Whiteflies in the Greenhouse: How to Stop Them Early

Whiteflies are extremely common greenhouse pests that can quickly spread and severely damage plants. While they may appear as small white insects, the damage they cause can be significant, especially if the problem is ignored.

How to identify whiteflies

First, they can be noticed by lifting a plant leaf – they usually hide on the underside. When the plant is disturbed, a cloud of small white insects flies up.

Main symptoms:
• yellowing leaves
• sticky residue on plants
• tiny white insects on leaves

What damage they cause

Whiteflies suck plant sap, which weakens the plants. In addition, the sticky substance they excrete promotes the growth of mold.

As a result:
• stunted growth
• reduced yield
• increased susceptibility to diseases

Most effective control methods

Sticky traps
Help to detect whitefly infestation early and reduce their numbers.

Sprays
Used for quick results when the pest population is already larger.

Long-term protection
It is important to combine several measures to stop their entire cycle.

How to avoid the problem

Regularly inspect plants, especially the undersides of leaves. Ensure good ventilation and do not overwater plants. Prevention helps avoid significant losses.
