How to kill and drive away bugs without pesticides? In fact, there are many earthworks in the countryside, and some green plants have toxins themselves. Turning them into soil pesticides is a very safe pest control method, and there are some other ways to get rid of insects. Please see my detailed introduction below.
Cigarette butts: We usually see cigarette butts, collect them, peel them off, put them in water, add a small amount of soap powder to the water, and spray them for a week, which is safe and harmless to the body. This simple way can kill some common pests, and it is also very suitable for raising flowers at home. Colorless, tasteless, non-irritating, very safe.
Ricinus communis leaves: Ricinus communis leaves have toxic and side effects and are not easy to produce insects. The soil insecticide made of castor leaves can also kill pests reasonably, and has a very good killing effect on cabbage caterpillar, mole cricket and white mud silkworm. After grinding castor leaves into fine powder, spraying them at the ratio of 65,438+0: 20 can play an insecticidal role, and castor is also a common kind in rural areas.
Sticker board: This light yellow sticker board is very popular now, and it is also a simple and easy way to prevent pesticides from being used to kill insects. It can reasonably stick to Coleoptera pests, most of which are yellow in color, which is very attractive to insects. After flying automatically, insects can stick to pests with their own stickiness, which is also very suitable for family vegetable and flower cultivation.
Melia azedarach: Melia azedarach is slightly bitter and harmful. It has been a good raw material for pest control since ancient times. Naturally, this growth habit is also widely used to make soil pesticides. The seeds of Melia azedarach droop seriously, and Melia azedarach is also called sheep dung egg tree. The leaves of Melia azedarach are collected, cut into filaments, boiled and sprayed, which can kill some key pests and diseases.
Plant ash: plant ash is not only a very good pesticide, but also an organic fertilizer with high edible value. At the seedling stage of radish and vegetables, they are particularly vulnerable to pests and diseases, so farmers will spread a layer of plant ash on small vegetable seedlings, but not too much, or they will kill them. The destructive power of plant ash to some aphids is actually remarkable.
In addition to this method, there are ways to lure pests into traps and kill them artificially under the effect of lighting.
