Spider Mite Treatment in Minnesota

At Birch Tree Care, we understand how pests can silently threaten the health and longevity of trees across Minnesota—and spider mites are a common, yet often overlooked, problem. These microscopic pests can cause significant damage, especially during the hot, dry summer months typical in parts of the Twin Cities region. Dry and dusty conditions further increase the risk of Spider Mite infestations.

If your trees are showing signs of discoloration, stippling, yellowing, or general decline in foliage, our Certified Arborists can help identify and treat spider mite infestations with effective, science-based solutions. We offer a range of treatment options—including chemical, biological, and manual approaches—tailored to your landscape’s specific needs.

What Are Spider Mites?

Spider Mites are tiny arachnids that feed on plant cells by piercing leaf surfaces and extracting their contents. This feeding behavior causes visible damage, including stippling and bronzing of leaves. Although they’re barely visible to the naked eye, their presence becomes obvious once damage appears.

Spider Mites thrive in warm, dry weather and can infest a wide variety of plants, including trees, shrubs, vegetables (like cucurbits, beans, and tomatoes), and other outdoor plants.

Common signs of spider mite damage include:

  • Yellow or bronze speckling on leaves (stippling)

  • Fine webbing on branches and especially the undersides of leaves

  • Visible colonies or feeding damage

  • Leaf drop or thinning foliage

  • General tree stress or a decline in overall appearance

In Minnesota, spider mites are most active from late spring through early fall, particularly during periods of drought or high heat.

They can affect both deciduous and evergreen trees, with common targets including:

  • Spruce (especially Colorado Blue Spruce)

  • Arborvitae

  • Honeylocust

  • Maples

  • Elms

  • Ash trees

Are Spider Mites Dangerous to Trees?

Yes—while a single infestation may not kill a healthy tree outright, repeated or severe infestations can lead to long-term damage. Spider Mites can stress trees, reduce vigor, and make them more susceptible to other pests and diseases. Even species that are typically resistant are not immune.

When identified early, Spider Mite problems are manageable. Without intervention, however, infestations can rapidly spread across your trees, shrubs, garden, and other surrounding vegetation.

Spider Mite Treatment and Control in Minnesota

At Birch Tree Care, we take an integrated, environmentally responsible approach to pest management. Our Spider Mite treatments are effective, science-backed, and tailored to each client’s landscape.

Because Spider Mites reproduce quickly, repeat treatments are often necessary. We use organic options—like neem oil, horticultural oil, and insecticidal soap—whenever possible.

Our Spider Mite control services include:

1. Accurate Diagnosis

Spider Mite damage can resemble symptoms of drought stress or nutrient deficiency. Our ISA Certified Arborists conduct thorough inspections to confirm the presence of mites and assess the extent of the damage.

During diagnosis, we also check for Spider Mite eggs and immature stages—such as larvae and nymphs—which are essential to identify for complete and effective management.

2. Treatment Options

Depending on the infestation severity, we may recommend:

  • Horticultural oils or insecticidal soaps: These treatments reduce feeding activity and population levels while sparing beneficial insects.

  • Miticides: For persistent outbreaks, miticides may be used. These are applied by licensed professionals to avoid unintended side effects. Some insecticides can trigger mite population spikes if not applied properly.

  • Rubbing alcohol: A diluted alcohol solution can help eliminate mites when sprayed directly onto affected areas. Test a small section first to avoid plant injury.

  • Cultural adjustments: Improving watering practices and overall tree health helps reduce stress and support recovery. Comprehensive care ensures all affected areas are addressed.

3. Preventative Care

We emphasize prevention to reduce the chance of future outbreaks. Healthy trees are more resilient to Spider Mite damage. 

Our preventative services include:

  • Deep root fertilization

  • Proper mulching and consistent watering practices

  • Seasonal inspections and monitoring

  • Regular washing of foliage to remove dust buildup

  • Monitoring outdoor plants during dry spells

  • Maintaining indoor humidity levels to prevent infestations on houseplants
