Many flower friends are particularly annoyed with red spiders, especially those who raise potted monthly flowers, balconies raise potted monthly seasons, you need to often deal with red spiders, raise flowers on closed balconies or window sills, plants and flowers are particularly susceptible to infection with red spiders.
Above are the eggs and adults of the red spider (enlarged image)
1. Alleviate the reproductive rate of red spiders
The red spider is a type of mite that breeds in poorly ventilated or relatively dry environments, and the red spider is difficult to remove with an ordinary insecticide, and it will continue to recur.

If you want to alleviate the outbreak of red spiders, you can use a relatively simple method, such as in a well-ventilated environment, spraying plants with water in a clear morning (the back of the leaves should also be sprayed) to increase the ambient humidity, you can also avoid excessive reproduction of red spiders, of course, this method only has the effect of alleviating.

2. Why is it difficult to remove red spiders?
Most pesticides do not have a very good effect on red spiders, especially after red spiders become insects. If you want to remove its eggs alone, or the adults alone, it is not too difficult.
Red spiders are difficult to remove, but also because of its strong reproductive ability, fast reproduction speed, easy to develop resistance. To get rid of them, it's basically necessary to prepare two or three insecticides to remove red spiders, spraying them alternately, every three days, because they breed every three days.

Red spiders are difficult to remove because their eggs lurk under the soil and can easily erupt after the spring is warm.
3. Avoid excessive dense branches and leaves
Usually, when we maintain potted flowers, we must ensure that the ventilation between the branches and leaves of the plant is transparent, the environment should also have good ventilation, and maintain a certain air humidity, but it can reduce the breeding of diseases and insect pests.
When plants are severely infected with red spiders, small spider webs appear on the branches and leaves
When maintaining potted plants, it is not necessarily a good thing that the branches and leaves of the plant grow too densely, because dense branches and leaves are more likely to breed diseases and insect pests, including the breeding of red spiders.
When we raise flowers, we must pay attention to regularly check the state of the plant, once it is found that some small yellow spots appear on the leaves of the plant, the leaves become rough, especially some small yellow or brown spots appear on the back of the leaves, which is likely to breed red spiders.
4. Choose the right insecticide
The treatment of red spiders will generally use two or three kinds of insecticides, sprayed alternately. Avermectin can be used in the early stages, that is, in the early stage of insect eggs to achieve a certain effect.
When the outbreak of red spiders is more serious, you can use the common aviol mite, ectomolazole, pyridoxine, biphenylhydrazine, etc., choose two or three of them, spray every three days must be used alternately, do not use a single agent, otherwise the red spider will produce resistance.
These agents are generally used 1,000 times more than water, spraying the leaf back of the plant, and spraying the back of the leaf of the plant, because most of the red spiders are hidden on the back of the leaves.
Spraying insecticides should also pay attention to improving environmental ventilation, try to move plants to a better ventilated place, and cut off too many densely grown branches and leaves, and the soil surface should also be cleaned up in time.
5. Prevent the breeding of red spiders
Of course, the best way is to prevent the breeding of red spiders in advance, in addition to improving the environment, we can also regularly sprinkle some systemic insecticides in the soil, these systemic insecticides are sprinkled on the soil, regular watering, the medicinal power will be slowly absorbed by the plant, after the plant absorption, it will produce the effect of resisting pests, you can prevent the outbreak of pests, which is equivalent to giving plants a preventive injection.
Ivy infects red spiders
This systemic insecticide can use the common small white medicine, that is, "furoxamin", which is directly sprinkled on the surface of the pot soil when used, and the normal watering in the later stage can gradually penetrate into the soil and be absorbed by the plant. Once a red spider sucks up the sap of these plants, it will be poisoned.

This method can also be used to prevent pests such as aphids, red spiders, and aphid shell insects. This is also a small trick for the maintenance of potted flowers, whether it is for the care of succulents or other herbaceous flowers.
