Mosquito repellent ash can be used to kill insects. Because mosquito repellent incense contains pyrethroid, which is the main component of many insecticides, and has the function of eliminating pests and inhibiting the reproduction of pests. After the mosquito repellent incense is burned, this effective ingredient still exists, so the mosquito repellent ash can be used to kill insects.
1. Insecticidal with water: first collect the mosquito repellent ash and put it into a large cup. Then pour 50 times the volume of clear water into the cup, and mix the solution evenly. After that, put them in a watering can and spray them on the plants where there are pests, which can help kill the insects. After a period of time, you need to spray some water on the place sprayed with mosquito repellent ash water to wash away the residual materials.
2. Pavement insecticidal: first collect some mosquito repellent ash, and then spread them evenly on the surface of flower soil. This can prevent some pests from laying eggs on the surface of the flower soil. However, it should be noted that because the mosquito repellent ash is alkaline, it is not recommended to use this method to kill insects if some flowers like acid are raised, such as gardenia, rose, etc.
