This includes introducing predatory insects like ladybugs or lacewings that feed on whiteflies, regularly monitoring and removing infested plants, practising good sanitation by removing plant debris, using sticky traps to catch adult whiteflies, and applying insecticidal soap or horticultural oil as a last resort.
2.What Are Some Natural Predators Of Whiteflies?
Ans: Some natural predators of whiteflies include ladybugs, lacewings, parasitic wasps, and spiders. These predators feed on whiteflies at various stages of their life cycle, helping to control their population naturally.
3.How Often Should You Inspect Your Plants For Signs Of Whiteflies?
Ans: We recommend inspecting your plants for signs of whiteflies regularly, ideally at least once a week. Regular monitoring allows you to detect any infestations early on and take appropriate action to prevent them from spreading. Whiteflies are small, winged insects that feed on the sap of plants, causing damage and transmitting diseases.
