The weather is warmer, there are more and more small black flies in the pots, and I have tried to use washing powder, chili water, and cigarette butt water to prevent and control it before, but it has an effect in a short time, and it will be born from the potting soil in the later stage, treating the symptoms but not the root cause.
Summarize the experience of flower lovers:
1. Sprinkle some difuranidin (small white medicine) in the pot, when small black fly is born in the pot, directly sprinkle a small amount of small white medicine in the pot, and these small flying insects can be eliminated in a few days.
2. Xiao Heifei likes to survive in moist soil with humus, and the potting soil is covered with sand to effectively prevent the breeding of Xiao Fei.
3. The flower soil should be sterilized. When replacing the flower soil in spring, it is best to put it in the sun for a few days, or use some carbendazim and other bactericidal and insecticidal drugs, which can reduce the occurrence of flower diseases and pests in the later stage.
4. Open windows often for ventilation and ventilation. The potting soil is too humid for a long time, and the ventilation is not good, it is easier to breed small black fly in the pot, usually to avoid the potting soil is too humid for a long time, and keep the environment well ventilated, in a dry and cool environment is not easy to attract small black fly.
