The first physical method is to use water to kill insects, but we need to prepare a high-pressure water gun, or a high-pressure watering can, this method is to use a strong water flow to rinse off the red spiders and eggs on the leaves, we take the plants outdoors or to the bathroom, and then use the high-pressure water flow to rinse the front and back of the leaves, rinse twice a day, and the red spider can be eliminated for 1 week.
The second physical method is to soak the cigarette butt in water, because the cigarette contains nicotine, which is what we call nicotine, soak the cigarette butt in water for 1 night, the water will contain a large amount of nicotine, and then the water butt and soot are filtered out, and then the soaked water is poured into the watering can, sprayed once a day, sprayed once a day, sprayed 3-5 times continuously, the red spider can disappear.
The third physical method is to borrow soapy water, because soapy water has the effect of reducing the surface tension of insects, which can penetrate the protective oil film on the surface of insects, so that they lose their resistance to the outside world, which is easy to inactivate or infect, then we spray 2 times a day on the positive side of the leaf, and the red spider can be "drowned" for 1 week.
Second, chemical control methods
Chemical control method is relatively simple, that is, with the help of chemical agents spray leaves, so as to kill the red spider, here we can choose the agent is not much, such as pyridoxine, alkyne mite, gram mite, avermectin, mite danger, enemy killing, acetazole, etc., are very good drugs, buy back according to the proportion of dilution, sprinkler leaf front and back, use 3-4 times to kill the red spider.
3. Biological control methods
Biological control of red spiders is also relatively simple, that is, with the help of the natural enemies of red spiders, let the red spiders be eaten, Chinese grass moths, mite-eating ladybugs, predatory mites, etc., which we can buy online, buy back directly on the leaves or sprinkled in the pot soil, and then they can find the red spider and eat it, biological control is a continuous process, so it must be continued.
