Abstract: Objective:To study the rodent control technology and methods in the outer environments of the city,Shanghai.Methods:Using bait expending in the our environments(residence area,food market,discard construction site) to observe the result(rate of bait expending) which the bait put in vary container,which the bait put in container and in out-container and which the vary bait(grain,cereal,wax) put in the same container.Result:The rate bait expending of three way(put bait in container,put the packing bait in ground and put the no-packing bait in ground) has difference(χ²=273.39,P<0.01).The rate bait expending of the bait in container is situated between put the peaking bait and no-peaking bait in the ground.The rate bait expending on bamboo container higher than plastics container(χ²= 7.43,P<0.01),but it was not difference with brick container(χ²=0.82,P>0.05).The result of cereal bait and grain bait put in the container is excellence than wax bait from short time.The wax bait and small packing bait were good methods in moist building-out for long time.Conclusion:The rodent control in the outer environments should be using bait box(bait station) and wax,small pecking bait.
