Homemade insecticides are not only environmentally friendly but also highly effective. Many families who grow flowers or vegetables now choose to use homemade insecticides to combat various pests. The following information, provided by the pesticide website editor, offers tips for making homemade insecticides for flower and underground pests. We hope everyone will contribute to environmental protection:

　　The following are pesticides for treating aphids on flowers:

　　1. Chop and mix 0.5 kg each of Sichuan pepper, chili pepper, pinellia, and tobacco to make raw materials. Add 0.35 kg to 0.5 kg of water per kg of raw materials and soak overnight. After filtering, the original juice is obtained. Then add 5 kg of water per kg of original juice to make the final product.

　　2. Crush 0.5 kg of ginger with 0.25 kg of water to extract the juice (remove the residue). Add 3 kg of water to every 1 kg of the original juice.

　　3. Boil 0.2 kg of Sichuan peppercorns with 2 kg of water to make 1 kg of original juice. Add 2 kg to 3 kg of water to each kg of original juice.

　　4. Laundry detergent solution: Take 2 grams of laundry detergent, add 500 grams of water and stir to make a solution, add one drop of clear oil, and spray the solution on the insects on the plants.

　　5. Soap solution: Dissolve soap in hot water at a ratio of 1:50 and spray.

　　6. Scallion liquid: Take 50 grams of scallions, mash them into a paste, add 50 grams of water, soak for 12 hours, filter, and spray with the filtrate. Spray several times a day for 3-4 consecutive days to treat aphids and other soft-bodied pests as well as powdery mildew.

　　Pesticides for controlling soil pests such as aphids, cutworms, and grubs include:

　　1. Dried arborvitae leaves, ground into a fine powder, can be mixed with seeds and applied to the soil to control grubs.

　　2. Dried castor leaves and stems, ground into powder and applied to the soil can also control grubs.

　　3. Boil 0.5 kg of Pulsatilla chinensis in 5 kg of water for 30 minutes, filter out the residue, and pour the solution over the pot after it has cooled. This can help control cutworms.

　　4. Tobacco Liquid: Tobacco contains nicotine, which has a strong contact-killing effect on aphids, spider mites, ants, etc., and also has fumigation and stomach poison effects. Take 20 grams of tobacco powder or shredded tobacco, add 500 grams of water and soak for 24 hours, then filter. Add 500 grams of 2% soapy water to the filtrate and spray it on the leaves with pests. Alternatively, you can spray the filtrate directly onto the potting soil and around the bottom of the pot without adding soapy water to kill pests in the soil.
　　5. Bitter Gourd Leaf Liquid: Crush 100-200 grams of bitter gourd leaves with water, add an equal amount of lime, stir well, and water the roots of seedlings to control cutworms.

　　6. Mothballs: Crush mothballs and place them in the potting soil to control underground pests.
