Are Roof Rats Legal in American Samoa? Keeping, Breeding & Selling

Roof Rat LawsUnited States › American Samoa

Summary. American Samoa is effectively a closed door for a pet roof rat. IMPORT is functionally prohibited: the Department of Agriculture’s quarantine code (ASAC Title 24, Ch. 3) bans the importation of ‘miscellaneous pets’ (ASAC 24.0318), the ‘domestic animal’ import list (ASAC 24.0320) is a closed list of agricultural/working animals that does NOT include any rat, and any non-domestic animal may be imported only with the Governor’s prior written permission (ASAC 24.0315), a waiver that is, in practice, reserved for scientific/laboratory use and essentially never granted for a pet rodent. There is no on-island quarantine facility, so a non-compliant animal is returned to origin at the owner’s expense or destroyed. WITHIN the territory there is no wildlife-possession permit scheme for pet rats (keep/breed/sell are not separately licensed), so those activities sit in an unregulated legal void, but that void is legally perilous: ASAC Title 25, Ch. 21 (Rodent Control, ASAC 25.2101) imposes an affirmative duty on every building owner/occupant to eradicate rodents and to deny them food and harborage, with no carve-out for a caged, domesticated rat, and ASAC 24.1104 lists ‘rats and mice’ as pest species that may be killed at any time without a permit. The code makes NO distinction between wild R. rattus and a captive-bred ‘fancy’ rat (or even R. norvegicus), taxonomically indifferent. Maintaining a public-health nuisance after a 10-day abatement notice is a class C misdemeanor (ASAC 25.0107). The traditional matai/village by-law system adds a further enforceable layer on communal land. Never release a roof rat (it is a documented, federally targeted invasive that devastates native Pacific birds).

Status by activity

Keeping / owning   Unregulated / unclear

Confidence: Medium · Last verified 2026-06-12

No wildlife-possession permit or ‘banned-to-keep’ species statute exists for pet rats, so in-territory keeping is not separately licensed, BUT it is legally perilous, not safely permissive. ASAC 25.2101 (Rodent Control) imposes an affirmative duty on ‘every owner, lessee, or occupant of an occupied building’ to eradicate rodents ‘by poisoning, trapping, fumigation or other appropriate means’ and to keep premises ‘free from foodstuffs… and other material which may serve as food or harborage for rodents,’ with NO carve-out for a caged, domesticated rat, so a clean pet enclosure is textually indistinguishable from an illegal rodent harborage. ASAC 24.1104 separately classifies ‘rats and mice’ as pest species takeable at any time without a permit. Maintaining a public-health nuisance after a 10-day notice to abate is a class C misdemeanor (ASAC 25.0107). Whether Health actually treats a secure indoor pet as a ‘harborage’ is the open enforcement question.

Breeding   Unregulated / unclear

Confidence: Low · Last verified 2026-06-12

The ASAC contains no statute regulating or licensing the private propagation of small mammals, and no hobbyist-breeder carve-out for non-traditional pets, so breeding is technically unregulated. But it is the most legally hostile of the in-territory activities: intentionally increasing the population of a species the government is actively trying to suppress (ASAC 24.1104 lists rats/mice as pests takeable at will; federal eradication programs are underway) cuts directly against public policy, and breeding still requires keeping, which carries the ASAC 25.2101 harborage problem. A breeding operation would also be exposed to the broad public-health nuisance definition in ASAC 13.0203(31). With no legal way to import founder stock, establishing breeding stock is in any case a practical impossibility.

Selling or giving away   Unregulated / unclear

Confidence: Low · Last verified 2026-06-12

There is no pet-dealer or rodent-specific licensing statute, and the quarantine chapter is silent on the local sale/gifting of an animal already lawfully present, so intra-territory transfer is unaddressed by specific point-of-sale law. Practically, however, selling/gifting a rat transfers the ASAC 25.2101 nuisance/eradication liability to the buyer, and any commercial enterprise would need a general business license from the Department of Commerce (DOC), whose issuance requires compliance with health/environmental rules and would trigger Department of Health / Environmental Quality Commission review, almost certainly denied given the territory’s active rat-eradication posture. Because lawful import of founder stock is closed, a commercial breeding/sale operation is practically impossible to establish.

Transport & import   Prohibited

Importing a roof rat into American Samoa is functionally prohibited. ASAC 24.0318 expressly prohibits the importation of ‘miscellaneous pets’, a banned catch-all for non-traditional domestic animals into which pet rodents fall. The ‘domestic animals’ eligible for routine import are an exhaustive closed list (ASAC 24.0320: ruminants, horses/mules/asses, swine, domestic poultry) that does NOT include any rat. A non-domestic animal may be imported only with ‘the prior written permission of the Governor’ (ASAC 24.0315), a waiver realistically reserved for scientific/laboratory imports, not pets. American Samoa has no quarantine facility (unlike Hawaii), so a non-compliant or unauthorized animal is immediately returned to origin at the owner’s expense or destroyed. The species is treated firmly as an invasive pest at the border, not as a permissible companion animal. (American Samoa is outside the U.S. customs territory; a shipment routed through a U.S. designated port would also implicate federal USFWS rules, but the territorial import bar is dispositive.) Never release a roof rat.

Restrictions & responsibilities

Importing a roof rat into American Samoa is functionally prohibited. Pet rodents fall under the banned ‘miscellaneous pet’ class (ASAC 24.0318); rats are absent from the closed ‘domestic animal’ import list (ASAC 24.0320); and a non-domestic animal can enter only with the Governor’s prior written permission (ASAC 24.0315), which is realistically reserved for scientific/laboratory imports. There is no quarantine facility, so a non-compliant animal is returned to origin at the owner’s expense or destroyed. Do not ship a pet rat to American Samoa expecting entry.
  • Treat import as effectively closed: a pet roof rat is a prohibited ‘miscellaneous pet’ and is not on the domestic-animal import list
  • The only theoretical route is the Governor’s prior written permission (ASAC 24.0315), confirm in writing with the Dept of Agriculture Quarantine office before any shipment; expect denial for a pet rodent
  • If denied or non-compliant: there is no on-island quarantine, so the animal is returned at your expense or destroyed, do not attempt entry on spec
  • Never release a roof rat (documented invasive; active eradication programs)

Public-health ‘rodent harborage’ hazard. ASAC 25.2101 imposes an affirmative duty on every building owner/occupant to eradicate rodents and to keep premises free of food and harborage, with no exemption for a caged domesticated rat, so a pet enclosure can be read as an illegal rodent harborage. ASAC 24.1104 lists rats/mice as pest species takeable at any time without a permit. Maintaining a public-health nuisance after a 10-day notice to abate is a class C misdemeanor (ASAC 25.0107). Keep enclosures secure and sanitary; understand that enforcement could compel removal/destruction of the animal.
  • Understand that no possession permit exists, but the rodent-eradication duty (ASAC 25.2101) can be read to reach a caged pet rat
  • Keep any rat strictly contained, clean, and odor-free to minimize nuisance-complaint exposure
  • Confirm with the Dept of Health whether a secure indoor pet enclosure is treated as a regulated ‘harborage’ before relying on the gap

Traditional governance layer. Most land in American Samoa is communal native land under the matai (chief) system (ASAC Title 37), and villages enforce by-laws via Village Monitoring & Enforcement Committees. A matai or village council edict to clear ‘isumu (rats/mice) harborage on communal land carries enforceable weight under the territorial statutes protecting traditional governance, and an individual without freehold rights has little recourse. This is a real, non-statutory hurdle to keeping a pet rat on communal land.
