Elm Scale


Elm scale is a sap-sucking pest that can cause extensive damage to elm trees. 



Aphids are tiny, soft-bodied insects that suck the sap out of the leaves, causing them to wilt and curl.

Leaf Miner


Leaf miners are tiny insects that feed on the inside of leaves, causing them to turn brown and wilt.

Spruce Spider Mites


Spider mites are tiny pests that spin webs, and pierce and suck on the needles, causing them to turn yellow and fall off.

Spruce Weevil


Spruce weevils are beetles that feed on the buds and shoots of spruce trees, causing them to turn brown and die

We are ISA Certified Arborist and work with an Alberta Certified pesticide applicator specialized in tree care. Your trees will be treated with trunk injection of systemic insecticide. Trunk injection is a modern technology which is an effective and environmentally friendly way of treating  trees for pests. Systemic insecticide remains in the tree system for a longer time and achieves long lasting control. We do NOT spray toxic chemicals, so you can have your peace of mind that your animals, neighbours and yourself, are safe.
