Abstract: Objective Study the indoor ground free flea control method to prevent occurrence and epidemic of mouse transmission diseases. Methods Using composite-formulated fast fleacide instead of the traditional method of applying a single fleacide,and successively spraying the fleacide twice,each 50 ml/m² (ground not absorbing water) or 100 ml/m² (ground absorbing water). Results In this study total 8 observation points were set up. After the application,the flea positive index (%) of #1,#6 and #8 observation point was reduced from previous 1.967 ,0.267 and 0.167 to 0.007 ,0.020 and 0.007 respectively and the flea-killed ratio(%) was 99.64 ,92.51 and 95.81 respectively. After the application,the flea positive index (%) of #2,#3,#4,#5 and #7 observation point was reduced from previous 0.153 ,0.133 ,0.740 ,0.120 and 0.187 to 0,and all flea-killed ratios (%) were 100. The mean flea-killed ratio(%) of 8 points is 98.98 . Conclusion Using composite-formulated fast fleacide and the applying method of successively twice spraying to consolidate the flea-killing effect gets satisfied results and this method should be popularized in similar areas and under similar environments.
