It has been described to live in various terrestrial habitats and is often associated with compost, dung, mud, other decaying materials and different kinds of beetles.

Mononchoides composticola became dominantly present in the studied compost heap.

It has the ability to actively move towards bacterial food resources such as Achromobacter species.

This means that M. composticola has a dual feeding behavior and can alternate between bacterial and nematode prey.
