How to treat small black flying insects on flowers?

1, prevention and drug treatment

The most direct and effective way to kill the little black flying insects in the flowerpot is to use drugs. I usually sprinkle some dinotefuran in the flowerpot in advance in spring, and many flower friends call it Xiaobaiyao. When the little black flies are born in the flowerpot, directly sprinkle a small amount of small white medicine in the flowerpot, and these small flying flies can be eliminated in a few days.

Step 2 cover the basin with sand

Of course, there are also many flower lovers who don't want to use any medicine at home for fear of polluting the environment, so they grow flowers indoors. In this case, a layer of clean river sand can be directly covered on the surface of the basin soil. blackfly likes moist humus soil, and it can effectively prevent blackfly from breeding after being covered with clean river sand.

Breeding conditions of black flying insects

1, soil

Small flying insects born in flowerpots breed in the soil. Because when planting flowers, some humus soil or other soil is used outside, and many small insect eggs are mixed inside. If the flowers are not disinfected before planting, the eggs will become bugs if they encounter suitable temperature and humidity later.

Therefore, in order to avoid insects in flowerpots, the nutrient soil used should be disinfected in advance, which can be high temperature disinfection or drug disinfection, so as to eliminate bacteria and eggs in advance and reduce the occurrence of flower diseases and insect pests in the later stage.

2. Temperature and humidity

Most eggs in the soil will turn into worms in spring, summer and autumn, because they also like warm and humid environment. After the warm weather in spring, these insects enter a high incidence period with the increase of temperature. If the soil in the flowerpot contains eggs, it will encounter moist soil after the temperature rises, providing them with good growth conditions, and a large number of small flying insects will be born in the flowerpot.
