Yes, it is legal to keep a praying mantis as a pet almost everywhere in the United States, but the answer depends on which species you want and how you get it. Native mantises like the Carolina mantis can be kept without permits. Commonly sold non-natives like the Chinese and European mantis are widely available from domestic sellers and legal in most states. Exotic species shipped in from overseas, such as orchid or ghost mantises, are where federal permit rules kick in.
The Three Categories That Decide Your Answer
Before buying, figure out which of three buckets your mantis falls into. The legal picture is very different for each.
Native species. The Carolina mantis (Stagmomantis carolina) and other species native to North America face virtually no ownership restrictions for private individuals. You can catch one in your yard, keep it in an enclosure, and raise it without a permit.
Established non-natives. The Chinese mantis (Tenodera sinensis) and European mantis (Mantis religiosa) were introduced to North America more than a century ago and are now established across the continent. Garden supply companies sell them openly as pest control, and keeping one bought domestically is generally straightforward.
Exotic imports. Species like the orchid mantis (Hymenopus coronatus) and ghost mantis (Phyllocrania paradoxa) come from overseas. Importing them triggers federal permit requirements.
One practical note: a seller who lists something only as “praying mantis” without naming the species is a warning sign. Get the exact scientific name before you buy so you know which rules apply.
When Federal Law Actually Matters
Three federal frameworks touch mantis ownership, but none of them bans it outright, and most hobbyists never bump into any of them.
The Lacey Act makes it illegal to import, export, transport, sell, or acquire wildlife taken in violation of U.S., state, tribal, or foreign law.1U.S. Fish & Wildlife Service. Lacey Act It applies to insects. If a mantis was illegally collected abroad and shipped to you, possessing it can be a violation even without your knowledge of the original offense. The Act’s separate “injurious wildlife” provision at 18 U.S.C. 42 covers only mammals, birds, fish, amphibians, and reptiles, so insects can’t be banned under that section.2Office of the Law Revision Counsel. 18 U.S. Code 42 – Importation or Shipment of Injurious Mammals, Reptiles, and Other Wildlife
The Endangered Species Act covers insects but currently lists no praying mantis species as threatened or endangered, so it has no practical effect on mantis keepers right now.3US EPA. Summary of the Endangered Species Act
USDA’s Animal and Plant Health Inspection Service (APHIS) runs the PPQ 526 permit program for regulated organisms. The crucial detail for mantis keepers: the PPQ 526 instructions specifically exempt “entomophagous insects” (insect-eating insects, which includes mantises) from the interstate shipment permit requirement.4Reginfo.gov. Instructions for Completing PPQ Form 526 Importing an exotic mantis from another country is a different story and generally requires a permit, and APHIS lists “Invertebrate Pets” as a category under its permit program.5Animal and Plant Health Inspection Service. Regulated Organism and Soil Permits If you’re unsure whether a particular purchase needs a permit, APHIS recommends contacting them before you acquire the animal.
The short version: buying a domestically bred mantis and keeping it in your home state is the simple path. Overseas imports pull federal permits into play.
State, Local, and HOA Rules to Check
State laws on exotic animal ownership vary widely, and some states include insects in those frameworks. A handful restrict the importation or possession of non-native invertebrates to prevent ecological harm, and some require state-level permits on top of federal requirements. Your state’s department of agriculture or fish and wildlife agency is the right place to confirm the rules for the species you want.
Local governments add another layer. Some municipalities fold insects into “exotic animal” definitions in their zoning codes, which can mean permit requirements or outright prohibitions in certain residential zones. Homeowners associations sometimes restrict exotic pets through covenants and bylaws, and those restrictions are enforceable regardless of what state or federal law allows. Check with your local animal control office and, if you have one, your HOA.
Catching a Mantis Yourself
Collecting a native mantis from your own yard or private land where you have permission is generally fine. Federal land is different. National parks prohibit collecting any wildlife, including insects, without a research and collecting permit, and those permits go only to representatives of scientific or educational institutions and government agencies.6U.S. National Park Service. Research Policies and Guidance The underlying regulation, 36 CFR 2.1, prohibits possessing, removing, or disturbing any living or dead wildlife from its natural state on NPS lands.7eCFR. 36 CFR 2.1 – Preservation of Natural, Cultural and Archeological Resources National forests, BLM land, and other federal properties have their own rules, generally less restrictive but worth confirming.
One thing you should never do with any mantis you own: release a non-native species into the wild. Exotic mantises that escape or are released can compete with native species, prey on native mantises and other beneficial insects, and disrupt local ecosystems. Releasing regulated organisms without authorization can also trigger penalties under the Plant Protection Act.
About That $50 Fine for Killing a Mantis
A common piece of folklore holds that killing a praying mantis carries a fine, often said to be $50. No such federal or state law exists, and never has, including in Connecticut, where the European mantis is the official state insect. The myth has no statutory basis. It’s worth knowing if only so you don’t repeat it or worry about it.
What Happens If You Break the Import Rules
For a hobbyist keeping a common mantis at home, enforcement action is extremely unlikely. The penalties on the books, though, are serious for anyone importing exotic species or operating commercially.
Lacey Act civil penalties run up to $10,000 per violation. Criminal penalties for knowing violations involving sales, purchases, or imports reach $20,000 in fines and up to five years in prison.8Office of the Law Revision Counsel. 16 USC 3373 – Penalties and Sanctions The Plant Protection Act allows civil penalties up to $50,000 per individual for unauthorized movement of regulated organisms, with criminal penalties up to five years imprisonment for a first offense and ten years for subsequent convictions. A safety valve applies to small-scale violations: if an individual moves regulated articles without monetary gain, the initial civil penalty caps at $1,000.9Office of the Law Revision Counsel. 7 USC 7734 – Penalties for Violation
Seizure is the other risk. When federal agents seize illegally possessed exotic wildlife, the U.S. Fish and Wildlife Service runs formal forfeiture procedures. Live exotic, non-native animals seized inside the United States cannot be returned to the person who had them. The agency may send the animal back to its country of origin or to another country within its natural range, with the violator potentially on the hook for the costs.10Federal Register. Seizure and Forfeiture Procedures For someone who ordered a single exotic mantis from an overseas seller without the right paperwork, that means losing the animal and paying to ship it away.
If you want a mantis, the path with the fewest surprises is picking a species that’s native or already widely sold domestically, buying from a U.S. breeder, and running a quick check with your state agriculture department. Save the import route for cases where you’ve already confirmed the permit requirements and are willing to wait on APHIS.
