2. Biological deratization. Protect the natural enemies of rats, such as owls, weasels, badgers, cats and most snakes that feed on rats, so as to control the number of rats.
3. Control rodents with instruments. Catch mice with mousetraps and cages. This method is not suitable for large area or high density mice.
4. Drugs kill rats. This method has good effect, quick effect and wide application range, and it needs to kill rats in a large area. However, attention should be paid to the selection of rodenticide with high efficiency, low toxicity, low residue, no pollution and low risk of secondary poisoning, which will not cause physiological drug resistance in rats. (rodenticide, carbendazim, diphacinone sodium salt, toxic rat phosphorus, Dalong, if it doesn't work, please wait a little longer. )
5. Use 0.005% bromadiolone bait: Bromadiolone is the second generation anticoagulant rodenticide, which has good effect on farm rodents and domestic rodents.

2. Making bamboo tube bait station: made of bamboo tubes with a diameter of 5-6 cm. The poisonous bait station in the building area is 30cm long, and the farmland area is 45cm long (excluding the protruding part for shelter from rain). Poison bait stations usually put 25-30 grams of poison bait. Check once every 15 days to make up for the decrease of poison bait.
3. Poison bait station placement: the farmhouse is placed directly on the wall root and fixed with pebbles, two for each household, one outside the pigsty and one under the back eaves. When used in the field, the bait station should be fixed and inserted into the ground with iron wire, and 3-5 cm should be left between the ground and the bamboo tube to prevent rainwater from pouring in. 1 poison bait station is placed per mu and along the ridge. The deratization time shall not be less than 20 days, preferably 30 days.
4. Precautions: When preparing poison bait, it should be carried out in accordance with the prescribed operating procedures. The place where poison bait is prepared should be far away from water sources and livestock and poultry. Don't touch the bait with your bare hands. The remaining poisons and baits should be recovered and kept in time. Poisonous bait, toxic garbage and collected rat carcasses that are no longer used should be buried deeply.
