How to Get Rid of Spider Mites on Marijuana Plants

Getting rid of spider mites on marijuana plants starts with early detection and consistent action.
 
Here are the most effective steps to eliminate spider mites on marijuana plants:

1. Identify the Infestation Early

Before you can get rid of spider mites, you need to spot them.
 
Spider mites on marijuana plants look like tiny specks (red, yellow, or brown) on the undersides of leaves.
 
Use a magnifying glass to check for fine webbing and stippling damage.
 
Early detection makes it much easier to get rid of spider mites before they spread.
 

2. Isolate Affected Plants

Spider mites on marijuana plants spread quickly to nearby plants.
 
Move infested plants away from healthy ones to prevent the mites from moving.
 
Isolation is a critical first step when you want to get rid of spider mites on marijuana plants effectively.
 

3. Blast Them Off with Water

A strong spray of water can physically knock spider mites off marijuana plants.
 
Use a garden hose or spray bottle on a high-pressure setting.
 
Focus on the undersides of leaves where spider mites on marijuana plants love to hide.
 
Repeat this every few days to disrupt their life cycle and help get rid of spider mites.
 

4. Apply Insecticidal Soap or Neem Oil

Insecticidal soap is a gentle but effective way to get rid of spider mites on marijuana plants.
 
Mix according to the label and spray all leaf surfaces thoroughly.
 
Neem oil works too—it suffocates spider mites on marijuana plants and deters future infestations.
 
Apply in the evening to avoid leaf burn under lights.
 

5. Use a Homemade Solution

A simple mix of one teaspoon of mild dish soap per quart of water can help get rid of spider mites on marijuana plants.
 
Shake well and spray directly onto spider mites on marijuana plants.
 
Rinse after a few hours to prevent soap buildup.
 
This is a budget-friendly way to get rid of spider mites.
 

Natural Predators to Control Spider Mites on Marijuana Plants

If you prefer biological methods, natural predators can help you get rid of spider mites on marijuana plants without chemicals.
 
Here are the best beneficial insects:

1. Predatory Mites (Phytoseiulus persimilis)

These tiny mites feed exclusively on spider mites on marijuana plants.
 
Release them at the first sign of spider mites on marijuana plants.
 
They’re highly effective at wiping out an infestation when conditions are warm and humid.
 

2. Ladybugs

Ladybugs eat spider mites on marijuana plants, especially in their larval stage.
 
Release them indoors or in your grow room to help get rid of spider mites.
 
They’re a popular choice for organic growers.
 

3. Lacewing Larvae

Green lacewing larvae are voracious predators of spider mites on marijuana plants.
 
They’ll hunt down and consume spider mites on marijuana plants at every stage.
 
Order them online and release near infested leaves.
 

Chemical Treatments for Severe Spider Mite Infestations

When natural methods aren’t enough, chemical treatments can get rid of spider mites on marijuana plants quickly.
 
Use these with caution, especially during flowering.

1. Pyrethrin Sprays

Pyrethrin is derived from chrysanthemums and works fast to kill spider mites on marijuana plants.
 
It degrades quickly, so repeat applications are needed.
 
Spray thoroughly to cover all spider mites on marijuana plants.
 

2. Miticides (e.g., Spinosad, Abamectin)

Miticides are specifically formulated to get rid of spider mites on marijuana plants.
 
Follow label directions—some are for vegetative growth only.
 
Rotate miticides to prevent spider mites on marijuana plants from developing resistance.
 

3. Essential Oil Blends

Commercial blends containing rosemary, peppermint, or clove oil can get rid of spider mites on marijuana plants.
 
They’re less harsh than synthetic chemicals but still effective.
 
Always test on a small area first.
