Aphids - One of the most common cannabis pests

Awareness Prevention
Colors range between grey, white, green, yellow, black, brown, or red based on their stage of life and where you're located. If a plant is infested move it to an outside area where you can spray it to cut down the population.
They are oval-shaped and may or may not have wings. Remove leaves and buds that are heavily infected.
They will feast on any part of a plant by biting into the leaf, stem, or bud to feed on the juices inside. Insecticidal soaps
They generally live in colonies of tens or hundreds and hang out on the undersides of stems and leaves. Neem oil
Once attached, an aphid becomes fixed and is easy to spot. Spinosad
Females do not require copulating to reproduce and will produce offspring between 3 to 100 times a day. Essentria IC3
Aphids secrete large volumes of sugary liquid water known as honeydew. Honeydew drops attract sooty mold that can grow on honeydew deposits found on leaves and branches turning them black.
If you notice ants around the base of your plant, this is also a sign of an aphid infestation as the ants are attracted to the sweet honeydew and protect aphids from predators.
Broad Mites

Broad Mites

Awareness Prevention
Broad mites are very small and difficult to see even under a microscope. Neem oil
When your plant is infested with broad mites or russet mites new growth may come in twisted, blistered, and appear wet or plastic-like. Essentria IC3
If your plant is in the flowering stage, buds may turn brown and die. Insecticidal soaps
Broad mites normally hang out inside the crevices of leaves inside buds and they lay eggs inside of the plant. Mighty wash
Infestations are commonly diagnosed as overwatering, heat damage, or a nutrient deficiency. Avid
Prevention is different for broad mites since they are one of the toughest to get rid of. Forbid
When dealing with broad mites, it's recommended that you treat your plants for at least a few weeks at several times a week or even daily. Diatomaceous Earth
Repeat treatments for five more weeks after the mites are gone. Since they lay eggs inside of the plant they can come back if not completely destroyed. Heat
Fungus Gnats

Fungus Gnats

Awareness Prevention
Fungus gnat larvae are hard to see with the human eye and have transparent bodies and black heads. These gnats are common for plants that are watered too often.
They enjoy dark and moist environments and can be found at the base of your plant. Allowing the top inch of soil to dry out before watering can make them go away on their own.
Adults are grey to black in color and are very small with long legs. Blow air over the soil to dry it out making it harder for them to fly around and reproduce.
The females lay around 200 eggs per week within the first few inches of moist soil and larva can be typically be found in water runoff. Treat the top layer of soil with Neem oil.
Adult fungus gnats will generally be found swarming around the lower portion and at the base of your plant along with the larva. Apply Diatomaceous Earth to the top of the soil and around edges.
Once infested in the root system, these insects damage larger roots resulting in weak plants, slow growth, and fading foliage. Yellow sticky traps placed on the floor near plants and hanging near the top will help discourage their attack indoors.
Fungus gnats stick to the sticky flowering green and are almost impossible to remove. If you have a bad infestation, it may take weeks of good watering practices before they're gone.
The damage from these pests makes cannabis plants very vulnerable to various types of fungus.
Spider Mites

Spider Mites - Common pests that are difficult to get rid of

Awareness Prevention
Spider mites live underneath the leaves of a plant and are so tiny they look spots to the naked eye. Reduce their population by controlling the heat, this makes it harder for them to reproduce in cooler temperatures.
The leaves of your plant will be covered in yellow, orange, or white speckles which may be misdiagnosed as a nutrient deficiency. Blowing constant air over the plants combined with the cooler temps creates a cool breezy space and makes it harder for reproduction.
When spider mites attack a certain spot you will see a lot of specks near each other and the leaves may start to appear yellow or bronzed. Taking plants outside and spraying them off if possible to reduce population before starting the main treatments.
When the infestation grows you'll notice webbing that may cover foliage, flowers, and even entire buds. Spiders may be brought in by a new plant or a clone. It's important to look for new bugs or tiny spots on leaves using a microscope or magnifying glass.
Their sharp mouths pierce individual plant cells and suck out the liquid that keeps your plant alive. Keeping new plants in quarantine for at least a week and checking daily for bugs is great practice to implement.
Spider mites are visible under a strong magnifying glass and are commonly brown with two spots but can be yellow and white or red. Mighty wash.
Female spider mites become fertilized for their entire life cycle once they mate and lay on average around 100 eggs every five days (around 1 million a month). Spinosad
75% of all spider mite eggs become female. Essentria IC3
Spider mites will quickly take over a plant and can easily develop resistance to almost any method used against them. Insecticidal soaps
It's recommended to use various methods to remove them. Neem oil
Diatomaceous Earth


Awareness Prevention
Similar to spider mites, whiteflies hang out and steal nutrients from underneath cannabis leaves. Insecticidal soaps
They are easy to spot but can become hard to get rid of if ignored. Neem oil
Their eggs stick to the leaves like glue and cannot be wiped off. Spinosad
They prefer weak plants and attack them from the top down. Essentria IC3
Leaf damage from whiteflies is similar to spider mites.
The longer damage continues the more strength and energy.
