For rodents and other protected areas to eradicate rats, the first thing to do is to use appropriate food. Because the protected rats have a lot of food sources, the average bait such as wheat, corn and other mice do not like to eat. The peanuts of the year should be used as baits and be mixed with rodenticide such as brominaster or bromadiolone. To prepare bait, press the 1:9:90 (medicine: water: bait) ratio and pour the medicine into water first. Stir it evenly, then slowly pour the medicine into the bait and stir it. The bait will make the medicine completely. After absorption, a poison bait containing 0.005% of active ingredient is formulated. Place the poisoned bait in a dry place for about 5 hours to dry. Rodent control in the greenhouse is best to use the "poison bait station" rodent control method, the so-called "poison bait station" is to put the bait into a long cylindrical container, you can use the Coke bottle will be cut at both ends made bait box, will do The good bait box is placed in the greenhouse and placed in the direction of the furrows. Then the mixed peanut bait is placed in the bait box. If there is a heavy rat damage in the 1 mus of greenhouse, three bait boxes can be placed on average. Distribution can be. In this way, rodents can be rodent in the shed all the year round, and the bait should not absorb moisture and deteriorate, which can effectively control the damage of the protected rats. In addition to chemical rodents in greenhouses, poison baits should be placed outside the greenhouse. Or put mousetraps around the shed, place them every 5 meters, and use peanuts as bait, which can effectively control the damage of rats and prevent the migration of rodents from other plots into the greenhouse.
