How to Get Rid of Spider Mites on Arborvitae

The first step to getting rid of spider mites on arborvitae is confirming they’re the problem.
 
Spider mites are nearly invisible to the naked eye, but you can spot their telltale signs.
 
Here’s how to get rid of spider mites on arborvitae starting with proper identification and immediate action.
 

1. Identify Spider Mites on Arborvitae Early

Look for stippling on needles, tiny yellow or bronze spots, and fine silk webbing between branches.
 
To confirm, hold a white piece of paper under a branch and tap it, then look for tiny moving specks.
 
Early identification makes it much easier to get rid of spider mites on arborvitae before they multiply.
 

2. Blast Them Off with Water

One of the simplest ways to get rid of spider mites on arborvitae is a strong jet of water from a garden hose.
 
Aim the spray at the undersides of branches where spider mites congregate, and repeat every few days.
 
This knocks off adult mites, eggs, and webs, reducing the population without any chemicals.
 
It’s a crucial first step in how to get rid of spider mites on arborvitae naturally.

3. Apply Neem Oil or Insecticidal Soap

After hosing down your arborvitae, treat with neem oil or insecticidal soap to kill remaining spider mites.
 
Mix according to label directions and spray thoroughly, especially on branch undersides.
 
These products are effective and safe for beneficial insects when used correctly.
 
Reapply weekly until you no longer see signs of spider mites on arborvitae.
 

Natural Ways to Get Rid of Spider Mites on Arborvitae

If you prefer organic methods, there are several natural ways to get rid of spider mites on arborvitae.
 
These approaches work well for light to moderate infestations.
 

1. Introduce Predatory Insects

Release ladybugs or predatory mites onto your arborvitae to naturally control spider mites.
 
These beneficial bugs feed on spider mite eggs and adults, helping get rid of spider mites on arborvitae without sprays.
 
Order from a garden supplier and release in the evening when temperatures are cooler.
 

2. Use Horticultural Oil

Horticultural oil smothers spider mites and their eggs, making it a great option to get rid of spider mites on arborvitae.
 
Apply when temperatures are below 85°F to avoid leaf burn, and cover all surfaces.
 
Repeat every 7–10 days for several weeks to break the life cycle.
 

3. Boost Your Arborvitae’s Health

Healthy arborvitae are more resistant to spider mite damage.
 
Water deeply during dry spells, mulch around the base, and avoid over-fertilizing with nitrogen.
 
Stress from drought makes spider mites on arborvitae worse, so keep your plants hydrated.
 

Chemical Options for Severe Spider Mite Infestations on Arborvitae

If natural methods aren’t enough to get rid of spider mites on arborvitae, chemical miticides may be necessary.
 
Use these as a last resort and follow safety guidelines carefully.
 

1. Choose a Miticide Specifically for Spider Mites on Arborvitae

Look for products containing active ingredients like bifenthrin, abamectin, or spiromesifen.
 
Always read the label to ensure it’s safe for arborvitae and follow application instructions.
 
Spray thoroughly to cover all foliage, especially the inner canopy where spider mites hide.
 

2. Time Your Application Correctly

Apply miticides in early morning or late evening to avoid harming bees and other pollinators.
 
Repeat applications may be needed every 7–14 days, as spider mites reproduce rapidly.
 
Rotate between different miticides to prevent resistance from developing.
 

3. Combine with Cultural Controls

Even when using chemicals, continue water sprays and pruning of heavily infested branches.
 
This integrated approach is the most reliable way to completely get rid of spider mites on arborvitae.
