Tree Pest Outbreak Marketing: Ash Borer, Lanternfly, and Dead Trees

More than 99% of ash trees hit hard by emerald ash borer die, usually within two to four years. The beetle is now confirmed in 38 states. Which means somewhere in your service area right now, entire streets of ash are already on a countdown nobody has told the homeowner about.

That’s the odd thing about pest outbreak marketing. The removals are effectively already booked. The only open question is who gets the call.

Why a Pest Outbreak Concentrates Removal Work Block by Block

A storm hits a wide area all at once. A pest moves differently, and that difference is the whole opportunity.

Ash borer spreads tree to tree and street to street. Where a subdivision was planted with ash down both sides of the road in the 1980s (and thousands of American subdivisions were), that subdivision dies together. The neighborhood one mile over, planted in maple, stays green.

Oak wilt behaves even more locally. University of Minnesota Extension describes it moving underground through grafted root systems between neighboring oaks, which is why it takes out a cluster of trees rather than a scattered few.

So you get demand that is concentrated, predictable, and geographically tight.

That is the exact shape of demand a mailer is built for. The Cary Institute of Ecosystem Studies puts all of North America’s 8 billion-plus ash trees at risk from the beetle, with over 99% dying in severe infestations and heavily infested trees usually gone in two to four years. Those trees are not spread evenly across your service area. They are bunched.

Emerald Ash Borer Is the Outbreak That Actually Pays

USDA APHIS has confirmed emerald ash borer in 38 states and the District of Columbia, and it removed the federal domestic quarantine on the beetle effective January 2021. Translation: this stopped being a containment problem and became a permanent condition of doing tree work in most of the country.

Why does that matter for your marketing?

Because a dead ash is not optional work. A homeowner can put off a trim for three years and nothing happens. A standing dead ash over the driveway is brittle, fails without warning, and their insurance carrier already knows it. That’s a removal at full ticket, not a $300 trim.

Ash borer hands you the highest-value job on your menu, pre-qualified by a beetle.

The catch is that the homeowner usually does not know what they are looking at. They see a thin canopy and assume drought. That gap between what the tree is doing and what the owner understands is where your letter earns its money.

Spotted Lanternfly Gets the Headlines. Ash Borer Gets the Removals.

Here is where tree services waste money on pest outbreak marketing.

Spotted lanternfly is the pest everyone has heard of. It’s on the local news, homeowners ask about it constantly, and half your competitors are printing it on flyers this fall. Penn State Extension, which has tracked the insect since it landed in Pennsylvania, is blunt about the damage: scientists have documented it killing only grapevines, tree of heaven, and black walnut saplings, and healthy, established ornamental trees have not been recorded dying from spotted lanternfly.

Read that twice before you build a campaign on it.

Lanternfly produces a ringing phone and a thin invoice. Somebody wants to know what the bugs on their maple are, you drive out, you tell them the tree is fine, and you’ve spent an hour to give away free information. Ash borer produces removals.

Asian longhorned beetle sits at the opposite end. APHIS states plainly that infested trees cannot be treated or saved, and that the only way to destroy the insect is to remove the tree and chip or incinerate the wood. That’s mandatory removal work, though it’s confined to active quarantine zones in Massachusetts, New York, Ohio, and South Carolina.

Know which one is in your market before you write a word of copy.

What Each Major Tree Pest Means for Your Schedule

Not every outbreak is a marketing opportunity. Some are, some generate calls you’d rather not drive to, and telling them apart before you spend on mail is most of the work.

Pest or disease	What it kills	Can the tree be saved?	What the work actually is	Where it matters
Emerald ash borer	Ash, every North American species	Only with repeat treatment, and not once decline sets in	Full removals, often several per street	38 states and DC, per APHIS
Asian longhorned beetle	Maple and other hardwoods	No, removal is the only control	Mandatory removal plus chipping or incineration	Quarantine zones in MA, NY, OH, SC
Oak wilt	Red oak group, fast	Rarely once a red oak is infected	Removals in clusters, plus strict pruning windows	Midwest and Texas
Hemlock woolly adelgid	Eastern and Carolina hemlock	Treatable if caught early	Removals in untreated stands, treatment plans elsewhere	Eastern US
Spotted lanternfly	Grapevines, tree of heaven, black walnut saplings	Established ornamentals survive it	Nuisance calls and tree-of-heaven work	PA and surrounding states

Read the third column and the strategy writes itself. Where the answer is “no,” you are marketing a removal. Where the answer is “treatable,” you are marketing an inspection and a plan, which is real revenue but a completely different message and a completely different ticket.

Get those two mixed up in one mailer and the piece says nothing to anybody.

How to Target Pest Outbreak Marketing to the Right Carrier Routes

Most companies handle an outbreak at the wrong altitude. The extension office announces the county has ash borer, so they mail the county.

An outbreak is not a county-level event. It’s a street-level event.

This is where route-level data does the actual work. Tree Traction analyzes 295 data points per carrier route, including satellite-measured tree density and canopy coverage, and we’re the only company in the country with tree density at the carrier route level. So instead of blanketing a zip code because a press release mentioned your county, you concentrate letters on the routes where the canopy is thick and the properties are big enough that a removal is a four-figure job.

Then every route gets its own tracking phone number, so after the first blast you know which neighborhoods answered and which ones stayed quiet. Across our client base, roughly 75% of calls come from about 50% of the routes mailed. During an outbreak that spread is even wider, because the infestation itself is clustered.

Matt Morovic with Upright Tree Care in Wisconsin 10x’d his marketing spend in his first month, and the part he talks about is the calendar: he runs five quotes in two hours because they’re all in the same neighborhood. A pest die-off is that same geographic clustering, handed to you by an insect instead of engineered by a mail plan.

Your crew works one street instead of three counties. That’s margin, not just convenience.

What a Pest Outbreak Mailer Should Say (And What It Shouldn’t)

Do not lead with the Latin name. No homeowner is searching for Agrilus planipennis.

Lead with what they can see standing in their own driveway. Thinning at the top of the canopy while the lower branches look fine. Sprouts shooting straight out of the trunk. Woodpeckers tearing strips of bark off. Once a homeowner matches a symptom on your letter to the tree in their yard, they call, and they call the company that told them what they were looking at.

A pest outbreak mailer needs three things the rest of your mail doesn’t:

• A plain-language symptom list with the species named, so the homeowner can self-diagnose in ten seconds
• An honest statement of what can still be treated and what cannot, because overclaiming on either side kills trust fast
• An offer to look at the tree, not a price, since a dead ash near a structure prices very differently than one in an open back yard

That third point is where companies talk themselves out of money. Never quote a hazard removal over the phone. The whole job of the letter is to earn a walk-up, the same way it does on any good direct mail piece.

And never write copy claiming a tree is dangerous when nobody has looked at it. Fear-first mail gets remembered as the mail that lied.

When to Run Pest Outbreak Marketing on the Infestation Curve

Timing is what separates the companies that own an outbreak from the ones cleaning up behind it.

The leading edge comes first, when the beetle has been confirmed nearby but most trees still look healthy. Mail here is about treatment and early inspection, and it’s the cheapest time to establish yourself as the company that knows the pest. Very few competitors are mailing yet.

Then comes peak mortality, which for ash borer runs several years behind first detection. This is the removal window and the one worth spending real money on. It’s also when every competitor wakes up, which is exactly why the routes you already mailed matter: you’re a name they recognize instead of a stranger with a flyer.

The tail is last, when the standing dead are gone and what’s left is stumps and replanting. Different message, smaller ticket, still worth a mailing.

Mail only during peak and you arrive the same week as everyone else. Consistency is what wins outbreaks, the same way it wins slow seasons.

Don’t Build the Whole Business on a Beetle

Now the honest part, because somebody has to say it.

An outbreak is finite. Once the ash in a market is dead and cleared, that demand is gone and it does not come back. Companies that staffed up entirely on ash removal and marketed nothing else have watched the phone go quiet two years later with a payroll built for a boom.

Treat a pest outbreak as a message inside a program that was already running.

The mailing keeps going after the beetle is finished, with the message swinging back to removals and trims, storm work, and seasonal offers. Direct mail averaged a 4.4% response rate in the ANA/DMA 2025 Response Rate Report, and that baseline does not depend on an insect cooperating. The outbreak is a spike on top of a channel that works anyway. That’s the whole case for running mail continuously instead of in bursts.

The routes you learned during the outbreak are the real asset. You now know which neighborhoods answer your letter, and that knowledge outlives the beetle by a decade.

Find the Streets Before the Trees Fall

Pest outbreak marketing comes down to one skill: knowing which specific streets are about to need removals, and getting a letter there before the canopy makes it obvious to everybody.

Ash borer is the one paying for removals in most of the country. Lanternfly is noise. And the difference between mailing a county and mailing the right forty carrier routes inside it is the difference between a busy phone and a booked schedule.
