Cut down their numbers!

The most important aspect of spider mite (or any marijuana pest) prevention when growing indoors is a clean and secure grow room.
Follow up in 2-3 days with something different that will also kill their eggs and any surviving adults. The adults at this point will already be more resistant to your original method so you’ll get the best results using something else for the second treatment.

If it’s possible for you to bring your plants outside or somewhere safe, you might even consider spraying off as many spider mites as you can, to get their numbers down before you start your main treatments.

Spider mites can be very quick to take over your plant, and even quicker to develop a resistance to almost any method you use to get rid of them, which is why it’s generally recommended to use multiple methods of offense against a spider mite infestation.

  • Make sure you have great airflow in your room because spider mites thrive in stagnant air. Creating lots of air movement will not only help prevent spider mites, fungus gnats and mold, but your plants love it too!
  • Spider mites like hot, dry weather. Maintaining a comfortable room temperature and a moderate amount of humidity in the grow room will help prevent or slow down a spider mite infestation.
  • If you have an air intake from outside, make sure you have some sort of filter to keep bugs from getting in
  • Sprinkle Diatomaceous Earth on top of your soil and all around your grow room – this all-natural remedy is safe for humans (we can even eat it) and works because it is very jagged on the microscopic level. Tiny spider mites get ripped apart by diatomaceous earth while plants grow through it happily

Try to keep everything clean and tidy. Not only does this help prevent bugs but it protects buds so they don’t have fibers and dust all over them!

To understand how to kill spider mites on a cannabis plant, you should understand a little about their life cycle. This will not be a one treatment job and then it’s done. To kill them all, you will need numerous treatments spaced three days apart.

Water droplets can cause burn on the leaves of your plants. Make sure your plants are not sitting under lighting when you treat them with any foliar spray.
If you are heavily into flower, then you may want to consider using the predatory bugs to kill you spider mites. Whatever method you decide to use to kill the spider mites on your cannabis plant, you will have to find out how they got in the grow room in the first place.

In some cases, you will contract spider mites during the flowering cycle. This is a difficult situation to be in, as you don’t want to spray your flowers with chemicals. Not only will it affect the flavour and smell of your cannabis, it could cause long term health problems if you smoke these chemicals.
You will see these symptoms before you see bugs. Spider mites are very hard to see with the naked eye. They also reproduce very quickly, which means if you do not act quickly, your grow room will soon be infested.
Though they will not eat your plants, they will of course, produce waste and leave them on your buds. If you have a pest problem, late in flower, no matter how you treat the infestation, it is always in your best interests to wash your buds after harvest.
The mites will then walk onto another plant and begin eating that one too. If not identified, and treated quickly, spider mites will kill your whole crop! It can go from one day everything being fine, to the next day everything covered in mites, be vigilant.
Don’t spray the plants so much that the leaves are dripping. A fine layer of the neem oil solution will do the trick. It is important to try and get every leaf, on the top, and the underside. The more area you can cover, the more successful this treatment will be. You can also lightly spray the top of your medium too.

Try using a magnifying glass on the under sides of the leaves. With enough patience, you may be able to see a small mite. These mites can be less than a millimeter in length when fully grown.
