Controlling Aphids with TreeAzin: A Healthier, Long-Term Solution for Your Trees
Aphids on Your Trees? TreeAzin® Might Be the Long-Term Fix You’ve Been Looking For
If you’ve noticed curled leaves, sticky sap on your car or patio, or black sooty mold on your trees, there’s a good chance aphids are to blame. These tiny sap-sucking insects are more than just a seasonal nuisance—they can weaken trees, distort new growth, and trigger cascading health issues over time.
While hose blasts and over-the-counter sprays might offer temporary relief, they often don’t address the root of the problem. That’s why many homeowners in Lethbridge and surrounding areas are turning to TreeAzin® trunk injections for long-term aphid control.
What Is TreeAzin?
TreeAzin is a systemic insecticide developed from neem tree seed extracts. Unlike sprays, which coat the outside of the tree, TreeAzin is injected directly into the trunk, where it’s absorbed and moved throughout the tree’s vascular system. This allows it to target pests from the inside, without exposing people, pets, or beneficial insects to surface residues.
How TreeAzin Works Against Aphids
TreeAzin doesn’t kill on contact. Instead, it disrupts aphids’ ability to feed and reproduce. Here’s what makes it effective:
Aphids that feed on treated trees stop reproducing.
Populations decline naturally as the life cycle is interrupted.
Your tree gains the upper hand and can start to recover.
This is especially useful for trees with chronic aphid problems, where repeated infestations stress the tree year after year.
When Should You Treat?
Aphids can be treated anytime during the growing season—from May right through September, as long as the tree is actively moving water. Since TreeAzin relies on sap flow to move through the tree, it’s important that the tree is hydrated and not under drought stress at the time of injection.
While earlier treatments (spring to early summer) can prevent heavy aphid populations from developing in the first place, it’s not too late to treat mid- or even late-season infestations. This is especially important for species like elms, lindens, and maples that often see late-summer surges in aphid activity.
Ideal Candidates for TreeAzin Aphid Control
We commonly use TreeAzin to treat:
Elms, especially those affected by leafcurl aphids
Birches, where dripping sap attracts ants and leads to black mold
Lindens and maples, which often suffer from aphid-related leaf stress
Ash and poplars, if aphids are causing significant decline
If your tree is in a prominent spot (like over a driveway or patio), the mess from aphids can be more than just cosmetic—it can damage paint, invite secondary pests, and create liability concerns.
Why Choose TreeAzin Over Sprays?
Here’s why many of our clients are choosing TreeAzin injections over traditional spraying:
No chemical drift—safe around children, pets, and pollinators
Long-lasting effect—one injection can offer months of control
Environmentally responsible—approved for use in municipal parks and school zones
Protects beneficial insects—like ladybugs and lacewings
It’s an excellent fit for urban yards, high-traffic areas, and customers looking for a clean, science-based solution.
What to Expect
If you’re noticing aphids, we’ll start by visiting your property for a free on-site assessment. We’ll identify the aphid species (if needed), evaluate tree health, and let you know whether TreeAzin is the best fit—or if another option makes more sense.
If you move ahead, we’ll perform the injection using our specialized equipment, and you’ll typically see a noticeable improvement within a few weeks as the aphid cycle is disrupted and tree health rebounds.
