Top 10 Best Spider Mite Killers

Top 10 Best Spider Mite Killers

Spider mites are pretty dangerous insects if left uncontrolled. I know this because I've encountered them too.

When you start noticing them in your garden, you need to fight back as fast as you can. The infestation of spider mites is tough to see easily, which makes it quite challenging to get rid of them.

If they eventually take over, they can ruin everything you've worked so hard for in the past few weeks. And that's not something you'd like to experience.

But, with a spider mite killer, you can also destroy these insects like they're out to do to your beautiful plants.

However, the thing about spider mite killers is you can't just go for any type you find in the market. Some of these miticides can have adverse effects on your plants.

So, to help you make the best choice, here are the top ten spider mites killers you can use to immediately save your farm from the fierce onslaught of these tiny but palpably deadly pests! 

And, yes, they are organically safe for your plants. (See my favorite one out of the list)

But before I go into that, what really are spider mites?

What are Spider Mites

For starters who don't know what spider mites (also called red spider mites, two-spotted spider mites, or spruce spider mites) are, they're simply "spiders." 

They're also part of the arachnid family. You might have even come across these dangerous little spiders before but didn't recognize them. 

These insects are not precisely like regular spiders, as you might have thought. They are actually evil little pests out to seriously damage your lovely plants. 

I think I can describe them as one of the most annoying pests I have ever encountered in my years of farming. And without an effective solution to curb their ferocious sap-sucking instinct, they can completely ruin your whole farm if left uncontrolled.  

Spider mites usually make spider webs underneath the canopy of plants. This is to provide shelter for them as well as the eggs they'd be laying every day. 

These little pests have a short lifespan of about four weeks but reproduce rapidly. 

As a result of this high reproduction rate, spider mites can develop a strong resistance to the pesticides or miticides you might use.

Once they're able to penetrate deeply into your garden, it can sometimes become challenging to get rid of them entirely and quickly enough.

They suck on chlorophyll, which is the life support system of your plants, hindering them from photosynthesizing properly.

That is why you need a highly effective spider mite killer, like the ones I'll be recommending here for you, to save your precious farm from these dangerous little insects.

Signs You Have a Spider Mites Infestation 

Spider mites are not entirely easy to eliminate. One reason for this is that they are not easily noticed like other garden pests. They are very tiny and do not show themselves quickly. They live underneath plant leaves, which is why you may not see them until you thoroughly check your farm.

Have you noticed silky webs on your plants? It might be a tell-tale sign the tiny but dangerous spider mites are infesting you.

Spider mites, as I said earlier, usually feed on the chlorophyll of plants. 

Chlorophyll is an essential component that plants need for healthy growth and survival. And when your plants are healthy, they'll be beautifully green and robust.

But when spider mites start feasting on your plants, you might start noticing some discoloration (white and/or yellow spots begin to appear) on your leaves. 

Spider mites love warm, dry conditions and quickly reproduce in this temperate situation. A single female spider might is capable of starting a whole colony on her own. 

If you notice any spider mite on your farm, immediately get yourself a safe and organic miticide, you can use to eradicate and limit their reproduction. 

Compare-N-Save Systemic Tree and Shrub Insect Drench

This product is an excellent option if you want a quick and lasting eradication of spider mites from your farm.

This product doesn't wash off easily and can protect your plants for up to twelve months after a one-time usage. 

Unlike some other miticides that need direct contact with the pests to work fine, Compare-N-Save Systemic Tree and Shrub Insect Drench are directly absorbed into your plants through the roots for adequate protection against the pests.

To use, mix a small quantity of this miticide in water and evenly spray on the base of your plants, just close to the soil, using a pump-up sprayer. Water the bottom again, now with clean water, and you have your plants protected for long from those tiny, little beasts.

This product can, however, be too intense for some plants. So, use in small quantities to avoid poisoning your plants and don't use more than once.

If you're not entirely sure about the quantity to use, you should avoid this product completely. 

Despite this, Compare-N-Save Systemic Tree and Shrub Insect Drench can be an effective and safe miticide to use for a quick and lasting solution to spider mites on your farm.

General Hydroponics AzaMax

General Hydroponics made using natural (food grade) products rather than toxic chemicals that can ultimately damage your plants and cause your plants leaves to yellow or dry up.    

The active components of this miticide are azadirachtin A and B, and limonoids (of more than a hundred). These components work in drastically reducing the survival rates of spider mites. 

Limonoid affects the fecundity in female spider mites and also damages the eggs. The reproduction rate is of these insects is also controlled through the growth disruption and prolonged starvation of the mites. 

To use, mix with water (one tablespoon per gallon), and spraying properly on the leaves of your plants. Make sure to cover everything. 

You can regularly spray, either very early in the morning or by evening time if used outdoors. For indoor use, turn the grow lights off and apply. Lights can reverse the effect of this miticide on your precious plants. 

Your plants might grow a little thirsty from using this miticide on them. So, you might want to continually water them too wholly to avoid any risk of burning in your plants. 

You can also stop spraying your plants a few weeks to harvest. It keeps them safer and fresher for your consumption. 

General Hydroponics might cause minor irritation, so avoid direct contact with your skin. 

Something I find rather icky about this product is the unpleasantly pungent smell that it has. The manufacturers really have to do something about that smell. 

Other than this, General Hydroponics can be a perfect option for quick eradication and control of spider mites.

Central Coast Garden Products Natural

Green Cleaner, by Central Central Coast Garden Products, is another natural miticide you can use to eliminate pests and pathogens that can effectively damage your plants. 

Like General Hydroponics, Green Cleaner reduces the reproduction rate of spider mites by severely damaging both the mature spider mites as well as their laid eggs. 

Just as I mentioned earlier, spider mites reproduce at a rapid rate and might eventually develop a strong resistance to certain miticides or pesticides you might use on them. However, with Green Cleaner, any sort of resistance these tiny creatures might develop is totally eliminated.

For effective control of spider mites and/or other pests (even pathogens) on your garden, use Green Cleaner regularly until your plants have fully blossomed and are ready for harvest.

This is an excellent product for all-round protection from spider mites and other annoying plant pests. 

However, despite its effectiveness on mites, it can still be damaging to some plants. If you're growing fig, you might want to avoid using this miticide altogether.

You can, however, mix a tiny quantity in water to spray on plants. Spraying doesn't have to be all the time; you can draw a workable schedule for spraying. It is to ensure your plants don't get negatively affected by this product as a result of overuse.
