Red spider mites, also known as short-bearded mites, are pests that specifically harm flower leaves and plants.

Five-needle pine and other trees are also susceptible to damage by red spider mites.

The body of the red spider is the size of a needle tip, dark red or purple, and can only be seen as a small red dot with the naked eye.

The orange-red transparent spherical eggs are seen. Its nymphs often gather on the back of leaves and buds of some flowers, sucking them with their mouths.

The initial symptoms of flowers are that the leaves lose their green color, the leaf edges curl upward, and then wither and fall off.

This causes the flower buds to shrink early and, in severe cases, the plant to die.

Red spider mites have 7-8 generations a year, and they start to cause damage in March and April, with serious damage in June and July.

The plants should be observed and inspected regularly. Red spider mites reproduce very quickly when the temperature is high, the humidity is high, and the ventilation is poor.

The most indispensable thing in life is fun. If you are busy and exhausted all day long without enjoying any fun, such a life is simply too boring and there is no need to do so.

Therefore, in order to relieve boredom, people will look for various hobbies in life, and growing flowers is one of them. When choosing flowers, roses are relatively popular. Because it not only has a large number of flowers and rich varieties, but also can bloom in spring, summer, autumn and winter, so flower lovers always give roses a lot of praise.

However, we have discovered that although roses are beautiful, they are afraid of the invasion of red spiders. Once red spiders appear, roses will suffer. Therefore, you might as well learn how to control them, so that roses can grow more prosperous and healthier!

1. Special flower insecticide

Using pesticides is the most correct way, but before choosing, everyone must make sure that it is used on flowers and plants. If the pesticide is used on large organisms such as cockroaches, it may have an impact on roses.

Then we should also pay attention to the fact that most pesticides are harmful to the human body. Long-term use or large-scale use is absolutely not allowed. Therefore, when using pesticides, we should also pay attention to the dosage, read the instructions carefully, and spray according to the steps correctly.

In addition, it is recommended that you wrap the roses in plastic bags before spraying the pesticides, which is very effective. It also avoids contact between the human body and the pesticides, which is a relatively safe and healthy method.

Of course, you can also place the roses in a ventilated place and spray them with insecticide, so that they will not easily enter the room and affect your family and yourself.

2. Use soapy water to treat red spider mites

If there are fewer spider mites and they are not rampant, there is another very convenient way, which is to spray some soapy water. I believe that soap is prepared in every family, so once spider mites are found, you can immediately make a bottle of soapy water to spray, quickly control the pests, and prevent the spider mites from continuing to reproduce.

When making soapy water, you should pay attention to the concentration of soap not being too high. If it is too high, it will flow into the soil, which will be corrosive to the soil, and the roots of the flowers will be damaged. And if the soapy water is too thick, it will easily cover the leaves and affect the photosynthesis of the rose.

Therefore, you just need to soak the soap in water for a while. When it becomes milky and turbid, you can use it by spraying.

3. Alcohol insecticide

In life, many people use alcohol to disinfect. So when dealing with red spider mites on roses, you can also use this principle. But the alcohol used is not professional, but the alcohol in beer, that is, using beer to spray red spider mites can play a role in disinfection and sterilization.

When using it, just pour the beer into the basin and place it under the sun. After that, you can dilute it with clean water and spray it on the roses. Spraying it every two days can effectively prevent and control red spider mites.

In fact, there are many ways to eliminate red spider mites in life, and you don’t have to use chemical methods. After all, not all flowers are outdoors, so when growing flowers indoors, you have to think carefully.
