Abstract: Objective To observe the deratization effect with different bait poisons in different bait boxes at different periods of time. Methods On-the-spot test had been carried out with bait poisons in 3 rural areas of Lanshan district, Linyi city, which were in the same environmental conditions. Corn, wheat bait poisons of 0.05% diphacine-Na, and mixed bait poisons were put into 4 kinds of bait poison boxes which were made by wood, fibreboard and cement. S-100 method was used to evaluate the deratization effect. Results The deratization rate was as follows: the deratization rates with mixed bait poisons in trapezoidal boxes with one opening were 66.90% and 97.08%. But in rectangle boxes with one opening they were 73.11% and 95.68%, in wooden triangle boxes they were 83.00% and 99.84% on the 10^th and the 45^th day. The deratization rate with corn bait poison in rectangle cement boxes was 77.74%, 88.82%, 95.93% and 98.97% respectively, in wooden triangle boxes it was 57.87%, 89.67%, 89.57% and 95.35% respectively in the 10^th, 20^th, 30^th and 60^th day. The deratization rate with wheat bait poisons in rectangle cement boxes was 75.02%, 85.55%, 94.43% and 96.69% respectively, but in wooden triangle boxes it was 43.26%, 80.32%, 88.07% and 95.02% respectively on the 10^th, 20^th, 30^th and 60^th day.
