How do I get rid of whiteflies on my 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. The dish soap solution will kill adult whiteflies. If eggs remain on the plants, they will hatch in 3 to 4 days and reinfest them.
What do whiteflies eat on plants?
Whiteflies can be found on a wide variety of plants, from ornamental flowers to warm-weather vegetables, including tomatoes, eggplant, peppers, and okra. Some species may attack sweet potatoes, plants from the cabbage family, and citrus trees. Indoors, they will feed on most common houseplants, especially those with soft, smooth leaves.
Do whiteflies attack vegetables?
Whiteflies will attack most vegetables. Listed from most to least susceptible are: Tomatoes, pepper, eggplants, cabbages, squash, and cucumbers. Whiteflies are also partial to the following vegetables: beans, corn, peas, potatoes, spinach, and radishes. Other plants like aloe vera and ferns are also sensitive to whitefly infestations.
What is the best treatment for whitefly?
Always start with blasting whiteflies (as with aphids and many other insect pests) with your watering hose or a spray bottle. This will cause them to scatter and will dislodge nymphs and eggs to some extent. Consider spraying your plants' leaves with an insecticidal soap, following the directions on the packaging.
What is a natural remedy for whiteflies?
Soap and Water Make a DIY white fly control spray by mixing 4 tablespoons of organic liquid soap with one gallon of water. You can also use a mild dishwashing liquid if you do not have organic soap. Use the solution to mist your plants thoroughly. The soapy water will kill whiteflies.
Can vinegar get rid of whiteflies?
Try making your own insecticidal soap with a recipe of one gallon water, 2 t baking soda, 2 t dish detergent, and 2 t white vinegar. Spray the pest treatment under the leaves of your plants where the white fly eggs, scale and adults reside.
How do I control whiteflies in my garden?
Reflective mulches can repel whiteflies from vegetable gardens, and yellow sticky traps can be used to monitor or, at high levels, reduce whitefly numbers. If you choose to use insecticides, insecticidal soaps or oils such as neem oil may reduce but not eliminate populations.
What keeps away whiteflies?
You can keep them off your plants by targeting their senses. Whiteflies hate the scent of thyme, lavender, peppermint, garlic, limonene, marigolds, basil, and nasturtiums. Keeping these bugs and insects from damaging your plants is a battle every gardener encounters during the growing season.
Why do whiteflies keep coming back?
Whitefly adults can fly around and lay their eggs on other nearby houseplants, especially when you start treating the infested plant. And, if you don't get rid of the adults, your whitefly infestation will just keep coming back.
Does soapy water work on whiteflies?
Small, soft-bodied insects are the best candidates for management with soapy water. Aphids, whiteflies, thrips, and mites are all good candidates for soapy water sprays.
Can hydrogen peroxide get rid of whiteflies?
You can also kill whitefly larvae with the help of a hydrogen peroxide solution. You just have to create this solution by mixing four parts of water with one part of hydrogen peroxide or around 3% solution. Once the solution is already made, pour it into the soil.
How long do white flies last?
They attach themselves to the undersides of leaves with several waxlike rods coming from their bodies, giving them the appearance of small white oval scale. The nymphs remain fixed to the plant and feed for about four weeks. After a pupa stage, the adults emerge and live for about one month.
How do you get rid of whiteflies fast?
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.

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.
Whitefly Identification
Whiteflies have pale yellow bodies and white wings. The small pests tend to collect in groups on the undersides of vegetable leaves, where you can also see their small clusters of eggs. They feed by piercing the leaves and sucking out the sap, which results in leaf damage, distorted growth or discoloration.
Physical Management
It's often possible to control outdoor whitefly populations with physical removal if you catch an infestation early. Pinch out and dispose of badly infested leaves so the flies don't spread. Rinse small colonies off the plants with a sharp spray of water.
Mulch and Traps
Reflective mulches tend to repel whiteflies from vegetable beds. A silver foil mulch, applied over the soil and around the base of the vegetable plants, helps prevent the pests from choosing your garden as a feeding ground. Make sure the vegetable plants are still getting enough water under the mulch.
Predators and Organic Controls
Ladybeetles, lacewing bugs and bigeyed bugs all feed on whiteflies, which helps keep the population in check. Avoiding chemical controls and using organic controls prevents accidentally killing these natural predators. Organic insecticidal soaps, rubbing alcohol or neem oil can kill whiteflies if you spray it directly on a colony.
What Are Whiteflies?
Whiteflies are soft-bodied, winged insects closely related to aphids and mealybugs. Despite their name, whiteflies are not a type of fly, though they do have wings and are capable of flying.
Where Are Whiteflies Found?
In USDA Zone 7 and colder, whiteflies are not able to survive winter outdoors, so their presence tends to be limited to indoor plants or greenhouse environments. However, if outdoors plants are bought from an infested greenhouse, whiteflies may become a seasonal outdoor garden pest. (Always inspect plants before bringing them home!)
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. Some species may attack sweet potatoes, plants from the cabbage family, and citrus trees. Indoors, they will feed on most common houseplants, especially those with soft, smooth leaves.
How to Identify Whiteflies
Like aphids, whiteflies use their piercing mouthparts to suck up plant juices and, in turn, produce a sticky substance known as honeydew. Honeydew left on its own can cause fungal diseases such as sooty mold to form on leaves.
Where to Find Whiteflies on Plants
Whiteflies tend to prefer to feed on new growth, so check around any newly unfurled leaves first.
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.
WHAT ARE WHITEFLIES?
Despite its name, whitefly is not a true fly, but is closely related to aphids, mealybugs, and scale. These soft-bodied winged insects feed on plant sap, causing leaf damage and a host of other problems.
IDENTIFY WHITEFLY DAMAGE
Whiteflies are similar to aphids in the kind of damage they cause. Both have piercing-sucking mouthparts that they use to extract plant sap, causing foliage damage and stunted growth. They secrete a sticky substance known as honeydew, which promotes fungal diseases such as black sooty mold.
PLANTS SUSCEPTIBLE TO WHITEFLIES
Food crops most affected include beans, brassicas, citrus, cucumber, eggplant, grape, okra, peppers, potatoes, squash, and tomatoes.
WHITEFLIES ON HOUSEPLANTS
Whiteflies will feed on most common houseplants, but prefer varieties with smooth soft leaves, which are easier to pierce with their mouthparts. Take these precautions to protect your indoor plants:
TYPES OF WHITEFLY
There are hundreds of different species, with most having a preferred food source. Until recently, greenhouse whitefly ( Trialeurodes vaporariorum ), which typically spends its entire life cycle indoors, was the most commonly found species. Other common types include bandedwinged whitefly, citrus whitefly, and giant whitefly.
Whitefly Insecticide Recipe
You can mix up a simple recipe for an insecticide spray for whiteflies right in your kitchen. First, make a base mixture with 1 tablespoon of regular dish soap (not one with added bleach or an antibacterial soap) and 1 cup of vegetable oil. Pour it into a bottle that can be sealed, and shake well to mix.
Diluting the Recipe
Now that you have your base, you can mix 1 1/2 teaspoons of it into a cup of water. Mix this in a spray bottle, and shake it well. Oil and water do not mix, so it needs to be shaken often as you are using it.
Using the Spray
Once your spray is properly diluted and mixed, you can spray your affected plants. Be sure to spray the undersides of leaves, since this is where the whiteflies tend to be. This mixture kills adult whiteflies and smothers the larvae and eggs as long as they are covered in the spray, so be sure to apply it liberally.
Alternate Recipe
Another recipe, from The Old Farmer's Almanac, recommends a mixture of five parts water, two parts rubbing alcohol and 1 tablespoon of dish soap. Mix well, and spray it on the leaves of affected plants. You might want to test this on one leaf first, in case the rubbing alcohol is damaging to the plant.
