White Flies Control Buying Guide: Everything You Need To Know


Whiteflies are tiny, flying insects that feed on the sap of plants. These pests can cause serious damage to many types of vegetation, such as vegetables, fruits, and flowers. Whiteflies can also spread plant diseases and contaminate food sources. If you think you may have a whitefly infestation on your property, then it is important to take action immediately in order to prevent further damage. To help you out with this process, here is our comprehensive guide to controlling whitefly populations.


What Are Whiteflies?


Whiteflies are small (2-3mm long), moth-like insects that belong to the Aleyrodidae family. They are called white because they often appear dusted with a powdery white coating. Whiteflies primarily feed on the sap of plants and are attracted to flowers, vegetables, trees, and several other types of vegetation.


Whitefly infestations can go unnoticed until the damage has been done and the population is established. Common signs that you may have an infestation include tiny white spots on leaves or foliage that move when disturbed, yellowing leaves, sticky honeydew substance left behind on leaves or nearby surfaces, sooty mold developing from the presence of honeydew, wilting in plants due to a lack of nutrients from sap-feeding whiteflies, and decreased plant health or vigor.


What Are The Different Types Of Whiteflies?


There are over 1,200 species of whiteflies, though the most common type is the greenhouse whitefly. Other types include the silverleaf whitefly, sweetpotato whitefly, bandedwinged whitefly, and citrus whitefly. Each species has certain characteristics that distinguish it from others.


How To Manage Whiteflies?


Whiteflies can be managed through a combination of strategies. These include using natural predators like ladybugs and lacewings to reduce populations, removing infested plants and disposing of them properly, maintaining garden hygiene by clearing away debris or dead foliage where pests may hide, applying neem oil or other insecticide sprays to affected plants after confirming an infestation has occurred, and applying sticky traps near affected plants to catch whiteflies.


How To Prevent Whitefly Infestations?


The best way to control whiteflies is to prevent them from infesting your garden in the first place. Some steps you can take include regularly cleaning away debris or dead foliage where pests may hide, planting flowers that attract natural predators like lacewings and ladybugs, introducing beneficial nematodes into the soil to reduce populations, and purchasing resistant varieties of plants if they are available. Additionally, inspect new plants before bringing them home from the nursery to make sure no whiteflies have snuck in with them.


What Insecticides Are Effective Against Whiteflies?


Insecticides such as neem oil are effective against whitefly infestations. Neem oil is a natural insecticide that contains azadirachtin, which acts as an antifeedant and insect growth regulator to stop whiteflies from feeding on plants. Other effective treatments include insecticidal soap and horticultural oils, both of which are safe for use around pets and humans when used according to label instructions.


When Should I Apply Insecticides To Control Whiteflies?


Insecticides should be applied early in the morning or late in the evening when temperatures are cooler and wind speeds are low. This will help reduce the risk of spraying yourself or other people with the product. When using neem oil, it should be applied when temperatures are below 90°F (32°C) and humidity is low. Additionally, insecticides should be applied on a regular basis to ensure whitefly populations are kept under control.


What Natural Predators Are Effective Against Whiteflies?


Several natural predators can be used to control whitefly populations in the garden. These include ladybugs, lacewings, and parasitic wasps. Ladybugs and lacewings feed on nectar, pollen, honeydews, and other plant sap sources and will help reduce whitefly populations if they are present in your garden. Parasitic wasps lay their eggs inside of whiteflies which then hatch into larvae that feed on them from the inside out. Introducing these beneficial insects into your garden is an effective way to manage whitefly infestations.


Whiteflies can be difficult to manage, but with the right combination of strategies, you can keep their populations under control. If a whitefly infestation is spotted in your garden, it’s important to act quickly by removing affected plants and applying insecticides as needed. Additionally, introducing natural predators like ladybugs and lacewings into your garden will help reduce future infestations. By following these steps, you can enjoy a healthy, pest-free garden for many years to come.
