Microswimmers navigating narrow channels face delays when encountering others moving in opposite directions. These delays can cause microswimmers to accumulate and form clusters that block the entire channel. Here, the authors use a kinetic theory incorporating effective displacements obtained from experiments with soil bacteria, to predict the critical densities for cluster formation.
