What's a better way to kill rats?

1, cement to kill rats: stir-fry rice, corn, flour and other foods, add a little cooking oil, then mix in dry cement and put it in the place where rats haunt. After eating it, the cement absorbed water in the intestine and solidified, which made the mouse bloat and die. ?

2. Diesel killing rats: mix butter, engine oil and diesel oil and put them around the rat hole. When the mouse sticks to oil, it is easy to stick to dust and feel uncomfortable. They licked it with their mouths. After diesel oil enters the stomach with the digestive tract, it corrodes the stomach and kills them. ?

3. Killing rats with ammonia water: use ammonia water 1- 1.5 kg, pour it into the rat hole, and immediately block the hole. Its smell can kill mice. Poison the mouse hole with ammonia, and the mouse will not dare to enter it for a year. ?

4. Use lime to kill rats: put lime into the rat hole and then pour a small amount of water. When the hole is steaming, immediately seal the hole with wet soil. The carbon dioxide and heat generated by the reaction between quicklime and water can suffocate the mice in the hole. ?

5. Killing rats with bleaching powder: After the rat hole is found, seal the back hole, put 20g of bleaching powder into the front hole, and then pour a proper amount of water into the hole to quickly seal the hole. When bleaching powder meets water, chlorine gas will be produced, which will poison the mice in the hole. ?

6. Methamidophos is used to kill rats: 25g of methamidophos is used to mix 0.5- 1kg of rice, soybean, wheat and other grains. After 5 minutes, when the granules are filled with liquid medicine, they are scattered in fields or places where rats are infested. Because the smell of methamidophos is similar to dried radish slices, mice like to eat it, and the poisoning effect is good, but this medicine should not be placed in the places where livestock and poultry come and go at home to avoid poisoning.
