How Much Does a Praying Mantis Really Cost?

How Much Does a Praying Mantis Really Cost?

Praying mantises are one of the most affordable exotic pets available, genuinely cheap to buy and cheap to keep, with one important caveat about how long you'll actually have one. For the full care picture beyond budgeting, see our complete Praying Mantis care guide.

The Mantis: $15 to $150

Common species like Carolina and Chinese mantises run $15 to $35. Ghost mantises run $15 to $75 depending on age and quality. Orchid mantises, prized for their striking appearance, can reach $150. Most species stay well under $75 even as full adults.

Buy an adult or subadult, not a nymph. Nymphs are genuinely difficult to keep alive through their many molts, and a beginner is much better served starting with an animal that's already past that fragile early stage.

Upfront Setup: Roughly $50 to $150

Item	Cost Range
The mantis itself (adult or subadult)	$15 - $75 (up to $150 for orchid mantises)
Tall mesh or acrylic enclosure	$60 - $70
Coconut fiber and peat substrate	$10 - $16
Branches and climbing structures	$15 - $30
Mist system or spray bottle (optional)	$7 - $12
Feeding tongs (fine-tip precision, optional)	$10 - $18

A properly sized enclosure, taller than it is wide, matters more for this species than almost any other invertebrate, more detail on exactly why is in our Praying Mantis enclosure setup guide. Branches or mesh double as both a climbing surface and the anchor point for a safe molt, so this is one line item, not two. Altogether, most first-time setups land around $50 to $150.

Ongoing Costs: Roughly $10 to $40 a Month

Live feeder insects are the main expense. Fruit fly cultures run $5 to $10 each, and crickets cost roughly 10 to 50 cents apiece depending on size. Occasional supplements round out the monthly total. Feeder insects are perishable and bought as needed rather than stocked up front, so this cost stays a steady, modest monthly line rather than a big one-time purchase.

Vet Costs

Essentially none. Exotic vets rarely treat invertebrates, and mantis care is entirely husbandry-based. Correct humidity, proper feeding, and careful handling around molting time do far more for a mantis's health than any veterinary intervention could, our Praying Mantis health issues guide covers exactly what that husbandry looks like in practice.

Lifespan: Short, and Worth Knowing Upfront

This is the detail that matters most for setting expectations. Most commonly kept mantis species live just 6 to 12 months total, Chinese mantises toward 8 to 12 months, African mantises closer to 6 to 9 months, with females typically outliving males. A small number of species can reach around 18 months under excellent care.

It's worth going into mantis keeping with that expectation rather than being caught off guard by it. If you're weighing this against other invertebrates, our Tarantula cost guide and Emperor Scorpion cost guide sit at the opposite end of the spectrum, both are multi-year to multi-decade commitments on a similarly small budget. Once the short timeline makes sense for you, see our Praying Mantis handling guide for what day-to-day interaction actually looks like, or browse the rest of our Invertebrates care guide category for more.
