Abstract: (71 Views)
Background and Objective: Due to the lack of the desirable methods of rodent control, the construction of an intelligent rat trap that injects environmentally friendly poison was considered as an effective solution.
Materials and Methods: Based on studies of the length, weight and behavioral characteristics of various types of mice, the initial design of the device was carried out. Using walnut and hazelnut oils, the mouse was guided toward the death tunnel, and the desired chemical was automatically injected into the mouse's chest. The device was first tested with laboratory mice and then with wild samples, and design flaws were examined and resolved at each stage. Data analysis was performed using the chi-square test.
Results: In the death section, two substances—sodium chloride and EDTA—were tested at a concentration of 1 Molar with volumes of 1 mL and 2 mL, respectively, at distances of 2, 4, 6, and 8 centimeters from the rat muzzle. EDTA with a volume of 2 mL achieved a 97% mortality rate (confidence interval 88-99 with a 5% margin of error) at 8 centimeters from the rat muzzle and with an exposure time of 20 seconds. Regarding the comparison between walnut and hazelnut flavors, walnut flavor received the highest attraction score of 93% (confidence interval: 84-98), making it the best parameter in the design.
Conclusion: Due to its ease of use, independence from users’ skill, and environmentally friendly procedure, this method of controlling rat populations is considered an effective, sustainable, and intelligent solution.
