The whitefly is one of the most destructive pests for growing tomatoes, cucumbers, and eggplants in covered greenhouses. It is quite difficult to eradicate due to its larvae hiding under the leaves and its ability to rapidly develop resistance to insecticides. To solve this problem, merely spraying pesticides is not enough; isolation, correct timing, and a detailed disinfection process must be applied together.
Flea shampoos produced for cats and dogs show a surprisingly high level of effectiveness in combating whiteflies. The animal shampoo is diluted with water and thoroughly applied, especially to the undersides of the leaves. Exactly three days after the first application, a second spraying is necessary to destroy the larvae hatching from new eggs, which prevents the pest population from rebounding.
After the harvest season ends, completely disinfecting the greenhouse is of great importance to prevent the pest from overwintering. All plant debris must be removed from the greenhouse and burned, the greenhouse structure must be washed with water, and fumigation must be performed using tobacco tablets that emit nicotine smoke. Ensuring continuous isolation and using yellow sticky traps guarantee the long-term success of this control effort.

常见问题
- 1. Q: Is flea shampoo safe for all types of vegetables in greenhouses?
- A: It is suitable for crops with a long maturation period; however, for vegetables to be harvested within 1-2 days, it is safer to use mechanical methods or traps.
- 2. Q: Why must the second spraying be done exactly three days after the first application?
- A: The three-day period is when new larvae hatch from the eggs unaffected by the first spraying; spraying at this stage ensures the eradication of the population.
- 3. Q: What are the most common mistakes made during the control process?
- A: Spraying only the tops of the leaves, delaying the second application, and failing to isolate the greenhouse entrance to allow the pest to return are the most common mistakes.
