How to Prevent a Whiteflies Infestation
It is always easier to prevent a big-scale infestation than to treat it so here are a few simple steps that you can take to prevent whiteflies from establishing a home on your indoor plants.
How to Treat a Whitefly Infestation
There is no magic solution to treating a whitefly infestation, but there are some methods that yield great results, especially if you apply them consistently. There is no need to resort to pesticides, at least not before you try some organic removal methods.
These tiny winged insects can devastate vegetable gardens and ornamental plants, but home gardeners can stop stop them without resorting to pesticides
The first sign of a budding whitefly infestation may be a host of tiny white flying insects rising from a plant when its leaves are disturbed. If left untreated, whiteflies ( Trialeurodes vaporariorum) can quickly overtake a plant, penetrating the stems and sucking out the life-giving juices within.
BEFORE YOU BEGIN
At the first indication that whiteflies are settling on plants, some growers reach for toxic chemicals to control them. Though this strategy might work, according to Planet Natural Research Center, whiteflies have developed resistance to some pesticides.
STEP 1: Vacuum infected plants
The first step in stopping whiteflies is to get them off the plant. Shooing them away or flicking them off won’t work. They’ll come right back. Instead, suck the insects up with a small handheld vacuum. Vacuuming will remove the flies and their larvae—just be sure to lift the leaves and vacuum the undersides as well.
STEP 2: Remove the most damaged leaves
Whiteflies tend to feed on one leaf and then another, sucking out all the leaf’s juices before moving on to the next one. When this happens the plant continues to send energy to the damaged leaves until they’re removed, though the damaged leaves are well past saving.
STEP 3: Clean leaves and stems with spray
A simple solution made from liquid dish soap and water will kill adult whiteflies without harming plants. Add 1 tablespoon of liquid dish soap to 1 gallon of water and mix well. Pour the solution into a plastic spray bottle and spray it on all infested plants, saturating the leaves’ upper and undersides and the stems.
STEP 4: Help plants battle pests
Keeping plants healthy by watering and fertilizing will make them strong enough to survive a whitefly infestation. A weak plant will succumb more quickly. If you find that whiteflies are a persistent problem in the garden or on your indoor plants, consider adding earthworm castings to your soil.
STEP 5: Get rid of the newcomers
Keeping a close eye on your garden will allow you to get rid of whiteflies before they can damage or kill your plants. Neem oil, an extract from the seeds of neem trees, can get rid of whiteflies without harming plants. This natural pesticide repels whiteflies and can be applied to plants at the first sight of a white-winged pest.

Which Plants Are Susceptible to Whiteflies?
Whiteflies can be found on a wide variety of plants, from ornamental flowers to warm-weather vegetables, including tomatoes, eggplant, peppers, and okra.

How to Get Rid of Whiteflies
To control whiteflies, there are various solutions and traps that you can use. The biggest tip is: start early! In the mornings and evenings, as you wander the garden or tend to your houseplants, check the back of the leaves for eggs or notice when little bugs “fly away” as you approach your plants.
1. Spray them off
If you are dealing with a small number of whiteflies on your houseplant or in a small garden, then the first thing to do is to spray or hose them off.
2. Vacuum them
If you have a few whiteflies on your houseplants, then this is a good method for you. This will not work for a garden as it is not very efficient for large amounts of plants.
3. Castile Soap Spray
Soap spray is an easy and natural method to get rid of whiteflies. It can be made at home easily and reused again and again.
4. Neem Oil
Neem Oil is a natural insecticide which causes no harm to your plants while proving effective against many types of insects.
5. Homemade Spray
The Homemade spray is simply a mixture of neem oil and soap solution. Although you can easily use either of the two mixtures separately, the combination of the two is much more potent and helps you kill off the insects much faster.
6. Sticky Traps
Whiteflies are attracted to the colour yellow. Yellow Sticky traps are designed to attract the insects towards it, and when they land on it, they get trapped in the glue, and eventually die.
7. Cut off the infested leaves
If the infestation has gone rouge and you are not sure about using any spray or other methods.
What is cabbage whitefly?
Cabbage whitefly is a sap-feeding true bug that can infest cabbage and all other types of brassica. It can be a particular problem on kale, as the insect can develop on the foliage that is destined for dinner plates.
Symptoms
White-winged insects, 1.5mm long, that fly up in clouds from the underside of brassica leaves when disturbed
Control
Cabbage whitefly can be difficult to control, particularly on allotments where there are likely to be affected plants on nearby plots that will be a source of re-infestation.
Non-pesticide control
Where possible tolerate the presence of cabbage whitefly, with the exception of Kale it does not normally affect edible parts.
Pesticide control
The immature stages are not very susceptible to insecticides and so several applications may be needed to reduce a heavy infestation. Complete eradication is neither feasible nor necessary as it is only heavy infestations that are likely to cause problems with sooty mould.
Biology
Cabbage whitefly is present on its host plants throughout the year and overwinters as adult insects.
