A method of collecting the eggs of Micromus tasmaniae, an insect predator for use in the mass production of the eggs needed for field release trials. Prior tests conducted in the laboratory showed that a solution of sodium hypochlorite (NaClO) at either 0.75% or l.00% concentration did not have detrimental effects on egg hatch after immersing them for 6 or 10 minutes, respectively. Seventy-five percent of the eggs were removed from the cloth substrate and 95% of them hatched. Sodium hypochloride at 5% concentration caused the failure of all the eggs to hatch but all of the egg were easily removed from the substrate. This method had reduced egg damage and collection time as compared to the conventional method whereby each egg was collected one by one
