How to kill rats and insects in pig farms.

Killing rats, flies and blood-sucking insects is also one of the important measures to reduce vectors, prevent epidemics and ensure the health of pigs. The whole pig farm should be deratized once a month, especially in the feed bank to prevent rats from entering and leaving; According to the season and farming season, the work of killing flies and mosquitoes should be carried out regularly.

(1) deratization

① Strengthen feed management and environmental management: the walls, floors, doors and windows of the pigsty should be solid and firm, and the rat holes should be blocked in time when found. Pig feed should be put in a warehouse where rats can't get in. We should always keep the pigsty and its surrounding environment clean and tidy, clean up the scattered and redundant feed in time, eradicate weeds in the environment and try our best to clear the breeding ground of rats.

② Rodent killing method: it can be killed by instruments or drugs. According to the local conditions, you can choose mousetraps, mousetraps and mousetraps to kill rats. There are many kinds of rodenticides, such as diphacinone sodium salt, spironolactone, rodenticide, etc., which have low toxicity to people and animals and good effect. For example, dissolve 1.5g diphacinone sodium salt in 100 ml hot water, then add a proper amount of sugar and soak it in1000g corn, wheat, rice, etc. , and dry in the shade before putting into use. Poison bait should be placed in a safe place for people and animals.

② Killing flies and mosquitoes

Although mosquitoes and flies are small, they are very harmful to the health of pigs. They can spread many infectious and parasitic diseases by biting, sucking blood or flying between feces and urine, feed and drinking water. Therefore, the prevention and control of pests and diseases in pig farms must not be ignored.

(1) Do a good job in environmental sanitation and eliminate mosquitoes and flies. The development of mosquitoes needs to go through four stages: egg, larva, pupa and adult. The first three stages of development were all carried out in water. Adults can do land activities without water. The sewers, sewage, stagnant water and septic tanks in pig farms are breeding grounds for mosquitoes. The development of flies also goes through four stages: egg, larva, pupa and adult. Adult flies like to lay eggs in wet and dirty garbage dumps, dung piles and animal carrion. In view of these situations, it is necessary to clean up the feces, garbage and weeds inside and outside the pig house in time, fill up the sewage ditch, dredge the drainage channel, beautify and green the environment around the pig house, and completely eliminate the soil where mosquitoes and flies breed.

② Use insecticides to kill mosquitoes and flies. Trichlorfon (1% aqueous solution), pyrethrum (0.2% kerosene solution), coumaphos (0.05% emulsion) and fenthion can be sprayed in the pig house, and 0.5% trichlorfon rice grains and 0.2% trichlorfon bait can be used to trap and kill flies, and they can be replaced every 3 ~ 5 days. Dichlorvos has good insecticidal effect, but its toxicity to people and animals should be paid attention to.
