What and How to Get Rid of Spider Mites?
Spider mites, belonging to the Acari family Tetranychidae, are famous for feeding on thousands of plant species. They usually can be found living on the underside of leaves where they produce silk webs and cause damage by puncturing plant cells that they feed on. They have sharp little mouths that pierce the plant cells and suck out all the nutrients, which for our human eyes are interpreted by visible yellow, orange, or white speckles.
Spider mites on weed is a common issue why it is prone to this when growing directly on soil. Though they are less to attack when using hydroponics, it still can happen. A major difficult thing that cannabis growers have to deal with is detection. Because they are so small, the infestation has been boosted before growers get an idea. Some uneducated growers see the tell-tale white spots but think that they just equate to nutritional deficiencies, not realizing it is a disaster waiting to happen.
Why You Should Stay Away from Spider Mites
- Spider mites have extremely fast reproduction. – One single mature female mite can produce more than a million baby mites in a couple of weeks.
- Spider mites are almost always invisible. – Sometimes after treatment, it feels like you have permanently rid of the mites, but they appear after a few days or weeks.
- They have huge appetites. Spider mites during flower stages causes a lot of problems that directly affect your yield. – These parasites can eat your entire plant in a short amount of time, and they are known to be able to kill plants overnight.
- Their webbing is hard to dispose of. – These tiny insects can cover the cannabis leaves and buds with silk-like webs that gave them their namesake. These webs can ruin your plants even after you have killed all the mites.
- Spider mites have dangerous resistance. – Spider mites can easily become immune to different pesticides and treatments. If you are unable to eradicate the entire population of spider mites, you can even make them “super mites” because of their immunity.

Some Countermeasures You Can Use to Protect Your Plants
- Essentria IC3 – This is an organic insecticide that is a mixture of horticultural oils that are safe even for humans. It is often marketed as a bed bug killer, but it is effectively used against spider mites. You only have to take note that the effect only lasts for 8 to 12 hours, so you might have to apply them daily.
- Bleach solution – You can mix one tablespoon of bleach to a pH balanced water in a spray bottle then spray to your plants and your grow area.
- Alcohol and water – You can mix together 9 parts of water to 1 part of alcohol to kill parasites and not hurt your plants.
- SM-90 – Mixing one part of SM-90 to five parts of water can kill spider mites on contact. This is also organic and even smells good.
- Neem oil – Taken from the seeds of a neem plant (Azadirachta indica) and works against spider mites upon contact. Neem oil doesn’t taste quite as nice as expected and leaves an unpleasant taste and smell to the buds.
- Insect predators – Ladybugs and predatory mites can provide some control against the numbers of your spider mite population. This is most effective against small problems but not in full infestations.
- Diatomaceous Earth – In simple terms, this is like fossil dust. You should just scatter the dust on the top of the soil and any other places in your room. This substance is harmless to animals and humans but it is incredibly sharp at the microscopic level.
Taking care of cannabis plants can come with some challenges, but there is no need to worry, as these problems come with solutions, too.
