The work was carried out with the aim of seeking effective methods of collecting fleas from the burrows of midday gerbils and Tamarisk gerbils during epizootological investigations of sandy sectors of the natural plague focus in the Volga-Ural interfluvial area. A check under practical conditions fully supported the feasibility of using flannel plait for the mass collection of fleas from gerbil burrows and the advantages of this method. The plait was inserted up to 70 cm into the burrow and left there for 5 seconds, during which time it was moved around a little. Then it was removed in order to collect the fleas from it and again put back into the burrow. It was established that one worker in one working day, even if there was a small number of gerbils, could investigate more than 150 burrows with the plait by this method.
