Browntail Moth & Emerald Ash Borer Care
Targeted, closed-loop vascular trunk injections. Save mature oak and ash trees from toxic infestations with zero chemical drift and 100% waterway safety.
The Threat of Toxic Browntail Moths & Boring Beetles
Invasive insects are destroying Maine forests and causing serious public health issues. Without professional arborist pest control, property owners face critical liabilities:
-
Severe Browntail Moth Rashes: Browntail Moth caterpillars shed microscopic, toxic hairs that float in air currents, causing painful skin rashes and severe respiratory distress for humans.
-
Rapid Emerald Ash Borer Mortality: Emerald Ash Borer (EAB) beetles infest and kill native ash trees from the inside out within three years, converting valuable shade trees into brittle falling hazards.
-
Pesticide Spray Regulations: Broadcast spraying of pesticides is heavily restricted or banned near coastal shorelines and lakeside zones, leaving shoreline trees unprotected from defoliation.
Closed-Loop Trunk Injections. Zero Chemical Drift.
At Fox Forestry, we promise to defend your trees against invasive pests without broadcasting chemical sprays. Our licensed applicators use direct vascular trunk micro-injections, circulating treatments internally within the sap stream to protect your trees safely and legally.
Protecting Canopy Vitality and Soil Biology
Browntail Moth Defense
Our early spring injections target Browntail Moth caterpillars high in oak crowns before they develop rash-inducing hairs or defoliate your woods.
Emerald Ash Borer Protection
We immunize ash trees against EAB larvae, delivering systemic protection that prevents boring beetles from chewing through vascular tissues.
Ground & Soil Safety
Trunk injections remain sealed inside the wood tissues. Soil microbes, neighboring wells, and beneficial pollinators like honeybees are never exposed.
The Science of Closed-Loop Vascular Injections
We apply insect control formulas directly into the tree's sap stream, adhering to Maine Board of Pesticides Control safety rules.
Rather than high-pressure mist spraying that drifts into wind currents and runs off into groundwater, our closed-loop injection system delivers targeted doses directly into the active vascular system. The tree's natural transpiration pulls the systemic formula upward, distributing protection to every leaf within hours.
This method is fully approved for sensitive waterfront areas, including the 250-foot Shoreland Protection Zone, where standard chemical spraying is legally prohibited.
-
Precise DBH Dosages: Injection volume calculated based on trunk Diameter at Breast Height (DBH).
-
Zero Spray Drift: Safe to apply near shoreline banks, residential decks, and organic gardens.
-
Self-Sealing Injection Ports: Small drill entry points plug naturally, preventing fungal decay entries.
Shoreland Compliance
Diagnostic Protocols & Micro-Injection Cycles
We manage the entire pest management cycle, from initial canopy audits to certified injections.
Canopy & Web Audits
An arborist checks for overwintering Browntail Moth webs or D-shaped Emerald Ash Borer exit holes.
Dosage Calibration
We calculate the exact vascular dosage based on tree species, infestation levels, and DBH measurements.
Trunk Injection
Licensed pesticide applicators drill microscopic ports near the root flare and install pressurized micro-capsules.
Annual Monitoring
We perform follow-up inspections to monitor canopy recovery, foliage density, and long-term tree health.
Forestry Decisions in Action
A closer look at real-world viewshed pruning projects across coastal Maine properties.
Tree Removal & Pruning
"A dense growth of young red spruces was crowding out the root systems of these mature, anchor Hemlocks. We hand-cleared the brush, allowing the hemlocks to establish deeper lateral root systems to hold the banking soil."
Result: Low-impact, expert removal of hazard trees encroaching on buildings or paths, deadwood removal, and visual aesthetic canopy pruning to keep your woods safe and clear.
Oceanview Pines viewshed, MDI
"Instead of topping these mature White Pines, which triggers weak, hazard sprouts, we selectively 'limbed up' the lower 35% of branches. This framed the open ocean view while preserving the upper wind-deflecting canopy."
Result: Restored panoramic views of Somes Sound, maintaining total shoreline soil hold and local town code compliance.
Shoreline Hemlock Stabilization
"A dense growth of young red spruces was crowding out the root systems of these mature, anchor Hemlocks. We hand-cleared the brush, allowing the hemlocks to establish deeper lateral root systems to hold the banking soil."
Result: Stopped active banking mud slides, framing a clear view of the bay while promoting a healthy, native ground-cover understory.

Learn MoreFrequently Asked Questions
What are the signs of a Browntail Moth infestation?
Look for tight, white silk webs wrapped around the outermost tips of oak or fruit tree branches during the winter and early spring. In the summer, look for severe leaf defoliation and feeding caterpillars.
Are tree micro-injections safe for my family and pets?
Yes. Because micro-injections are sealed directly inside the tree's vascular system, there is no chemical drift in the air or runoff on the ground. This makes it the safest option for residential properties, shorelines, and play areas.
How do systemic trunk injections protect ash trees from Emerald Ash Borer?
Trunk injections introduce a targeted formulation into the tree’s active sap flow. When the ash borer larvae feed on the wood tissues, they ingest the treatment, stopping the infestation and saving the tree.
When is the best time of year to treat trees for pests in Maine?
Trunk micro-injections are most effective in early spring (April to May) when trees are actively moving sap up to develop new leaves. Fall injections are also effective to prevent infestations for the following spring.
Can micro-injections be used near lakes and coastal shorelines in Maine?
Yes. Because micro-injections are a closed-loop system with zero chemical drift or soil runoff, they are fully approved for use in sensitive areas, including the 250-foot Shoreland Protection Zone.
