Evergreens
The spruce is going bare from the bottom
Needle cast, almost always, and it moves upward a whorl a year. The needles that are already gone do not come back, which is why the timing of the first spray matters more than the product in it.
Tree Pest & Disease Treatment in Omaha
Bagworm, borers, beetles, aphids, needle cast, scab and rust — diagnosed by an ISA Certified Arborist and treated on the window that actually works.

Three things people notice from the driveway
Deciduous
Something is eating the leaves to lace
Japanese beetle in July, bagworm on anything with a needle, and both of them are far cheaper to stop in the two weeks they are vulnerable than in the month they are obvious.
Everything under it
The patio is sticky and the car is spotted
Aphid honeydew, not sap. The tree is usually fine. The black film that grows on the honeydew is the part people actually want gone.
Send a photo of the damage. An arborist will tell you what it is before anybody drives out.
A year of treatment windows, drawn to length
Annual programOne year, March through February
Dormant oil and scale timing
March
Before bud break, while overwintering insects are exposed and nothing is in leaf to be damaged.
Needle cast and apple scab sprays
April to May
Fungal sprays only work as a shield on new growth. Applied after the tissue is infected, they do nothing at all.
Bagworm hatch
Late May to mid June
A two-week window while the larvae are small and feeding openly. After that they are sealed in a bag no spray reaches.
Japanese beetle emergence
Late June to August
Adults arrive in force and feed for weeks. Treatment is about protecting the canopy through the flight, not eliminating the population.
Borer and aphid follow-up
August to September
Late-season checks on treated trees and the last window for anything systemic to move before dormancy.
Dormant season
October to February
Nothing gets sprayed. This is when the next year is planned and when structural pruning happens instead.
Windows shift a week or two with the season. Crews work to soil temperature and degree days rather than to dates on a wall calendar.
Six treatments, each on its own schedule
Plant health care
Spruce
Needle Cast Treatment
Two look-alike fungi hit spruce in this metro and they are not treated on the same schedule, so we confirm which one before anything is applied.

Timing-critical
Bagworm Control
A two-week hatch window decides the whole season. Handled then it is routine; handled in August it is hand-picking bags off an evergreen.

July
Japanese Beetle Control
Skeletonized leaves on linden, birch and roses from late June. Protecting the canopy through the flight is the realistic goal.

Systemic
Borer Control
Beyond emerald ash borer: bronze birch, flatheaded appletree and clearwing borers all work under the bark where sprays cannot follow.

Crabapple
Apple Scab & Rust
Crabapples dropping half their leaves by July. Ugly, rarely fatal, and entirely a question of next spring's spray timing.

Honeydew
Aphid Control
The sticky patio problem. Treated for the mess and the sooty mold more often than for the health of the tree itself.

One visit can cover several of these on the same trees.
How it gets named
Four questions that identify most of it
Species first
Half of the calls we get are already answered by what the tree is. Spruce and crabapple each have a short list of likely culprits.
Where the damage starts
Bottom-up on an evergreen, top-down on a shade tree and inside-out on a canopy are three different families of problem.
Whether it is spreading
A single branch is often mechanical or root damage. A pattern across the whole tree is pest or disease.
What the neighbors have
Most of what we treat runs through a neighborhood rather than through one yard, so the street is part of the diagnosis.
Three ways to handle a pest problem, drawn to scale
See pricing
Treating on the window
Routine
One or two properly timed applications on a tree that keeps its canopy and never becomes a conversation about removal.
Treating after the damage shows
More, for less
More visits, a longer recovery, and a tree that spends two seasons looking rough while it grows back what it lost.
Not treating at all
$1,000 – $8,000
The removal, eventually, plus the stump and the shade the property no longer has. This is the number every treatment is measured against.
Removal figures are Eden's published range and vary with size and access. Treatment costs vary by species, tree size and how many rounds a season needs.

Common questions about pest and disease treatment
Ask us something elseHow do I know what is wrong with my tree?
Send a photo of the tree and a close photo of the damage. Between the species, where on the tree it started and the time of year, an arborist can usually name it before anybody drives out. When it is genuinely ambiguous, we say so rather than guess and spray.
Why does timing matter so much?
Almost everything on this page has a window measured in weeks. Fungal sprays protect new tissue and do nothing once infection has happened. Bagworm is vulnerable for about two weeks after hatch. Miss the window and the honest answer is to wait for next year rather than sell you an application that will not work.
Are the treatments safe around children and pets?
Applications are made by a licensed commercial applicator under Nebraska Department of Agriculture rules, and every product carries a re-entry interval we tell you before we start. For most treatments it is a matter of hours, and soil injections put nothing on surfaces at all.
Will one treatment fix it?
Sometimes. Bagworm caught at hatch is often one application. Needle cast is a multi-year commitment because the needles already lost do not grow back and the fungus is in the neighborhood, not just in your yard.
Do you spray the whole tree?
Only when the target is on the outside of it. Anything working under the bark, like a borer, is treated systemically through the trunk or the soil, because a spray cannot reach an insect that is already inside the wood.
Can you treat a tree you did not diagnose?
We will not apply anything on somebody else's diagnosis without looking first. It is not skepticism about the other opinion; it is that the wrong product at the wrong time is money spent for no result, and you are the one who paid for it.
What if the tree is already too far gone?
Then we tell you. A spruce that has lost its bottom two-thirds is not coming back, whatever gets sprayed on what is left. In that case the conversation is about replacement planting, not treatment.
How do I get on the schedule for next season?
Call 402-332-2839 or ask at any estimate. Timing-critical treatments are booked ahead by neighborhood, and being on the list is what makes hitting a two-week window possible.
Diagnosis is free, including when the answer is that nothing needs spraying.

The whole treatment side of the business, including the annual program.
Emerald Ash Borer Treatment
Its own page, because in this metro it is its own emergency.
Iron Injections
Yellow leaves with green veins are a deficiency, not a pest.
Deep Root Fertilization
A stressed tree gets hit hardest. Feeding is half of pest resistance.
Tree Risk Assessment
When the damage is far enough along to be a safety question.
Grub Control
The same Japanese beetles, one life stage earlier, in your lawn.
Spraying on a schedule is not the same as treating a tree
Meet the arboristsThere is a version of this service that is very easy to sell and almost useless: a truck arrives on a schedule that suits the company, sprays something broad-spectrum on everything in the yard, and leaves an invoice. It looks like care. It is mostly calendar management.
What actually decides whether a treatment works is narrower and less convenient. It is knowing which of two nearly identical spruce fungi you are looking at, because they are sprayed weeks apart. It is knowing that a bagworm is defenseless for about two weeks and untouchable after that. It is knowing that the beetle chewing a linden in July started as a grub in the lawn last fall, and that treating one without the other is half a job.
That knowledge is why treatment work at Eden is scheduled around soil temperature and degree days rather than around route convenience, and why we will tell you to wait until next April rather than sell you an application in August that we know will not do anything. Ask us what is wrong with the tree — 402-332-2839 — and the first answer is free, including when the answer is that it needs nothing.
