Spider mites are tiny spider-like pests that invade cannabis plants and feed on their fluids, causing the plant to wilt and die. These pests are difficult to control and can quickly destroy a crop. If you suspect your plants have been infected, it’s important to act fast in order to save them.

There are a few different ways to get rid of spider mites, but the most effective method is to use a product that contains neem oil. Neem oil is a natural insecticide that will kill spider mites without harming your plants. You can find neem oil at most garden stores or online retailers.

Once you’ve purchased neem oil, mix it with water according to the manufacturer’s instructions. Then, use a spray bottle to apply the mixture to your plants, being sure to coat the undersides of the leaves where spider mites are likely to hide. Apply the mixture every two weeks until the spider mites are gone.

In addition to using neem oil, you can also try introducing beneficial predators into your grow room or greenhouse. Ladybugs and green lacewings are two examples of insects that will feed on spider mites. You can purchase these insects online or at some garden stores.

Spider mites are difficult pests to control, but with persistence and the right treatment method, you can get rid of them and save your cannabis crop.

What are spider mites?

Spider mites are tiny little creatures that are barely visible to the naked eye. They are spider-like in appearance, hence their name. These pests are notorious for infesting cannabis plants and sucking the life out of them. If left unchecked, spider mites can decimate an entire crop in a very short period of time.

There are several different species of spider mites, but the two that are most commonly found on cannabis plants are the red spider mite (Tetranychus urticae) and the green spider mite (Tetranychus cordubanensis). Both of these species are capable of causing serious damage to your plants.

Spider mites are very prolific breeders and can quickly overwhelm a plant. A single female can lay up to 20 eggs per day, and each egg can hatch into a new mite within just a few days. This rapid reproduction rate is one of the reasons why these pests are so difficult to control.

The first sign of a spider mite infestation is usually small white or yellow spots on the leaves of your plant. These spots are caused by the mites feeding on the plant tissue. As the infestation progresses, you may also see webbing on the leaves or stems. The webbing is produced by the mites as they build their nests.

If you suspect that your plant has a spider mite problem, it is important to take action immediately. These pests can spread rapidly and do serious damage to your plants if they are not controlled.

Signs of spider mite damage

The most obvious sign of spider mite damage is the presence of webbing. The webbing is produced by the spider mites to protect themselves and their eggs from predators, and to help them spread to new leaves. The webbing also protects the spider mites from insecticidal sprays, so simply spraying your plant will not get rid of them. Other signs of damage include:
-Yellow or discolored spots on the leaves
-Stippling or Bronze coloration on the leaves
-Reduced plant growth

Why are spider mites attracted to cannabis?

Spider mites are attracted to cannabis for the same reasons they are attracted to any other plant — they want to eat! This little pests are known to infest a wide variety of plants, including agricultural crops like soybeans, cotton, and potatoes. They’re especially fond of cannabis because the female mites can lay up to 300 eggs at a time, and the plants provide plenty of hiding places for them to build their webs.

What do spider mites look like?
Spider mites are small — about the size of a grain of salt — and can be difficult to see with the naked eye. They’re usually red, brown, or black, and they have eight legs. If you look closely, you may be able to see the small webs they build on the undersides of leaves.

What do spider mite bites look like?
If you think you may have spider mites, take a close look at your plants’ leaves. You may see tiny dots where the spider mites have bitten into the leaves to feed. These bites will eventually turn yellow or brown and may cause the leaves to fall off. In severe cases, an entire plant can be killed by spider mites.

How to get rid of spider mites

Spider mites are one of the most common pests that can ruin a cannabis crop. These tiny creatures are difficult to see with the naked eye, but they can cause big problems for growers. Spider mites suck the sap out of plants, which can weaken and even kill them. They can also spread diseases from plant to plant.

Physical removal

Physical removal can be done by washing your plants with water. You can also remove them by hand, but this is only practical if you have a small number of plants. This method will not get rid of all the spider mites, but it will reduce their numbers.

Another physical removal method is to use a vacuum cleaner. This will suck up the spider mites, but again, it will not get rid of all of them.

Predatory insects

Predatory insects are an effective and environmentally friendly way to get rid of spider mites. Ladybugs, lacewings and pirate bugs are all predators that will feed on spider mites. You can buy these beneficial insects online or at your local nursery.

Once you have released the predatory insects into your grow room, they will do the work of finding and eating the spider mites. It may take a few weeks for them to completely eliminate the mite population, but they will eventually get the job done.

Chemical pesticides

The most common and effective chemical pesticides for spider mite control are miticides, which are pesticides that specifically target mites. Miticides work by either killing adult mites, preventing them from reproducing, or disrupting their life cycle so that they can’t mature into adults.

There are many different brands and formulations of chemical pesticides on the market, so it’s important to read the label carefully to make sure that the product you’re using is designed for spider mite control, and that it’s safe to use on cannabis. Some of the most common and effective chemical pesticides for spider mite control include:

-Acramite 50WS Miticide
-Avid 0.15EC Miticide/Insecticide
-Envidor 2SC Miticide
-Judo 2SC Insecticide
-Kanemite 5SC Miticide
-Oberon 2SCMiticide
-Savate 0.15EC Insecticide/Miticide
-Talstar One Insecticide
-TetraSan 0.15EC Insecticide/Miticide

Remember to always follow the label directions when using any pesticide, and be sure to treat all of your plants, even if only some of them appear to be infested. spider mites can spread quickly from plant to plant, so it’s important to nip the infestation in the bud as soon as possible.

How to prevent spider mites

You can prevent spider mites by:
-Keeping your grow room clean and free of debris.
-Inspecting your plants regularly for early signs of infestation.
-Quarantining new plants before introducing them to your grow room.
-Using a fine mesh screen on vents and doors leading into your grow room.


To sum it up, spider mites are a real pain when it comes to growing cannabis. Not only are they hard to get rid of, but they can also cause serious damage to your plants. If you think you may have spider mites, it’s important to act fast and take steps to get rid of them as soon as possible.
