Why are there small black flies all around the flowerpots of potted plants?

Do you know what a flying bug is? In fact, they are what flower friends often call Xiao Hei Fei, the scientific name "sharp-eyed mushroom mosquito", which can be understood as insects that can fly but are smaller than mosquitoes. what kind of environment do they like?

They like the dark and humid environment, usually healthy and fresh fruit will not produce small black fly, but once the fruit rotted, the small black fly everywhere.

If you put fruit next to the green apple, the water will be rotten, there will be a wet and dark environment, and this is what Xiao Hefei likes best, especially some oranges, peaches, bananas, watermelons, pears and so on, after these fruits are rotten, the place around the fruit is particularly damp.

In such a particularly humid environment, after Xiaohei mating, females can lay eggs in 24 hours and reproduce very quickly, while those eggs do not take half a month to become adults, and so on, we can see why they are prone to flooding.

If green pineapple often litters some tea grounds, coffee grounds, or people drink leftover drinks, these things are easy to breed Xiaohei Fei, although these things can be used as fertilizers, but they are not fermented and mature, so they will only be harmful to plants. Xiaohefei's greatest harm to plants is to bite off the roots, causing plants to die.

Some flower lovers buy potted green pineapple from bad vendors. If there is unripe organic fertilizer in the potted soil, it is also easy to produce Xiaohefei. Organic manure is known to be some dung or other natural substances, and it is easy to breed insects if it is not ripe. When buying green pineapple, you should also pay attention to whether the potted soil is newly added.

How to kill these obnoxious little blackflies?

Many flower lovers say that spraying is useless, that is because the method is wrong, first of all, we need to know that there is not only a small black fly above the green pineapple, but also in the soil, but also a pile of insect eggs, so we need to kill insects both on and under the soil.

(yellow sticky board is the most commonly used. Yellow will attract these mosquitoes, but they cannot be killed because there are still eggs in the soil.)

The simplest way is to use "flower protection god", adjust the medicine, irrigate the soil, and spray the plant evenly, once a week, three or four times.

Xiao Hei Fei is actually a kind of mushroom mosquito, a kind of mosquito. Do you think mosquito incense will have no effect?
