Signs of Tree Insect and Disease Problems in Toronto

A thriving landscape requires vigilance. When trees show signs of distress, it's often the result of hidden pests or diseases. Al Miley & Associates understands how critical it is to identify these issues early.


Common indicators that something is amiss include:

  • Visible Damage to Tree Bark:

    Cracks, peeling, or holes may suggest an insect infestation, such as spider mites or Japanese beetles, compromising the tree’s integrity.

  • Discoloration of Leaves and Foliage

    If you notice leaves yellowing or browning prematurely, this could signal the presence of tree diseases that are affecting the plant's health.

  • Abnormalities on Branches and Twigs:

    Look out for swollen branches or irregular growth patterns. These can indicate that tree pests are present and feeding beneath the surface.

  • Falling or Deformed Fruit:

    A reduction in fruit size or deformities may point to underlying infections or insect infestations that target plants at a vital stage.

  • Unusual Activity Around the Trunk:

    Sawdust piles or frass at the base of the trunk are telltale signs of wood-boring insects, which can cause serious damage if not treated promptly.

Early detection is crucial. We recommend a thorough inspection by our team to diagnose these issues accurately. By addressing problems early, you can protect the health and longevity of your trees.

We Control Pest Populations to Protect Your Landscape

Small pests can wreak havoc on your landscape, quietly damaging your property. We focus on managing these threats effectively, ensuring that your landscape plants and trees remain in good health.

How Early Spring Treatments Can Prevent Tree Infestations

Spring is a critical time for managing tree pests and protecting your landscape. As the weather warms, insects like the emerald ash borer become more active, making early intervention essential.

Applying horticultural oil to tree bark and branches at the right time can effectively suffocate overwintering pests before they cause serious damage. This treatment helps safeguard the health of your trees and shrubs, reducing the likelihood of infestations later in the season. By focusing on early spring, we can address potential threats to your trees before they escalate, ensuring your landscape remains vibrant and healthy.

Benefits of Horticultural Oil for Healthy Tree Leaves and Bark


Healthy tree leaves and bark are essential for maintaining robust trees and shrubs. Horticultural oil is a powerful tool in our disease management arsenal, offering a natural way to control pests like spider mites and scale insects. By coating the tree’s bark and leaves, this oil suffocates overwintering pests and prevents infestations in the spring.

  • Smothers tree pests, such as spider mites and scale, before they become a problem.

  • Safe for trees and shrubs, targeting pests without harming beneficial insects.

  • Effective against pests on tree trunks and branches, offering full coverage.

  • Helps prevent emerald ash borer and other insect infestations, protecting your property.

Effective Disease Management for Healthy Trees and Shrubs


Healthy trees and shrubs are the backbone of a thriving landscape, yet they can be vulnerable to diseases that slowly degrade their vitality. These issues often start unnoticed, with small signs like discolored leaves or abnormal growth patterns. Our team at Al Miley & Associates understands that timely intervention is the most effective way to protect your landscape from serious damage.

For instance, Ash trees, particularly susceptible to infestations like the Emerald Ash Borer, require precise monitoring and early treatment to avoid becoming diseased trees that may eventually need removal. By addressing these problems at the root—literally and figuratively — we ensure your trees and shrubs continue to contribute to the beauty and health of your property.

We Treat All Species: Oak, Birch, and Beyond


We treat a wide variety of tree species, ensuring that each one receives the specific care it needs. From the majestic oak to the delicate birch, our expertise covers it all.


  • Oak Trees:

    Recognizable by their strong, thick trunks, oaks can be prone to pests like the oak leaf miner, which can cause significant leaf damage if not treated promptly.

  • Birch Trees:

    Known for their distinctive white bark, birch trees are often affected by the bronze birch borer, a pest that targets weakened trees, leading to potential dieback if left unchecked.

  • Maple Trees:

    Maple trees, with their dense foliage, can attract pests like the maple scale, which attaches to the branches and feeds on the sap, weakening the tree over time.

  • Ash Trees:

    Particularly susceptible to the emerald ash borer, which can devastate an ash tree if not treated early. It's crucial to monitor the trunk and bark for signs of infestation.
