1. Open vents and windows. Flying insects easily fly through the vents and cracks in the window. Move plants to the open air during the warmer months.
2. Acquisition of an infected plant. Buying another beautiful plant, you may not notice the lurking pests, which begin to multiply rapidly in indoor conditions, spreading to nearby crops.
3. Transfer to a new substrate. Various insects often live in the soil taken from a garden or forest. At home, parasites, finding no other food, attack the plant. Unfortunately, some purchased soils are also infected with pests.
4. Care mistakes. Overflowing, underfilling, too dry or, conversely, humid air, insufficient or excessive lighting - all this weakens the plant. The resistance of the diseased organism decreases, and insects willingly take advantage of this, attacking the flower.
As you can see, there are enough ways for aggressors to enter the closed space of the apartment. Of course, in indoor conditions, pests affect plants much less often than in open ground, but if this happens, the fight against them turns into a real difficulty.
Consider the main pests of indoor plants that infect nearby plants, moving from one plant to another. All your plants can be damaged if pest control is not started in time.
