To add springtails successfully, the terrarium needs to be damp, sheltered and already supplied with leaf litter, cover, airflow and organic matter. Once those basics are in place, you can introduce the culture and let the colony settle into the moist areas of the enclosure.
For related setup and care topics, see our Springtail Bioactive Guides and our page on Springtails for Bioactive Enclosures.
What springtails need before you add them
Springtails do best in a terrarium that already has a damp substrate, a layer of leaf litter and some form of cover such as moss, bark or planted structure. They also need some airflow and enough organic matter to feed on and move through. The aim is a stable, moist enclosure with sheltered pockets, not a flooded or sealed environment.
If you are deciding how large a culture to use, our guide on How Many Springtails Should You Add to a Terrarium? gives a useful starting point.
How to set it up
1. Make sure the terrarium is already prepared with damp substrate, leaf litter and cover. Springtails settle best when there is somewhere moist to move into straight away.
2. Open the culture and check what it is carried on. If it arrives on charcoal, substrate or another carrier material, add that material to the enclosure as well.
3. Tip or place the culture into a damp area of the terrarium, ideally where leaf litter and substrate meet. If the enclosure has more than one suitable moist zone, you can spread the culture between them.
4. Leave the terrarium undisturbed so the springtails can move into hidden damp areas and begin establishing. They usually spread fastest where moisture and organic matter are already present.
5. Keep feeding light. In a bioactive setup, the existing leaf litter and decaying matter are often enough to get started. If you are maintaining a separate culture, add food gradually rather than in large amounts.
Springtails do not need constant handling after introduction. Once they are in the enclosure, the main job is to keep the habitat stable enough for them to stay active in the damp zones.

What to check before use
Before you rely on the terrarium to support springtails, check that it has the right conditions in place:
- Damp substrate below the surface
- Leaf litter, moss or other cover to hold moisture and provide shelter
- Organic material available for feeding and microbial growth
- Some airflow, so the enclosure does not stay stagnant
- A fresh, earthy smell rather than a sour or swampy one
If those points are in place, the enclosure is usually ready. Springtails may stay mostly hidden, but they should be able to move through the damp areas and establish without the terrarium becoming waterlogged or drying out too quickly.
