Tree Pest & Insect Control — Protect Your Trees.
From emerald ash borer to aphids and mites, the right pest treatment at the right time can save a valuable tree. We identify the culprit and treat it properly — or tell you straight if it’s too late.
Free Pest Assessment
Same-day assessment. No obligation, no surprise fees.
The wrong bug can kill a mature tree in a season or two.
Insect pests like emerald ash borer have devastated trees across the GTA. Others — aphids, scale, mites, borers — weaken trees, drop sticky honeydew, and open the door to disease.
Correct identification is everything: the treatment for borers is nothing like the treatment for aphids. We diagnose the specific pest, assess how far it’s gone, and recommend a proportionate plan.
Where a tree can be protected, we treat it. Where an infestation is too advanced, we’ll tell you honestly and handle safe removal.
Signs of a pest problem
- D-shaped exit holes (emerald ash borer)
- Sticky “honeydew” or black sooty mould on leaves
- Curling, speckled, or distorted foliage
- Sudden canopy thinning from the top down

- Visible insects, webbing, or egg masses

Questions Homeowners Ask Us
Can you save a tree with emerald ash borer?
Often, if treated before it’s too far gone. Valuable ash trees can be protected with proactive treatment; heavily infested ones may need removal.
How do I know which pest I have?
That’s our job — different pests leave different signs and need completely different treatments, so correct ID comes first.
Are the treatments safe for my family and pets?
We use targeted, professional methods appropriate to the pest and site, applied to protect people, pets, and pollinators.
When is the best time to treat?
It depends on the pest’s life cycle. We schedule treatment for when it will actually work and advise you on timing.
What if the infestation is too advanced?
We’ll tell you honestly. A badly infested tree can become a hazard, and safe removal may be the responsible option.
