Don't let spider mites ruin your precious harvest

Spider mites are an all too common problem for cannabis growers. Whether you grow cannabis indoors or outdoors, spider mites are more common than any other type of pest. They are microscopic. They are arachnids. They will suck the life out of your beautiful plants.

The size of the spider mite is only about 4 mm. Their size makes them difficult to identify as they don't look like spiders at all and look like little dots. You will most likely find them on the underside of leaves and shoots. If you find a sea of these yellow or white dots, chances are your plants are infested with spider mites. If more than half of the leaf is covered with this mottled pattern, it must first be removed and destroyed.

Of course, the best way to keep spider mites from ruining your crops is prevention, but if these tiny critters take over your plants, there are some important steps you can take to send them back to microscopic spider hell.

These little pests quickly develop immunity to pesticides, so spraying the plant with harmful chemicals does not always work. Spider mites are members of the Acari Tetranychidae family, which has about 1,200 species. They typically live on the underside of plant leaves where they can spin a protective web and cause massive damage to plants by piercing their cells for food.

How to get rid of a pest
You can make natural repellants with garlic, citrus oil, hot peppers, and liquid algae, and use a spray bottle to spray on plants. This should help repel spider mites and prevent the infestation from spreading. If this method does not work after the fourth or fifth spraying, move on to more "heavy" artillery!

While your plants are still small, try dipping them in pyrethrin, a natural insecticide made from pyrethrum chamomile, also known as chrysanthemum. This will help repel the attacks of the spider mite. Chamomile is a stronger alternative to the above home sprays.

In our opinion, pyrethrin, the natural insecticide mentioned above, is the best choice. Neem oil, horticultural oil, cinnamaldehyde or nicotine sulfate also work well in the fight against ticks. Use these medications every five to ten days. Two or three sprays should successfully control this small infestation. Alternating the type of insecticide and/or repellant used will prevent mites from adapting and becoming resistant to these pest control methods.

Don't forget to also spray pest control products around the base of your plant's stems. Do the same for the edge of the containers. The idea is to create a kind of moat that prevents other pests from getting easy access to the plants.

Settle predatory insects in your canna garden. The two most commonly used species are Neoseiulu californicus and Mesoseiulus longpipes. About 20 carnivorous helpers per plant should do the job quickly. Before starting a batch of insects, make sure you remove and wash off any previously applied insecticides.

However, if the spider mite infestation is too extensive, predatory insects may not be up to the task. Their use is more of a pest prevention.

If you are just noticing signs of infection, lower the temperature in your grow room. The cooler the air, the slower the mites will multiply. The ideal temperature will be a little less than 20°C without compromising the well-being of the plants. And immediately apply one of the above methods until your cannabis garden is fully healed!
