Last update on 2020-03-16 / Affiliate links / Images from Amazon Product Advertising API

Here we have a very nice natural option to go with, one made out of natural plant oils. What is really nice about this Growers Trust Spider Mite Killer is that it is biodegradable and environmentally safe, plus 100% non toxic, natural, and organic.

If you are worried about what exactly you are spraying on your weed plants, in terms of safety, then this is one of the best options you could go with.

Keep in mind that this is a foliar spray, primarily designed to be sprayed onto the leaves of your plants, but it can also be used for the soil and surrounding areas. It can be used on flowering plants and even right before harvest without affecting the taste of your weed.

It also won’t burn your plants, but should not be used during peal light hours. It’s better to use it when you have the lights off.

Pros

  • Natural and organic
  • Non toxic and biodegradable
  • Safe for plants during flowering and before harvest
  • Won’t burn plants
  • Kills on contact, more or less

Cons

  • Should not be used when lights are on

2. Garden Safe ASDFFG Neem Oil Extract Concentrate

When it comes to killing spider mites, neem oil is hands down one of the best things out there. This here is neem oil concentrate, and all you have to do is mix it with water, put it in a spray bottle, and proceed to spray your leaves, the soil surface, and surrounding areas with the solution.

Exact mixing and dilution instructions are included. What is really convenient about this Garden Safe ASDFFG Neem Oil Extract Concentrate is that it not only kills spider mites, but so much more.

This is an all in one insecticide, fungicide, and miticide, so it should take care of pretty much any kind of pest and fungus that may attack your pot plants. What’s also pretty impressive is that it can be used right up until the day of harvest with no adverse effects.

Moreover, this stuff will kill adults, larvae, and even eggs too, another big bonus indeed. Keep in mind that this product should be applied when the lights are off, as it may burn leaves otherwise.

Pros

  • Kills most insects, mites, and fungus
  • Easy to mix and spray
  • Kills adults, larvae, and eggs
  • Natural neem oil extract

Cons

  • May burn leaves

3. BioAdvanced 3-in-1 Insect, Disease and Mite Control

Last update on 2020-03-28 / Affiliate links / Images from Amazon Product Advertising API

Here we have another good option to go with, another all in once fungicide, insecticide, and miticide, one that should kill all kinds of spider mites, including adults, larvae, and the eggs too.

Simply spray it onto the leaves and soil, and it should kill spider mites, more or less on contact, as well as a wide variety of other pests and fungi too. It’s a good all in one product.

What is also impressive is that BioAdvanced 3-in-1 Insect, Disease and Mite Control is rain proof for up to 30 days, which makes this product a good choice to go with to control spider mites when growing marijuana outdoors.

That said, we would not recommend using this product indoors, as it does have quite the long list of ingredients, ingredients with many syllables that are hard to pronounce.

It does get the job done, and quite well at that, but we wouldn’t use it indoors, and we would stop using it a good couple weeks before harvest. You definitely don’t want to smoke or eat this stuff.

Pros

  • Very effective against adults, larvae, eggs
  • Easy and quick
  • Kills on contact
  • Used for mites, insects, fungus
  • Best for outdoor use

Cons

  • Plants need a couple weeks of flushing before harvest
  • May burn leaves
  • Really only for outdoor use

4. Garden Safe Brand Insecticidal Soap Insect Killer

Going back to a much more natural and organic option, here we have Garden Safe Brand Insecticidal Soap Insect Killer, which is intended for organic gardening.

This is the kind of mite and insect killer that gets used for fruits and vegetables, or in other words, for things you eat, and therefore it is also perfectly fine to use for weed plants.

Now, we would not recommend using it right before harvest, and we would do at least 7 days of flushing, but it should not alter the taste or quality of the weed. Although, that said, the packaging does claim that it can be used right up until harvest, but we personally would rather be safe than sorry.

Garden Safe Brand Insecticidal Soap Insect Killer is designed to kill spider mites, aphids, whiteflies, scale insects, and a variety of other bugs too, and it should work for adults, larvae, and eggs alike. The only issue with this stuff is that you need a lot of it and it needs to be reapplied quite often. I

t is easy to use though. Just spray it on the leaves, soil, and anywhere else spider mites have infested. This might however just be the best insecticidal soap for spier mites out there right now.

Pros

  • Super easy to use
  • Kills a variety of pests
  • Kills adults, larvae, eggs
  • Natural and organic
  • Non toxic

Cons

  • Should not use directly before harvest
  • Has to be applied liberally and often

5. Safer Brand 3 in1 Garden Spray Concentrate

Safer Brand 3 in1 Garden Spray Concentrate 32 Ounces 5462
  • Targets and kills aphids, beetles (Leaf-feeding), caterpillars (Leaf-feeding), crickets, earwigs, lace bugs, leafhoppers, mealybugs, mites, plant bugs, scale crawlers, thrips and whiteflies
  • Controls and kills powdery mildew, black spot, leaf spot, and rust
  • Organic formula ideal for use around children, pets, and wildlife
  • OMRI Listed and compliant for use in organic gardening
  • Contains potassium salts of fatty acids (12.38%) and sulfur (6.48%) as active ingredients

Last update on 2020-03-28 / Affiliate links / Images from Amazon Product Advertising API

In terms of super versatile and highly effective options to go with this Safer Brand 3 in1 Garden Spray Concentrate might just be the best spray for spider mites and more.

This stuff can kill aphids, beetles (Leaf-feeding), caterpillars (Leaf-feeding), crickets, earwigs, lace bugs, leafhoppers, mealybugs, mites, plant bugs, scale crawlers, thrips and whiteflies, and it also controls rust, leaf spot, black spot, and powdery mildew, as well as fungus too. It’s definitely a very versatile option.

This particular option is rated safe for organic gardening and can be used for fruits, veggies, and yes, your marijuana crop as well. It is an organic and non toxic formula which is nature derived, and it can be used around pets and kids, so it should be fine for both indoor and outdoor weed grow operations.

The only downsides here is that you do need to apply this stuff liberally and often, plus we would not use it directly before harvest. Beware, using too much of it may burn weed leaves, so don’t overdo it.

Pros

  • Kills a wide variety of bugs, mildew, mites, and fungus
  • Should work for all life stages of mites and insects
  • Organic, natural, non toxic
  • Very easy to use
  • Fast acting

Cons

  • May burn leaves
  • Requires flushing before harvest
  • Needs to be applied often

6. Hudson 99598 Fog Electric Atomizer Sprayer

Ok, so here we are taking a quick break from miticides to take a look at a fogger. In other words, it’s a device where you mix your miticides and pesticides, or whatever else you need, and turn it into a fog for easy application.

This is a convenient product because you can put any of the products in there which we have looked at so far. Also, if you are making your own miticide or mite killer of sorts, or are mixing a concentrated solution with water, this is a great way to go.

The Hudson 99598 Fog Electric Atomizer Sprayer might just be the best fogger for spider mites in our opinion.

Simply fill the tank, turn it on, control the output, and fog your plants. Ok, so this is probably not something you would use for a couple of indoor plants, because it’s just too much. This fogger can shoot miticide fog up to 14 feet, so it’s best used for large scale outdoor growing operations.

Pros

  • Super simple to use
  • Deep reaching
  • Sprays very far
  • Mix and fog your weed plants with your own miticide solution

Cons

  • For outdoor use only
  • Overkill for a few indoor plants

7. Solo 420 2-Liter One-Hand Pressure Sprayer

Here we have a slightly smaller handheld fogger or sprayer. Well, this is not really a fogger, but a pressurized mister, but it still works perfectly fine for spraying and misting your own miticide solution onto weed plants.

The tank is a 2 liter tank, so it should have more than enough capacity for a couple hundred plants, plus you can use ready made solutions, diluted solutions, or use it with your own miticide too.

Simply fill the tank, give the pump and few pumps, adjust the spray want to the length that works best for you, and use the trigger to spray a fine mist of doom upon all who stand in your way, in this case pesky little spider mites.

It’s a good option because it’s lightweight and handheld, it has a locking trigger to reduce fatigue, it has a telescopic wand, and it doesn’t require any kind of power source besides your arms.

We do have to say that this is not the most durable option out there, but it does get the job done just fine.

Pros

  • No power source required
  • Good capacity
  • Far and deep reaching
  • Super easy to use
  • Indoor and outdoor use

Cons

  • Not all that durable

8. Organic Neem Bliss 100% Pure Cold Pressed Neem Seed Oil

Organic Neem Bliss 100% Pure Cold Pressed Neem Seed Oil - (16 oz) High Azadirachtin Content - OMRI Listed for Organic Use
  • Neem Bliss is 100% Cold-pressed pure Organic Neem Oil, completely natural, totally free of chemicals
  • OMRI Listed (For Organic Use). Used in Organic Farming.
  • JUST ONE INGREDIENT - 100% Pure Neem Oil, natural, cold-pressed. 100% non-toxic.
  • Very effective Indoor/ Outdoor Plant Spray-High Azadirachtin content

Last update on 2020-03-28 / Affiliate links / Images from Amazon Product Advertising API

Alright, so enough with our little detour to sprayers and foggers, because here we are coming back to a well known spider mite killer, neem oil, specifically this Organic Neem Bliss 100% Pure Cold Pressed Neem Seed Oil.

We do like this stuff because it is 100% natural, organic, non toxic, and chemical free. It’s safe to use around pets and kids, it contains no chemicals, it does not kill the environment, and it’s totally safe to use on weed that is to be smoked and ingested.

Now, it is said to be organic, safe, and non-toxic, but to be on the safe side, we would still flush your weed plants for around 2 weeks before harvest, just to ensure that there are as little additives or compounds of any kind on the weed you plan on consuming or inhaling.

Simply mix this stuff with some water, put it in a fogger or sprayer, and cover the leaves, soil and surrounding area. What’s nice here is that this Organic Neem Bliss 100% Pure Cold Pressed Neem Seed Oil is fairly long lasting.

Pros

  • Organic, safe, & non toxic
  • Mix and spray
  • Kills spider mites and more
  • Indoor and outdoor use
  • Should kill all life stages of mites

Cons

  • Smells really strongly, like garlic
  • Flush plants before harvest

9. Bonide Neem Oil

Here we have another spray bottle full of neem oil, which is well known for being an effective killer of spider mites, aphids, and other such insects which may attack and kill your weed plants.

Bonide Neem Oil is 100% ready to go and can be sprayed directly onto the leaves and soil of your plants, as well as the surrounding area too, although we would not recommend getting it on walls if at all possible.

What is also convenient about this stuff is that it kills spider mites as adults, larvae, and eggs. Moreover, it keeps working for several weeks after application, so you don’t constantly have to keep applying it. Next, Bonide Neem Oil is organic, safe, and non toxic.

It can be used for indoor and outdoor purposes, and it is fine to use on fruits, veggies, and your pot plants too, although we would definitely thoroughly flush your plants for at least a week before harvest.

Pros

  • Kills spider mites and more
  • Kills mites in all 3 life stages
  • Organic and non toxic
  • Easy to use and ready to go
  • Long lasting

Cons

  • Smells bad
  • Stop using a week or two before harvest

10. SOLO 418 One-Hand Pressure Sprayer

Last update on 2020-03-28 / Affiliate links / Images from Amazon Product Advertising API

Here we actually have another convenient little handheld mister for applying fungicides, pesticides, and miticides to your weed plants. This here is the smallest one on our list today, with a tank capacity of 1 liter.

This should be more than enough to mist up to 20 or more plants, and we would recommend it for small and medium size indoor grow ops. It is of a good size, but maybe a bit too small for outdoor weed growing, especially if you have a lot of plants.

The mist does not spray that far, so it’s best for indoor use for a few plants. That said, this thing can be used with a single hand, so your other hand is free, and the fine mist it produces does spray a couple feet, so it gets pretty good and deep coverage into all nooks and crannies.

Moreover, you can create your own miticide or use a mix solution. Simply put it in the tank, give the SOLO 418 One-Hand Pressure Sprayer a few pumps, and then use the trigger to disperse a fine mist of mite killer.

Pros

  • Great for indoor use
  • Works fine for up to 20 plants, roughly
  • One handed operation
  • Super simple
  • Does not require a power source

Cons

  • Limited durability
  • Not for large scale use

Conclusion

When it comes down to it, among the best mite killing products out there, neem oil is definitely one of the best. So, as long as you get any product that contains neem oil, you should be fine. Moreover, there are also other products and solutions out there for spider mites, just beware of toxicity and flushing your weed plants properly after use.

However, the bottom line is that spider mites will kill your marijuana crop, so you need to take care of them, and the best way to go is with a great miticide and sprayer or fogger combination.
