Seduction method

As the name suggests, it is to put some special things around the flowerpot to attract and stick xiaoheifei

1. Yellow insect stained board with special smell

Use a small stick to fix the insect stained plate and hang it at a position slightly higher than the plant. Too high or too low will affect the trapping effect

Note that when the area stained with insects reaches 60%, the stained plate shall be replaced

2. A small basin of soapy water or sugar water

Sugar water will stick to xiaoheifei, while soap contains fatty acids. After decomposition, it will become a natural wax coating. Xiaoheifei will be dehydrated to death

Dissolve the soap in water until the pH reaches 1 ~ 2 (it can be tested with pH test paper). Pay attention to dissolve it in soft water such as rainwater and cold boiled water. You can also add a small amount of sugar water to the soapy water

Isolation method

The humidity and temperature of the soil are conducive to the reproduction and growth of black insect eggs. Therefore, covering a layer of dry sand and gravel soil layer on the surface of the basin soil is also conducive to the elimination of small black flies

Of course, isolation should not only use soil, but also remember to bask in the sun in time to maintain ventilation~

Spraying method

Spray irrigation with acetamiprid diluted 3000 times or potassium permanganate diluted 1000 times. Spray once in five days. After three or four times, adults and larvae can be effectively killed

Spraying insecticides is more thorough, but there are risks. Flower friends should be careful when using them~

Self made insecticide method

Many things in life have bactericidal effects. They are not only environmentally friendly, but also have a certain effect on eliminating small black flies

1. Spray irrigation with sliced tobacco soaked in water

Nicotine in tobacco can effectively kill insects. Take several cigarettes, draw out about 20g of tobacco silk, add 500ml of clean water to soak for 24 hours, and spray the filtered liquid around the leaf surface, soil and basin bottom

2. Mosquito repellent incense

Mosquito repellent incense contains permethrin, which can effectively kill insects

Cover the flowers and plants with plastic film, put them in a small room, light mosquito repellent incense and smoke for a few minutes to effectively remove small black flies; Mosquito repellent incense can also kill larvae and eggs by directly soaking in water and watering it in the basin soil

3. Garlic soaking sprinkler irrigation

Garlic has a strong bactericidal effect. Smash a large garlic, pour half a liter of water, soak it for an hour, and spray it on the flowers and leaves to effectively kill insects
