Gypsy Moth Quarantine
Counties that have an established population of gypsy moths are quarantined and are issued regulations.

2009 Wisconsin Quarantine Map

What is a quarantine?
A gypsy moth quarantine is a system of rules administered by the USDA Animal and Plant Health Inspection Service and the Department of Agriculture, Trade and Consumer Protection. The rules are intended to prevent the spread of gypsy moth from infested areas to non-infested areas. People moving outdoor materials and woody products can inadvertently transfer these egg masses to new areas.

How does an area become quarantined?
To be quarantined, a county must have several years of high trap catches (10 or more males per trap) or an established breeding population.

Each year, statewide trapping and egg mass survey data is compiled. Based on this data, additional counties may be considered for quarantine. All of eastern Wisconsin is under quarantine for gypsy moth.

Gypsy Moth Regulations
It is illegal to move or transport any wood product or outdoor household articles that have been exposed to gypsy moth from a quarantined area to a non-quarantined area without inspection or certification, ATCP statute 21.10 (PDF).

The following regulated articles require inspection and certification:

• Logs, posts, pulpwood, bark and bark products
• Nursery stock
• Christmas trees
• Outdoor Household Articles (OHAs)
• Mobile homes and associated items

The movement of regulated articles from a generally infested area into or through a non-infested area will require documentation by one of the following:

• Plant Protection and Quarantine (PPQ) Form 540 (Certificate)
• PPQ Form 530 (Limited Permit)
• A signed “Accurate Statement” (for logs, pulpwood, and woodchips)
• Self-Inspection Check List from Program Aid Number 1329 “Don't Move Gypsy Moth” (for OHAs)
• PPQ Form 527 (Sticky Back Certificate) (for nursery stock)
• Rubber Stamp Certificate (for nursery stock)
• Qualified Certified Applicator Document (for OHAs and mobile homes)

If establishments regularly ship large quantities of regulated articles outside the generally infested area, the establishments must operate under a Compliance Agreement. If establishments infrequently ship regulated articles from a generally infested area, PPQ and/or State personnel will inspect and certify individual shipments.

What is an Accurate Statement?
It is a document, prepared by an employee of an establishment operating under a Compliance Agreement, which will allow the establishment to ship logs, pulpwood and/or wood chips. Along with other items, the Accurate Statement includes a certifying statement, information on the type of regulated article, the amount and/or number of regulated articles, and the signature of the inspecting employee.

What is a Compliance Agreement?
It is an official document which specifies the conditions to be followed for growing, handling or moving regulated articles. An example would be a written agreement between a shipper (a person or company) engaged in handling or moving regulated articles; in the agreement, the shipper of the regulated articles agrees to comply with certain requirements to allow shipment of the regulated articles.

What is a Qualified Certified Applicator Document?
It is the document used by a pest control operator who is certified by the State or the USDA for the interstate movement of outdoor household articles.

Through inspection and treatment of regulated articles, the risk of transporting gypsy moth to non-infested areas is minimized.

Firewood and Gypsy Moth
Firewood is an ideal place for gypsy moth as well as other invasive pests. The Wisconsin Department of Natural Resources prohibits the movement of firewood from outside Wisconsin.

Firewood must be purchased at or within a 50-mile radius of the destination site. Quarantined areas are excluded in the 50-mile radius. Otherwise, it must be purchased from a DATCP certified firewood vendor or at the destination site. All firewood purchased must be burned on site.
