This bug is so annoying, is there any way to get rid of it?
In fact, there are quite a few ways to get rid of the black fly. I will introduce them to you one by one.
1, yellow stick insects Speaking of stick insects, everyone should have used them. Blackfly is often yellow. When you see yellow, you will fly by yourself. Therefore, the yellow armyworm is a commonly used trapping and killing method.
Many people have done many methods of trapping and killing in order to benefit blackfly's yellowing tendency.
2. Capture and kill edible oil/laundry detergent
Pouring cooking oil into a yellow tray and placing the tray near the flowerpot can also trap and kill some blackfly.
Besides cooking oil, you can also use laundry detergent. Put the laundry detergent into the yellow basin, then block the bottom of the flowerpot with a deep tray and put the flowerpot into the yellow basin. Many blackfly will be trapped and killed in one day.
However, the effects of these methods are not very satisfactory, and they can only reduce the number of black flies and cannot be completely killed.
3. Petunia killed blackfly.
Some flower friends said Petunia could kill blackfly. What happened?
Petunia leaves have sticky things, and anyone who has raised Petunia should have found them. These sticky things can stick to the little black fly, but killing the little black fly with Petunia seems too extravagant. After all, Petunia sticks slowly. Are you sure you don't want it?
Then how can we completely eliminate the little black fly?
If we want to completely eliminate the black fly, we still have to find out the cause of the black fly. The reason why there are black flying insects is often because our basin soil is too wet and contains a lot of humus.
Then we should put an end to the little black fly completely. The blue devil thinks we should start from the source.
1, keep the basin soil relatively dry.
Keep the basin soil relatively dry and water it thoroughly.
2. Use water-soluble fertilizers in the growth process to improve the ability to resist pests and diseases.
3. Blocked the hidden escape route
Why can't Heifei be killed? Mainly because it is hidden in the soil. If you want to destroy it completely, you must end its nest, but we can't throw away these flowers, so Lan Yao suggested that you spread sand on the surface of the flowerpot.
The surface of the flowerpot is covered with sand, so Xiaofei can't fly out of the flowerpot. Of course, the little black flying outside can't get back to the flowerpot.
4. To completely kill blackfly with pesticides, it is necessary to treat both inside and outside. It is not enough to block the way out. After the flowerpot is covered with sand, it should be watered thoroughly with pyrethroid pesticides. In this way, the little black flies in the basin soil were basically eliminated.
Next, clean up the little black flies outside the flowerpot. Trapping and killing are too slow. Blue Devils like clean methods, and spray pesticides directly, such as radar spray and gunman spray (the kind that kills mosquitoes and flies). Worried that the drug concentration is too high, you can drench the leaves with clear water to see if it is ok after killing insects.
A flowerpot grows black and flies like wood with bacteria. All we have to do is pick off the fungus, and after a while, it will grow back. If there is no fungus on this piece of wood, we should take out the charcoal and dry it in the sun. Do you think it's right?
