Abstract: The paper reprots firstly the elimination of rodents by means of filling the burrows with slurry, tests were done indoors in the villages of Wucheng county, Shandong province from November, 1990.Two portions of soil and one portion of water were mixed and stirred in a container until they became slurry, which was to be used to fill the rodent burrows. The burrows were firstly blocked with wet soil, of which 295 re-excavated by Rattus norvigicus then filled with slurry (each burrow averageing about 20 liters)Observations on three groups of experiments for 3～5 days revealed no re-excavated burrows, showing 100 percentage of burrow blockage. The corrected rodent elimination rate of the three groups measured with powder-spot method was 96.16, 81.13 and 78.83%, respectively.We believe that the method is very economic and worthy of promotion because it can be done any where and any time by anyone with local materials. It may be taken as the main method of rodent elimination in certain area.
