What Are Whiteflies?
Whiteflies are tiny insects that often infest the leaves of basil plants.

Whiteflies feed on the sap of the plant, causing the leaves to turn yellow and wilt.
In severe cases, the whiteflies can cause the basil plant to die.
They reproduce quickly, so its important to take action as soon as you spot them on your basil plants.
Whiteflies are attracted to basil plants that are under-watered and overcrowded.
They also are drawn to plants that are stressed or weakened by other pests.
You can identify whiteflies by their white wings and the white, waxy coating that they leave on the underside of basil leaves.
They also tend to congregate near the tops of the plants.
Whiteflies can be hard to control, so its important to act quickly if you spot them.
Identifying Whiteflies on Basil Plants
Identifying whiteflies on basil plants is a key step in getting rid of them.
Whiteflies are small, white, winged insects that are often found on the underside of basil leaves.
When disturbed, they will fly into the air in a swirling cloud.
They feed on the plant sap, which causes the leaves to yellow and wilt.
Additionally, whiteflies can also cause stunted growth and premature death of the plant.
To be sure that you have whiteflies, you can inspect the undersides of the leaves closely.
If you see small, white, flying insects, then you likely have whiteflies.
Removing Affected Leaves
When it comes to getting rid of whiteflies on basil plants, the first step is to remove any affected leaves.
Whiteflies tend to congregate on the undersides of leaves, so it is important to check both sides of the leaves when inspecting for whiteflies.
If any leaves appear to have whiteflies or are otherwise damaged, it is best to remove them to prevent further damage to the plant.
Removing affected leaves can also help to reduce the amount of whiteflies in the garden, as the whiteflies will no longer have a food source.
This is an important step in the process of getting rid of whiteflies and should not be overlooked.
Knocking Off Whiteflies with Water
Getting rid of whiteflies on basil plants can be a challenge, but it doesnt have to be.
One simple and effective way to remove whiteflies from basil plants is to knock them off with a strong jet of water.
This method is particularly effective in cases where there are only a few whiteflies present on the plant.
To do this, simply use a garden hose or spray bottle to direct a strong jet of water onto the basil plant.
This will knock off any whiteflies that are present, along with any dirt or debris.
This is also a good preventative measure, as it can help to keep the plant free from new infestations of whiteflies.
Be sure to focus the spray onto the underside of the leaves, as this is where whiteflies tend to hide.
After spraying the basil plants, be sure to check the plant for any remaining whiteflies.
If any are present, you can then take additional steps to get rid of them.
Using Horticultural Oil or Insecticidal Soap
Using horticultural oil or insecticidal soap can be an effective way to get rid of whiteflies on basil without exposing them to harmful chemicals.
Horticultural oil is an oil-based product that suffocates whiteflies, while insecticidal soap can be used to disrupt whiteflies cell membranes.
Both of these products are safe to use on basil and can be effective at controlling whitefly populations.
When using horticultural oil or insecticidal soap, it is important to follow the directions on the label.
Generally, these products should be applied when the temperature is below 85 degrees Fahrenheit and when the plants are not in direct sunlight.
It is also important to make sure that all surfaces of the basil plants are coated with the product.
If the whitefly population is particularly large, it may be necessary to re-apply the product in 7-14 days.
When using horticultural oil or insecticidal soap, it is important to take all necessary precautions to avoid harming beneficial insects in the garden.
It is best to wait until dusk to apply the products, as this is when beneficial insects are least active.
If possible, it is also a good idea to cover nearby plants before applying the product.
This will help to avoid any drift that can occur when applying these products.

Additionally, you can use yellow sticky traps to help monitor the number of whiteflies in your garden.
This will help you identify areas that need to be treated to ensure that the whiteflies do not return.
