Regarding pests, prevention is the priority. No matter how to solve it after it appears, it is a troublesome thing to deal with. There are three main points in home maintenance and pest prevention:
1. Newly bought potted plants
Don't put the newly bought plants with other plants when you go home. First, put them in an area independently for two weeks. One is to adapt plants to the temperature and humidity environment at home. On the other hand, it can also avoid infecting other plants because there are pests or eggs on new plants. After two weeks, carefully observe the leaves and back of plants to make sure there are no pests, and then put them together with other plants.
2. Potted soil
Try not to take the field soil home and use it directly. You can burn it first or steam it in a pot for a few minutes to kill bacteria, insects and eggs in the soil with high temperature, or you can buy the finished soil of the brand directly.
3. Water and fertilize
When watering and fertilizing, do not use water and fertilizers that are not fully fermented, such as unfermented peel and rice washing water, because these unfermented organic substances will slowly ferment in the flowerpot after entering the flowerpot, and the smell emitted during fermentation will attract various insects.
How to solve pests
First of all, when pests are found in flowerpots, the first thing to do is to isolate them, especially the highly contagious pests such as red spiders and whiteflies. Be sure to keep plants with pests away from other plants to avoid large-scale spread.
Secondly, there are many similar topics in the circle of friends about how to solve pests, such as spraying pesticides at home and smoking with mosquito-repellent incense and pepper water. So are these methods reliable? First of all, you can be sure that these methods are reliable for some solid plants, but they are definitely not applicable for some plants with high environmental requirements. Maybe you spray all the flowers with pesticides at home, because the application purpose of these pesticides is not to kill insects in plants, and some chemicals in them are also harmful to plants, so don't use these methods for those expensive plants that are difficult to raise at home.
1. blackfly, whitefly, aphid, fruit fly, liriomyza sativae and thrips.
The main feature of this insect is that it can basically fly. Unless sprayed on insects, it is not easy to kill. For example, aphids and whiteflies are particularly fertile and easy to spread on a large scale.
Solution:
1, using yellow board to trap and kill, and using the yellowing characteristics of insects, hanging yellow board to induce adhesion is also a popular way in recent years. Many greenhouses also use this method, which is characterized by quick effect, low cost and no pollution, and is more suitable for indoor flower lovers. Because it is not an insecticidal pesticide, it will not pollute the indoor air and will not cause harm to the human body. Generally, it can be purchased through Taobao or other channels.

2. Insecticides can be used, such as fipronil suspension, thiamethoxam water dispersible granules, buprofezin wettable powder and imidacloprid water dispersible granules. Pesticides must be carried out outdoors, because these chemicals will have some adverse effects on the human body, especially on the elderly and children at home.
Second, red spiders and scale insects
The environment where spider pests occur is generally high temperature and low humidity, so try to avoid high temperature and high dry environment in the conservation environment. Once the spider pest occurs, it will do great harm to plants. At first, the spider's activity range is mainly under the leaves, so it is often flooded when it is found, and it is more likely to appear on Chinese rose and gardenia.
Red spider rose
Solution:
1, after repeated washing, it is found that there are red spiders or scale insects in the cultivated plants. Immediately, the whole plant, especially the back of the leaves, is washed repeatedly with tap water for several days until it disappears completely. This method is particularly effective for small plants, and there is no chemical pollution, which is more suitable for friends who grow flowers indoors. Scale insects can also use 1: 1.
2. Insecticides are generally selected as ethiconazole, flufenuron, spirodiclofen, cypermethrin, pyridaben, etc. Spraying for 2-3 times can kill it. Like other pesticides, it should be sprayed outdoors to avoid indoor pesticide pollution.
