Although arborvitae are the most common host for bag worms, carports are also on the list of available sites.
In properties with high population of bag worms they will be on virtually every surface in the area including but not limited to mailboxes, fire hydrants, patio furniture, landscape lights, and of course the occasional carport.

We made a video about this tree right at a year ago and it’s time for an update.
The first picture is from June of 2025 and the second picture is from yesterday 5/27/26
While this tree may not win any beauty awards it’s clear that the treatment for Emerald Ash Borer was successful. (Not like we expected it not to work considering we treat hundreds of them per year). It could definitely use some pruning of dead wood, but it’s still here and shows some improvement despite the brutal drought we had in 2025.
It will be fun to track the progress moving forward of this tree and the others on the same site since none of them were treated previously. The next round of treatment is on schedule for May/June of 2027
Big trees. Let’s talk about them and trunk injection systems.
We want to take a quick second to showcase the top tier skills of our crew. Even with the reduced vitality of this tree, every single injection site has compartmentalized perfectly.

As a family-owned and operated business, this tree holds a treasured spot in our hearts, having grown from a seed produced by a majestic northern catalpa planted by our great uncle on our family farm in 1926.
Vanessa Kaighin-Rawson carefully harvested the seed, nurtured it through stratification, and lovingly grew it to about 5' tall before we had the privilege of installing it in the front yard of a long-time client's home. Standing approximately 15’ tall and 7” in diameter it’s on its way to becoming a statement in the neighborhood.
Nothing beats a 🌳 with a story
When it comes to deciding who you should hire to perform a trunk injection on your tree, that process should include the skillset and knowledge of the individuals performing the treatment.
We pride ourselves on doing the job correctly time after time and actively working towards the goal of a better tree.
In this video we discuss plug setting when using the Arborjet Ecologel system.
Armored scale is hot and heavy so far in 2026. All varieties of euonymus, all maple trees including Japanese maple, and all species of holly are the most common plants to find it on. However we found it on a saucer magnolia earlier this week which is uncommon for armored scale.
Minor infestations are not a real concern and can typically be handled with horticultural oil applications, however heavy infestations need more aggressive treatments using systemic insecticides.
Treated for EAB versus not treated for EAB. The difference is clear.
