It is also noteworthy that whiteflies are a typical drought pest. They always attack plants that are stressed. It is therefore important to ensure sufficient irrigation to avoid plants getting stressed. A greenhouse should also always be constructed in a way that whiteflies can't enter (Double door entrance, small netting size, etc.) Once they have infested a greenhouse it is almost impossible to eradicate them again. They will weaken the plants further and spread diseases.
