Abstract:

Objective To observe the role of ecological approaches to deratization in keeping the rat density in large hotels as low as possible, providing a scientific basis for future deratization. Methods First, 0.005% bromadiolone corn poison bait was laid out for 6 consecutive days in the four large hotels with similar environmental conditions and serious rodent damage. And then the 4 hotels were randomly divided into two groups, of which ecological approaches to deratization were followed in one, with the other used as the control group. S-100 method was used to evaluate the deratization effect by the deratization rate based on the difference in the rodent density between the 2 groups within 6 months. Results The deratization rate of 0.005% bromadiolone corn poison bait for the 4 hotels was 96.92%, 97.06%, 96.82% and 97.53%, respectively, with the overall deratization rate being 97.12% within the 6 months. By the end of the observation, the rat density of the 2 hotels in the test group increased only by 2.97 compared with that at the time when corn poison bait deratization was completed, while the density of the 2 hotels in the control group increased by 34.34 in the same period of time with a difference of 31.37 between the two groups(u=22.24, P<0.01). Conclusion The deratization effect with poison bait followed by ecological approaches is a highly effective means for safe deratization and prolonged maintenance of the state.
