Remove red spider on our culture

It is one of the most common pests in plantations of cannabis but we can address it in many ways.

The red spider is tiny (measuring 0.5 mm). But it is as small as harmful. It is very difficult to see, so we must be very attentive to our culture. Perhaps, before seeing the arachnid we see the traces it has left in our plant. At first we can see that the leaves or stems have a very small white dots. If the pest is more advanced the leaves lose color and you can even get to fall, when the time comes we will see the fine cobwebs behind the leaves. And if the stage of the pest is very advanced, the leaves are covered full of spider web and the plant dies.

Factors conducive to this plague

A number of causes that can favor the appearance of red spider on our culture must be taken into account. This tiny spider usually occurs when the plant is in an environment of high temperatures and very low humidity. What this bug likes is dry environment and high temperature. Also, if the plant is in a small pot and not watered far the arachnid stay at ease. If we are growing inside, plague can ruin our harvest as the temperature can be higher than outside and, separately, the plant is not in contact (as when abroad) with other insect predators that could kill it and keep safe our plantation.

How to end the plague

When, indeed, we note that our plant was infested with a plague of red spider, we have to quickly find solutions. There are home remedies that can fight these arachnids. We can divide onion skins on the floor of the crop and this food served repellent. Also, you can make tea with water and fern leaves with which to irrigate the crop. They can also be made ​​with infusions of wormwood mixed with sodium silicate which can spray the plant in autumn and spring. Another home remedy is to clean the underside of leaves with a cotton ball soaked in a mixture of alcohol and water (half water and half alcohol), this system may prove more tedious because we must clean sheets every week until the end of culture.

Permanent solutions

If we opt for products hundred percent effective, we can find on the market several solutions that will end the plague of spiders very effectively. The Spidex Phytoseiulus persimilis (against spider mite) : it is a predator for biological control red spider. It is the predator’s used against this pest and an adult is capable of pulling 5 red spiders per day or 20 eggs or larvae. Because of its great capacity for predation eliminates the pest completely.

Most Common Pests In Cannabis: Spider Mites

Spider mites are the most common pest in cannabis. These bugs live in dirty indoor and outdoor grow spaces where they feed on chlorophyll and sap, webbing all over your precious plants.

1. What Are Spider Mites?

Spider mites are common in cannabis, these small mites hide inside the buds, sucking the liquid in your plants and leaving webs all over. It’s fairly easy to eliminate them but make sure you spot them early because they can rot the buds, ruining your entire harvest really fast.

These tiny mites are related to spiders, ticks, and other small tetranychidae. They are a very common bug that attacks cannabis, seeking dark places in plants where they can lay eggs and continue to reproduce.

2. What Do Spider Mites Look Like?

These bugs are actually super tiny (around 0.5mm). They can be red or black and have 8 legs.

Because they’re so tiny, you’ll only be able to see tiny dots walking around your plant unless you have a 10x microscope available.

3. Where Are They Found?

Spider mites can be found walking all over the plant but you’ll usually find them on the underside of the fan leaves.

That’s where they lay their eggs, protecting them from the sun and other elements that may affect them.

4. What Do Spider Mites Do?

These mites feed not only on sap but also on chlorophyll, damaging the plant. Even though this can have a toll on your plant, this is not the worst they can do.

Spider mites can reproduce super fast and will use their web to protect their eggs. This means they will completely cover your plant in spider web if you don’t deal with them early.

They can even lay eggs inside the buds and when the eggs hatch, they will start eating the inside of your bud, causing bud rot.

Even though the webbing won’t kill your plant, it will be impossible to remove it if you’re in the flowering stage as it can get stuck in the flowers.

So although it doesn’t kill your plant, you will have to throw it away if you get seriously infested when flowering.

5. Spider Mites Symptoms

The symptoms you’ll see with spider mites are just signs of their presence. The first thing you see is tiny yellow or white spots, these are mites’ bite marks and they are a sign that they are feeding on your plant.

After that, you will start to see small transparent eggs stuck under the stems and leaves, this is a sign that the infestation is starting to grow.

If left untreated for around a week, you’ll see what they can do. You will start to see webbing all around your plant and you’ll be able to see the mites walking all over your plant.

6. How To Prevent Them?

Although like with other pests like Mealy bugs, there is nothing you can do to avoid them 100% other than keeping a good growing environment. Keeping your growing space clean and quarantine clones (or other plants) before bringing them in with your plants is a good way to prevent them.

Because spider mites don’t like wind, keeping a well ventilated growing room can be an effective way to prevent them also.

If you want to do everything you can to prevent them, you could slightly spray insecticides to prevent their appearance but this can affect your plant.

But the best way really is to keep your space clean, with the appropriate temperature, humidity and ventilation.

7. How To Deal With Them?

If spotted in the early stages, it can be fairly easy to remove the eggs manually or with a high-pressure sprayer to knock them down. After you remove the excess, you can apply Neem oil or a mix of alcohol and water to eliminate the rest.

Now if your plant is being taken over, it can be difficult, because they can cause bud rot and can hide inside the buds.

You will have to make the hard decision of completely eliminating them by applying harsher chemical products, with the risk of damaging your plant or applying organic and safer-to-use insecticides daily, with the risk of losing your plant to spider mites.

If your plant is severely affected, the best thing to do is throw the plant out to avoid them spreading to your other plants.

8. In Conclusion

Spider mites are the worst bugs that can attack your plant. Even though they don’t feed on the roots or something more serious like Fungus gnats, they can lay eggs inside the buds, being able to compromise the entire main cola.

Their webbing can also get stuck to the trichomes on the buds and it will be impossible to remove them completely, affecting yields and quality.

As with all other pests, we recommend checking your plants every day and take action as soon as you see any sign of bugs.
