SLF FORBUSINESS

Spotted lanternfly creates compliance obligations, operational disruptions, and reputational risks for businesses in infested zones. This guide covers what you're legally required to do, what you should do, and how to protect your property and customer experience.

Compliance requirements vary by business type. Nurseries, landscaping companies, and businesses moving regulated articles out of quarantine zones have formal USDA compliance obligations. Most other businesses do not — but still face real operational and reputational risks.

The USDA Compliance Agreement

If your business moves regulated articles — plants, soil, wood products, outdoor equipment — out of an SLF quarantine zone, you likely need a USDA APHIS compliance agreement. Here's what that means.

What Is a Compliance Agreement?

A USDA APHIS compliance agreement is a voluntary agreement between your business and USDA that allows you to legally move regulated articles out of a quarantine zone, provided you follow specific inspection and documentation protocols. Without it, moving regulated articles out of a quarantine zone violates federal quarantine regulations.

Penalties for Non-Compliance

Moving regulated articles out of an SLF quarantine zone without a compliance agreement or in violation of an existing agreement can result in civil penalties up to $7,700 per violation under the Plant Protection Act. Criminal penalties are available for willful violations.

To get started: Contact your USDA APHIS State Plant Health Director. Find your state's contact at aphis.usda.gov or through your state department of agriculture. They will guide you through the agreement process at no cost.

Getting a Compliance Agreement: Steps

1
Determine if you're in or near a quarantine zone
Quarantine zones are established at the county level by USDA APHIS. If your business is in a quarantined county — or regularly moves regulated articles out of one — you need to evaluate your compliance status.
2
Identify your regulated articles
Regulated articles include: living plants, cut logs and brush, bark and wood chips, landscaping and outdoor household items, nursery stock, and any material that could harbor SLF or egg masses. If your business moves these, you may need an agreement.
3
Contact your USDA APHIS State Plant Health Director
The compliance agreement is issued by USDA APHIS. Call your state's Plant Health Director office to initiate. They will walk you through the self-inspection protocol requirements and document requirements for your business type.
4
Train your staff on SLF inspection
The compliance agreement requires that you have trained employees capable of conducting SLF inspections of regulated articles before they leave your facility or quarantine zone. USDA and your state ag extension office provide free training resources.
5
Keep inspection records
Compliance agreements require documentation of inspections. Maintain a log of what was inspected, by whom, when, and the result. These records may be audited by USDA or state inspectors.

Which Businesses Need to Worry Most

SLF compliance and operational risk is not equal across industries. These business types face the highest exposure.

Nurseries and Garden Centers

Highest risk

Any business that grows, sells, or transports plants — particularly container stock, balled-and-burlapped trees, or live plant material — is subject to the most stringent SLF compliance requirements. Compliance agreements are generally mandatory for nurseries in quarantine zones that ship product.

Landscaping Companies

High risk

Companies that transport equipment, mulch, soil, and plant material across county lines are regulated articles handlers. Any SLF-infested material moved without compliance with quarantine rules is a violation. Employee inspection training is essential.

Timber and Lumber Operations

High risk

Timber harvesting in SLF zones and the movement of logs, lumber, bark chips, and wood waste out of quarantine areas is regulated. Saw mills and lumber yards in infested areas should contact their USDA APHIS state plant health director to confirm their compliance status.

Moving Companies

Moderate risk

Moving companies transporting household goods out of SLF quarantine zones — including outdoor furniture, planters, firewood, and vehicles — are moving potential SLF-infested material. USDA compliance agreements are recommended for companies with regular routes out of quarantine zones.

Parking and Vehicle Fleets

Moderate risk

Businesses with large vehicle fleets or commercial parking facilities in SLF zones are major unintentional spread vectors. Vehicles parked under infested trees accumulate egg masses on horizontal surfaces. Fleet managers should include SLF inspection in seasonal vehicle maintenance protocols.

Outdoor Dining Businesses

Restaurants, cafes, and bars with outdoor seating face the most customer-visible SLF impacts. Managing this proactively is critical to protecting revenue during peak season.

The Honeydew and Wasp Problem

SLF honeydew drips from infested trees and coats outdoor seating, table surfaces, and the floor of any outdoor dining space below a heavily infested canopy. Fermenting honeydew draws yellow jackets in large numbers — creating a hazardous dining environment in August and September.

Customer Experience Impact

Customers encountering SLF adults crawling on table surfaces, chairs, or the exterior building wall — particularly in large numbers — will leave and not return. One viral social media post about SLF at a restaurant can create outsized reputational damage during peak season.

Treat the Source Trees

The most effective outdoor dining protection is trunk injection of infested trees over the seating area. A licensed arborist can apply imidacloprid or dinotefuran via trunk injection in spring; the systemic treatment reduces feeding pressure through the summer. This must be done by spring for that season's protection.

Daily Honeydew Cleanup

During peak season, plan for daily table and chair wipe-down of any honeydew accumulation before service. Power washing the floor area weekly prevents sooty mold establishment on concrete and pavers. This is an ongoing operational cost in heavily infested areas.

Physical Canopy Management

If tree injection is not feasible before peak season, consider temporary overhead netting or a canopy cover for outdoor seating. This won't stop SLF entirely but significantly reduces insect and honeydew accumulation on tables.

Staff Briefing

Brief servers and hosts at the start of SLF season on how to respond when customers notice SLF — a prepared, calm explanation that it's a regional pest (not a food safety issue) and that the restaurant is managing it is far better than an uninformed response.

Office and Retail Property Managers

Commercial property managers have a responsibility to tenants and visitors to manage the SLF experience on their properties during peak season.

Parking Lot Ornamental Trees

Ornamental trees in parking lots — particularly Callery pear, willow, and any Tree of Heaven that has been allowed to establish — are significant SLF hosts. If your parking lot trees show heavy SLF clustering in late summer, trunk injection in the following spring is the most effective management option.

Tenant Communication

Building managers in SLF zones should brief tenants at the start of each SLF season (July) so they understand what to expect. A one-paragraph notice that SLF will be visible on building exteriors in August and September, that it poses no health risk, and what steps management is taking goes a long way toward preventing tenant alarm.

Building Entry Management

SLF adults congregate on warm south-facing building walls in September and October. Staff entries and customer-facing entrances should be swept of SLF adults before business hours during peak season. Brief facility staff on what they're looking at and how to remove them.

When to Hire a PMC

A pest management company (PMC) with SLF experience can provide perimeter treatment of the building exterior and parking lot that reduces adult clustering. This is most cost-effective for buildings with high-visibility customer entrances. Request a treatment plan specific to SLF — not a generic perimeter spray service.

Employee Communication

Employees who travel between infested and non-infested areas — whether for deliveries, service calls, or field work — are potential SLF spread vectors. Brief them on the basics.

Field Staff and Delivery Drivers

Employees who park vehicles in SLF-infested areas should be trained to check wheel wells and undercarriages for egg masses during fall (October–November) before driving to new territories.

Construction and Trade Workers

Workers who carry tools and equipment between job sites should inspect tool cases, ladders, and equipment racks for egg masses during fall. This is especially relevant for contractors working in different counties.

Warehouse and Loading Dock Staff

Staff who handle outdoor-stored materials, pallets, and equipment should know what SLF egg masses look like. A brief seasonal safety talk with photos takes 10 minutes and can prevent an interstate compliance violation.

Remote and Traveling Staff

Employees who travel between SLF infested and non-infested states should be aware that transporting certain outdoor items (potted plants, firewood, outdoor equipment) may have quarantine implications.

How to Report a Sighting

Give employees a one-line reporting protocol: photograph, note the location, and send to [designated contact]. If they spot SLF in a new area, that information is valuable. Make it easy to report.

Free Training Resources

USDA APHIS offers free SLF inspection training materials for businesses. Penn State Extension and Rutgers Extension both have free video and PDF training tools appropriate for staff briefings.

The Liability Question

Businesses are not generally liable for SLF present on their property — but there are exceptions and reputational risks that matter.

No General Liability for Passive SLF

Businesses are not currently liable for spotted lanternfly naturally present on their property. SLF infestations are treated as an environmental condition, not a property defect or maintenance failure in current legal frameworks.

Compliance Violations Are Different

If your business has a USDA compliance agreement and fails to follow it — moving uninspected regulated articles out of a quarantine zone — you face real legal exposure. Compliance violations are a different matter from passive infestation liability.

Reputational Risk Is Real

Customer-visible SLF infestations — particularly at restaurants, retail, or hospitality properties — create reputational risk through online reviews and social media. This is not a legal liability but is a business risk that should be managed proactively during peak season.

Emerging Legal Landscape

SLF quarantine law is still evolving. States may enact additional property owner obligations as the science matures and political pressure grows from agricultural interests. Staying current with your state ag department's guidance is advisable.

USDA APHIS contact: For compliance agreement questions, call your USDA APHIS State Plant Health Director. You can find your state office at aphis.usda.gov/plant-health/state-contacts. They can advise on whether your business operations require a compliance agreement and what the specific requirements are for your industry.
