Rodents are charged according to the rodent control area, environment and requirements, and the cost is about 0.50 yuan per square meter-1.5 yuan. If it is a simple rodent control environment, it is ok to use electronic equipment such as rodent repeller, but if the area of hotels, supermarkets, hospitals, hotels, warehouses and other environments exceeds 1000 square meters, professional companies are needed to do the engineering construction. There is a relatively formal pest control company in Guangfuqiao Street 14, Chengdu-that is, "Miller High Electronic Cat Shop". The telephone number is 028-86060085. I will negotiate with my boss myself. The building where our company is located is based on the company's elimination of four evils. You can search the company's website in Baidu.
