Learn How to Get Rid of Whiteflies!

White Flies / Whitefly

White flies /whiteflys are a surprisingly tenacious marijuana pestWhite flies behave just like spider mites; they hang out underneath the leaves, stealing essential nutrients from the plant.

This results in white spots on the top side of the leaf, though most growers will notice the tiny white bugs flying around before they notice any actual leaf damage.

White flies are easily spotted with the naked eye. If you shake the plant a little, they'll fly around. They look like little white moths when they're flying around, and are tiny at around 2 millimeters long.

An infestation can get out of control if you ignore it! The eggs they lay are practically glued to the plant, so you can't wipe them off.

Proven White Fly Remedies

1.) Insecticidal soaps

Get Inseticidal soap to kill cannabis aphids - available on Amazon.com!Fatty acid salts or insecticidal soaps can be a good choice against whiteflies. They weaken the outer shell of aphids but are safe to use on your plants and they don't leave much of a residue.

With soaps, coverage is very important as it does not stay on your plant for long, so follow-up applications may be necessary. Although this is considered safe, avoid getting any on your buds!
 

2.) Neem Oil

Neem Oil will leave an unpleasant taste/smell on buds when used to treat flowering plants, so again, don't let this stuff get near your buds! There's also some evidence Neem oil may be harmful to humans so use with care! That being said, Neem oil is an all-natural remedy that is very effective against many different types of bugs and mold. You will need a mister (also called a "One-Hand Pressure Sprayer") to spray all the leaves evenly, since neem oil and water can separate easily.

3.) Spinosad

Spinosad Products (safe & organic) - Spinosad products are organic and completely harmless to pets, children, and plants. Spinosad products can be used directly to kill whiteflies on contact and should be sprayed liberally anywhere you see aphids and especially under the leaves. Although maybe not as strong against pests as some of the more harsh insecticides, it does work and it's very safe for plants, animals and humans!

Recommended: Monterey Garden Insect Spray with Spinosad

Spinosad is an organic insecticide made from the fermentation of a specific soil bacteria (actinomycete Saccharopolyspora spinosa) and kills whiteflies via ingestion or contact by effecting the insect's nervous system. Spinosad can be a good choice for organic and outdoor growers, because it is very toxic to whtieflies, but is less toxic to many beneficial insects and spiders.

Note: Most spinosad products are effective for only about 24 hours after being mixed with water, so only mix as much as you will need per application. Anything left over will be waste. 

You will need a mister (also called a "One-Hand Pressure Sprayer") to cover all the leaves evenly when spraying them with spinosad products.

4.) Essentria IC3

Essentria IC3 Insecticide is a mix of various horticultural oils that is organic and safe for humans. It is often marketed as a "bed bug killer" but it can be effective against whiteflies when the plants are treated regularly. Unfortunately it only stays effective on the plant for about 8 hours so you will want to either apply this daily or combine with other options. You will need a mister (also called a "One-Hand Pressure Sprayer") to spray all the leaves evenly.
