Large Pet Spiders

Large pet spiders means tarantulas and their close relatives, heavy-bodied spiders that sit still for hours in a burrow or on a piece of bark and ask very little of you day to day. They can be genuinely rewarding for people who like quiet observation, and a well-kept tarantula is hardy, long-lived and cheap to feed. They are not low-stakes, though. A secure enclosure prevents escapes, the wrong handling can end in a bite, and in Australia what you can legally keep depends on your state and the species. This guide covers pet tarantulas and other large, commonly kept spiders: what they need, what to avoid, and what to sort out before one comes home.

What Counts as a Large Pet Spider

In pet terms, "large" points to tarantulas (family Theraphosidae) and similar slow-moving terrestrial spiders kept in a terrarium. These are heavy-bodied animals that live in burrows or on bark and spend long stretches doing nothing at all. They can be tough when kept within their preferred temperature and humidity range, but they are still delicate: falls, dehydration, and stress from constant disturbance all do real harm.

It helps to separate pet-keeping from what you find in the backyard. Australia has medically significant spiders, including funnel-web spiders, that should never be treated as pets. Any suspected funnel-web bite is potentially dangerous and needs urgent medical care and correct first aid.^{1, 2}

Popular Pet Species

Some of the most commonly kept large spiders worldwide include:

• Chilean rose tarantula (Grammostola species): often described as hardy and generally calmer than many other tarantulas, though temperament varies by individual.
• Mexican redknee tarantula (Brachypelma hamorii): well known in the hobby, long-lived, slow-growing, and best treated as a look, don't handle animal.

Be cautious with dramatic claims about colour, size, and lifespan. Many tarantulas live for years, but longevity depends heavily on sex, species, and husbandry, and sellers sometimes overstate it.

Legality and Sourcing in Australia

Australia's wildlife laws are not uniform. What you can keep depends on your state or territory, and on whether the animal is native, captive-bred, or regulated as protected wildlife. Sort this out first, before you fall for a particular spider in a shop.

A quick checklist:

• Is the species legal where you live? Some jurisdictions regulate tarantulas and other invertebrates under wildlife frameworks. Queensland, for example, regulates native tarantulas (family Theraphosidae) under its animal licensing system.^{3, 4}
• Do you need a licence? In the ACT, most animals require a licence unless they are on an exempt list, and it is illegal to keep many animals without the right approval.⁵
• Are you buying from an approved source? Wildlife frameworks commonly require licensed sellers and documented captive breeding, particularly for native fauna.⁴

If you are unsure, start with your state or territory environment or wildlife licensing page. It is the fastest way to avoid buying an animal you cannot legally keep, sell, or transport later.

Housing and Enclosure

A large spider's enclosure comes down to three things: security, ventilation, and the right microclimate. The best-looking setup is a bad one if the lid can flex, the vents are wide enough for an escape, or the spider can climb high and fall.

• Escape-proof lid and vents: tarantulas are surprisingly strong, and they find small gaps.
• Low fall risk for terrestrial species: keep climbable height modest, because a fall can rupture the abdomen.
• Substrate and shelter: provide enough depth for burrowing species, plus a hide such as cork bark or a half-log.
• Water always available: a shallow, stable dish is usually safer than relying on misting alone.

Feeding

Most large pet spiders do well on appropriately sized insects, commonly crickets or cockroaches. The normal pattern is steady, unhurried feeding followed by long pauses. A tarantula that refuses food for a while is not automatically unwell, since moulting cycles and seasonal slow-downs both change appetite.

Avoid prey that can injure the spider. If live food is left unattended while the spider is preparing to moult, the risk goes up.

Handling

Large pet spiders are not built for frequent handling. Even docile individuals can flick urticating hairs (in some New World species), bolt without warning, or bite if pressed or startled. The bigger risk is usually to the spider: a short fall from hand height can be fatal.

If you must move a spider, use calm, controlled methods such as guiding it into a container, rather than lifting it with your hands.

Health and Safety

Most pet tarantulas are not considered medically significant to healthy adults, but bites can still be painful and can become infected, and allergic reactions are possible. Treat any bite seriously if symptoms escalate.

For Australian medically significant spiders, including funnel-webs and mouse spiders, the first aid and the urgency are different. Pressure immobilisation is recommended for a suspected funnel-web or mouse spider bite, and medical attention is essential.²

When a Pet Spider Is Actually a Wild Hazard

A funnel-web spider is not an exotic pet opportunity. It is a medically dangerous animal. The Australian Museum notes that funnel-web bites must be treated as potentially dangerous, and antivenom has been available since 1981.¹

If you find a funnel-web and you are in a region where safe collection programs operate, follow official guidance and prioritise safety. Antivenom supply relies on venom collection programs, including long-running efforts supported by public donations of spiders in NSW.⁶

The Bottom Line

Large pet spiders suit people who enjoy quiet observation: a well-made enclosure, steady conditions, and small routines done carefully. Get the legal side clear first, buy from a reputable source, and set up the habitat before the spider arrives. Then leave it room to be what it is, an animal that survives by staying still, sensing vibrations, and choosing the safest corner.
