
For beginners, they are also one of the easiest additions you can make. Once introduced into suitable conditions, they require very little maintenance and often establish self-sustaining populations.

Frequently Asked Questions
Can you see springtails?
Yes. Adult white springtails are small, typically measuring between 1 and 3 millimeters in length. They are easiest to spot on moist soil, beneath cork bark, or when food is added to the enclosure.
How many springtails should I add?
For most enclosures, a single healthy culture is an excellent starting point. Given the proper moisture, food and environmental conditions, the population will naturally grow over time.
Are springtails safe for reptiles and amphibians?
Yes! Springtails are completely harmless to reptiles, amphibians, tarantulas, invertebrates, and live plants. They spend their lives within the substrate feeding on microscopic organic material.
Can springtails survive without isopods?
Absolutely. Springtails can establish healthy colonies on their own. However, they complement isopods extremely well because each contributes differently to the biological processes within a bioactive enclosure.
Why do some springtail cultures arrive on charcoal?
Charcoal has traditionally been used in the past because it is lightweight, inexpensive and retains moisture. At Rubber Ducky Isopods, we focus on producing thriving, well-fed colonies rather than simply shipping springtails in a familiar medium. Your cultures from us will never arrive on charcoal.
Do springtails need additional food after I add them?
Once established inside a healthy bioactive enclosure, springtails often find many natural food sources. If you are culturing them separately, supplemental feeding helps maintain a strong, productive colony.
How long do springtails live?
Individual springtails typically live for several months. Healthy colonies continuously reproduce, allowing the population to sustain itself for years under the right conditions.
Are springtails worth adding to a bioactive enclosure?
Without question. They are one of the simplest additions you can make, yet one of the most valuable. Their ability to support soil biology, recycle nutrients and assist with mold management makes them an essential part of nearly every successful bioactive enclosure.
