What Are Tree Injections?

Tree Injections are just as simple as they sound – they are shots for your trees. A solution is directly injected into the trunk so it can be transported to the rest of the tree via the vascular system. These injections are used to treat disease, eliminate invasive pests, and deliver essential nutrients to correct deficiencies.

How Do Tree Injections Work?

Tree Injections are a highly effective treatment methods for trees suffering from disease, infestation, or extreme nutrient deficiency.

Small holes are drilled into the trunk of the tree, going through the bark and other outer layers (such as the phloem and cambium) and stopping at the xylem. The xylem contains a sapwood layer that is responsible for transporting water and minerals throughout the entire tree. The appropriate formula, as determined by one of our trained technicians, is then pumped into the tree. The xylem vascular system does all the work after that, ensuring the product is distributed from the roots of the tree all the way to the canopy. Unlike other treatments, Tree Injections can provide protection for up to two years.

How Much Does It Cost for Tree Injections in Toronto?

Pricing for Tree Injections in Toronto varies based on the size of a tree requiring treatment. Local Arborist charges $10 per inch of the trunk diameter. So, for example, a mature Sugar Maple with a trunk diameter of 25 inches would cost approximately $250 for a Tree Injection service.

Common Pests and Diseases That Can Be Treated with Systemic Injections

Fire Blight

Fire Blight

Fire Blight is a bacterium that infects the tree through blossoms, leaves, or stem wounds. It is extremely detrimental to fruit producing trees (so much so that it has the capability of wiping out an entire orchard in a single growing season if not immediately treated). Tree injections, when applied in early spring, are highly effective at treating Fire Blight.

Large Poplar Borer (saperda Carcharias)

Poplar Borer

The Poplar Borer is an invasive beetle species that lays its eggs in the bark of the tree (typically aspens). When the eggs hatch, the larvae feed on the bark and sap until they begin pupation. Fully matured Poplar Borer’s finally emerge in summer months and strip trees of their leaves and new shoots. Tree injections are one of the best ways to treat for Poplar Borer.

Bronze Birch Borer

Bronze Birth Borer

Bronze Birch Borers is a common wood borer species that is detrimental to all birch species in Toronto, and throughout North America. The larvae cause the most damage to the trees by feasting on the xylem vascular layer that is beneath the bark. Tree Injections effectively kill both the larvae and adult beetles of the Bronze Birth Borer.

Birch Leaf Miner

Birch Leaf Miner

The Birch Leaf Miner is one of the most common insects that affect birch trees. Tree Injections are effective at controlling Birch Leaf Miners because of the systemic spread of insecticide through the entire tree, including the leaves that the larvae feast on.



Aphids are small, but devastating insects. These little sapsuckers feed on leaf buds and new shoots, weakening the tree and making it more susceptible to disease. Additionally, aphids secrete a sticky substance called “aphid honeydew” that attracts other pests, such as ants. Insecticides that can be directly injected provide the most comprehensive protection against aphids.

Giant Woodwasp, Banded Horntail, Or Greater Horntail (urocerus Gigas), Female

Spruce Sawfly

Spruce Sawflies get their name from the sharp dagger-like part on their head that they use to cut holes in trees and deposit eggs. They are efficient eaters and will almost entirely clean the needles off a spruce tree. Systemic insecticide applied with tree injections successfully control Spruce Sawflies.

Psylla (hemiptera: Psyllidae) Is The Dangerous Pest Of Different Plants

Cottony Psyllid

Cottony Psyllids are small, soft-bodied insects that resemble aphids. This highly invasive insect species infects both Manchurian and Black Ash trees. Insecticide treatments, such as Tree Injections, have proven to be highly effective in dealing with Cottony Psyllid.

Emerald Ash Borer

Emerald Ash Borer

If a tree becomes infested with Emerald Ash Borer, it is almost guaranteed to die. The larvae tunnel under the bark and disrupt the flow of essential nutrients throughout the tree. Your first indication of an infestation may be the leaves thinning out at the top of the tree.

How long does it take to perform a tree injection?

Tree Injection is a relatively quick process, taking around 10 – 20 minutes to complete.

Will I be able to see the injection site?

If you look closely, you may be able to see small drill holes in the base of the trunk, but these holes are very minor.

Is it safe for my children/pets to play in the yard after a tree injection is performed?

Absolutely, yes. One of the advantages of Tree Injections over other pesticide applications is that there is no risk of overspray or human exposure. The chemical goes directly into the tree and no where else, making it perfectly safe for your family to enjoy the beauty of your yard without any worries.

The tree I want to treat is next to a body of water, is that safe?

Yes. With Tree Injections, there is no risk of chemical run-off or soil leaching.

Are tree injections harmful to pollinators?

At Local Arborist, we are committed to preserving trees and the ecosystems they are part of – including beneficial insects, such as pollinators. We do not use any chemicals that contain neonicotinoids, which have been linked to declining bee populations.

Good communication and responsive to our emergency call having a large tree fall on the roof. They were very timely in their work and pricing was very reasonable. They were very precise in their work and cleaned up any after math of the removal. Highly recommend!! And would use their services again.
Claire InSync
Extremely happy with the service provided to grind a large stump. Very professional. Excellent communication and the best experience I encountered in this industry. Cleanup was also done even though I was willing to handle it myself in this case. Will use them for any future tree related work. Highly recommended.I will refer this business to others because like others I have been fooled by other company high ratings only to receive horrible service, added costs and more work for me. This one is authentic. I had bad experiences and poor follow through with too many other businesses.
Alan Nanut
Allways Service was professional, friendly and efficient. Extremely happy with their service.I got a few estimates from different companies and some of them just wanted to make a quick buck and remove an entire tree. Joel listened to our needs and budget and gave a fair estimate for what he could do to make our backyard safe.On the day of the job Joel and Shawn did an amazing job planning their work, trimming the trees and making our backyard a safe space for our daughter. I really admire what they do climbing so high up in the the trees and the skills required to do so. I highly recommend them and would use them again.They are the home tree service you didn’t know you needed until you’re dodging falling branches.
Leila Lirazan
We had two large stumps from a double oak that we needed to have cut further and ground down. The owner (Marian) explained the process clearly and gave a detailed quote, and a week later his stump grinder, Yora, did the job quickly and efficiently, despite running into some unexpected problems. Surprisingly, there was a large chuck of metal bar between the two stumps which dulled his chainsaw blade, in addition to a number of rocks, but these didn't stop Yora, and now we have clear ground and a pile of sawdust where the stumps were. He also spread some of he sawdust under our spruce trees. I would highly recommend this company.
Robert Scavone
I think Toronto's the best tree services company after I compare six companies. Super high service quality, take care of customers' feelings, with protection pad as far as possible to protect the lawn, after the completion of the cleaning, is very clean. The team was very professional, efficient and dedicated. Awesome team.If I have tree services in the future, I will not hesitate to invite their team.I highly recommend this company.
It was a positive experience in every way. Quality work at a reasonable price. I recommend them without reservation.
Tiit Leinveer
Marian and his crew were amazing to work with from start to finish.They arrived on time, worked flat out, cleaned up beautifully, and charged a very reasonable amount for the work they did on the huge tree in my backyard.I would highly recommend this company to anyone considering having their tree trimmed or removed.

Erin Mills
Very professional team. did a great job. prices are reasonable.
Keith Karunanayake
We lost part of a large maple in the big May storm with half the tree on my garage and half precariously standing. Entwined in the standing portion were phone and cable wires for many families on the street.We called the day of the storm and they answered immediately with an inspection the next day. We had to wait for a couple of weeks for the City to permit us taking down the standing portion hoping it wouldn’t fall on its own, and when they did a crew arrived promptly and carefully removed the tree without touching a single wire!The whole operation was complete in three hours, and they even swept the back yard and the roofs of two garages.The service was extremely professional, timely and it was the best quote we received. I can’t say enough about the service.
