Some friends who have Petunia found that since they raised Petunia, the little black fly around the other flowers has disappeared! Look carefully, they are all glued to Petunia!
Petunia has many small hairs on its branches, and it can secrete mucus. Experienced friends must know that Petunia feels sticky. It is because of this that Petunia can stick to Heifei.
Beautiful Nanking cherry also has such an effect, similar to Petunia, beautiful Nanking cherry also has a lot of fluff on its branches and leaves. Once xiaoheifei sticks, it's hard to escape.
After Petunia and Nanking cherry tree stick xiaoheifei, you need to clean them up immediately, or for a long time, xiaoheifei's body may cause damage to the flower
However, it's not enough to rely on Petunia and Nanking cherry to control Heifei. Today, Huahua specially arranged a few unique skills for everyone, and quickly followed Huahua to learn!
Xiaoheifei has the property of tending to yellow, so we can use the yellow things around us to make the artifact of killing xiaoheifei
Cooking oil lures
1. Prepare a bowl of cooking oil and a yellow plastic plate.
2. Pour the edible oil evenly on the plastic plate, put it beside the flowerpot, and the next day you will find that there are many small black flies sticking on the plastic plate.
Detergent killing
1. Prepare a large yellow basin, pour some water, add some washing powder or detergent, and mix evenly. Put the flowerpot in a small basin, and then put it in a yellow basin.
2. The next day we will find that the water is covered with little black flies.
Yellow sticky board lures
1. If you think the above two methods are troublesome, you can buy a yellow sticky board and put it around the flowers.
2. In a day or two, the sticky board will be covered with black.
In most cases, the lure method can only kill most of xiaoheifei, but it can't be completely eradicated. To kill xiaoheifei completely, we still need some medicine.
Black chrysanthemum water
1. Prepare 500ml of clear water, spray the water with elemene insecticide ten times, mix well and shake well. Then spray on the surface of the soil, the outer wall of the flowerpot and the tray, once every 3-5 days.
2. Do not spray on plants when spraying. If you are worried that spraying on the soil will affect plants, you can only spray on the tray, but increase the dosage.
Sulphur
1. Adding a small amount of sulfur powder into the soil can prevent the little black fly from laying eggs in the soil. However, sulfur powder has a certain degree of harm, when using to wear gloves
2. If you don't have sulfur powder friends at home, you can replace them with sulfur soap. Cut off a small piece of sulfur soap and mix it with water, and pour it into the flower soil. But sulfur soap is alkaline, do not use it frequently
