A very common pest for indoor plants is the spider mite.
The pest is very small and very difficult to see.
It is a small pest, black or reddish in color, that lives on the underside of leaves.
On the leaves you can see accumulations of pests - spots on the leaves from bites.
Also, when plants are affected by spider mites, they begin to stop growing, stop blooming, and a thin web appears on the plant.
The plant's leaves and flowers begin to dry out and fall off.
Spider mites do not tolerate moisture, so plants should be sprayed as a preventative measure.
Spray the flowers twice a month.
If your plants are already sick, it is worth treating them with special products. The treatment should be done three times for complete recovery.
