Springtails mainly feed on fungi, bacteria, biofilm, algae and fine decaying organic matter. In bioactive enclosures they often graze on what develops naturally; in dedicated cultures, they may need a small amount of supplementary food to keep the colony active. The best approach is usually light feeding, because springtails are more likely to stay healthy when food is used up quickly rather than left to rot.

For broader background, see our Springtail Feeding & Culture Food Guides, including What Do Springtails Eat? and How to Avoid Overfeeding Springtails.

What do springtails eat?

Most commonly kept springtails are generalist feeders. They graze on fungal growth, microbial films, biofilm, algae and tiny particles of decaying organic matter. In established cultures and bioactive enclosures, those food sources often develop naturally on leaf litter, bark, moss and the substrate itself.

In bioactive setups, that natural grazing is usually enough for the colony to keep going. In dedicated cultures, there may be less natural food available, so a small amount of supplementary feeding is often useful. Simple foods that the colony can reach and consume quickly are usually the easiest to manage. Our Springtail Food - Yeast & Oat Mix is one option designed for feeding cultures, and our Springtail Food & Culture Supplies collection brings together practical items for routine maintenance.

Some species are broad generalists, while others are more specialised, so the right food and feeding pattern depends on the species and the setup. If you are keeping a species with specific needs, follow species-specific guidance first.

How often to feed

There is no fixed schedule that suits every culture. Colony size, temperature, moisture, airflow and the amount of natural food already present all affect how quickly springtails use what is offered. A small starter culture may need only tiny additions, while a larger or more active colony can clear food much faster. Bioactive enclosures often need less frequent supplementation because they already provide ongoing grazing material.

The practical rule is simple: feed sparingly and wait until the previous food has been used before adding more. Small, regular amounts are easier to manage than large meals and make it easier to see how the colony is responding. In bioactive enclosures, extra food should be occasional and kept minimal so it supports the system without creating waste.

Signs the routine needs adjusting

Watch the colony itself. Springtails usually make it clear whether the feeding routine is about right.

Signs the current routine is working:

• Food is being consumed steadily rather than sitting untouched


• Springtails remain active across the culture or enclosure


• The culture smells fresh or neutral, not sour or stale


• Moisture stays stable without obvious breakdown of the setup


• The population appears to be holding steady or slowly increasing

Signs you may be overfeeding:

• Food is left over for long periods


• Visible mould spreads quickly around the food


• The culture develops a sour, off or fermented smell


• Mites or other unwanted hitchhikers become more noticeable


• The substrate looks messy or overly wet around feeding spots

For a closer look at this problem, see How to Avoid Overfeeding Springtails.

Signs you may be underfeeding:

• The colony seems active but growth is slow for a long period


• Natural food sources are scarce in the culture


• Supplementary food disappears very quickly and the population remains stable rather than expanding


• Individuals seem to cluster around the few available food spots

If the colony is healthy, increase the amount a little and watch how quickly it is used. Adjust gradually, and let the culture tell you whether the routine needs to change.
