Pumpkin Patch Tarantula

Hapalopus formosus

Why We Love Them: The Pumpkin Patch tarantula is widely considered one of the most beautiful dwarf tarantulas in the hobby. They feature a striking, intricate pattern of bright orange "pumpkins" and black patches on their abdomen. Despite being burrowers, they are very active and will cover their entire enclosure in thick sheets of white webbing, often sitting right out in the open on display.
Lifespan Females 8-10 years / Males 2-3 years
Adult Size 2.5-4 inch leg span (Dwarf)
Enclosure Small/Medium Acrylic Enclosure (2.5 to 5-Gallon)
Warm / Basking 72°–80°F
Cool Side 68°–72°F Night
Humidity / Water 70-80% (Moderate-High)

Species Profile & Temperament

TraitOverview
OriginTropical rainforests of Colombia
Diet TypeInsectivore (Crickets, Roaches, Mealworms)
ActivityNocturnal / Crepuscular (However, they are a highly visible "display" species)
TemperamentBold and confident, but extremely fast and skittish.
HandleabilityNot recommended. They are incredibly small, light, and fast.
VenomAsk your doctor about any bite. Wash a bite that breaks the skin with soap and water.
Urticating HairsYes (Can flick hairs from abdomen if stressed, though they prefer to run)
Difficulty2/5 — Easy (Easy care, but their tiny size and lightning speed can intimidate true beginners)
Hardiness3/5 — Moderate (Requires a balance of moisture without becoming a swamp)

Safety Information

Defense: If startled, their first instinct is to run at lightning speed into their burrow. They do possess urticating hairs, but they rarely kick them, relying almost entirely on their speed to escape threats.
Handling Precautions: Do not handle this species. Because they are a dwarf species, they are incredibly fragile. A fall from a human hand to a table or floor can kill them. Also, they are so fast that if they bolt, you may never catch them.

Housing & Enclosure

Enclosure Type & Size

  • Type: Terrestrial / Opportunistic Burrower / Heavy Webber.
  • Minimum: Because they are a dwarf species, they do not need much room. A small acrylic or glass enclosure is plenty of space for a full-grown adult. Ask us in store about the right size.
  • Ventilation: Good cross-ventilation is absolutely required to prevent mold, as they require a slightly damp environment.

Substrate

  • Recommended: Coconut fiber (Eco Earth), peat moss, or organic topsoil.
  • Depth: Provide substrate deep enough to burrow. They love to dig and will construct elaborate burrows that connect to their surface webbing.

Décor & Enrichment

  • Hides & Anchor Points (CRITICAL): Provide a curved cork bark hide as a starting point for their burrow. You must also add fake plants, small twigs, or upright cork bark around the hide—they need these vertical anchor points to construct their massive web hammocks.
  • Water Dish: Provide a tiny, shallow water dish. If it is too deep, use a small bottle cap.

Temperature

ZoneTemperature
AmbientComfortable room temperature
  • Heating: Room temperature is usually fine. If your house is cold, use a small heat pad mounted on the SIDE of the tank, never underneath.

Humidity

  • Target Range: Slightly damp on the water-dish side, drier on the other side.
  • How to Maintain: They are moisture-dependent, especially as spiderlings. Keep one half of the enclosure (the side with the water dish) slightly damp by letting the dish overflow a little. Allow the top layers of the soil on the other half to dry out to prevent stagnant air.

Diet & Nutrition

Pumpkin Patch tarantulas are fierce, confident eaters with a fantastic feeding response. They grow very quickly.

Primary Diet

  • Live crickets, dubia roaches, or mealworms. Ask us in store what feeder size fits your spider.

Feeding Schedule

Ask us in store how often to feed your spider and what size feeder fits it.

Pre-Molt Fasting

  • If they seal the entrance to their burrow with heavy webbing and dirt, they are in pre-molt. Do not dig them up. Leave them completely alone until they emerge on their own.

Molting

During the Molt

  • DO NOT disturb the spider. They will molt safely inside their webbed-up burrow.
  • Remove any live crickets from the enclosure immediately.

Post-Molt Care

  • Wait until the new fangs have turned dark and hard before offering food. Ask us in store if you are unsure.

How We Keep Them at Critter Cabana & Gresham Pet Supply

  • Oregon Winter Furnace Air vs. Molting Humidity: When Pacific Northwest furnaces kick on from October through April, indoor room humidity drops fast and dries out small enclosures from the top down. Rather than misting the spider or invert directly (which stresses terrestrial species and invites stagnant mold), we keep Pumpkin Patch Tarantula by using a deep moisture-retaining substrate bed (ReptiSoil + Coco Fiber + Sphagnum Moss), overflowing the water dish slightly into one corner, and maintaining cross-ventilation.
  • Safe Room Heating in the Willamette Valley: If your house gets cold on winter nights, never stick a heat pad on the bottom of a burrowing invertebrate tank—they dig down to escape heat and will cook themselves. Use a low-wattage side-mounted heat mat on a digital thermostat or keep the room at a comfortable room temperature.
  • Shopping at Newberg & Gresham: For enclosures, cork bark, substrates, springtails and feeders at Critter Cabana (Newberg) and Gresham Pet Supply, ask us what we have in store today.

Common Questions (FAQ)

How do I keep my Pumpkin Patch Tarantula warm and humid enough during an Oregon winter?

Keep your spider at a comfortable room temperature with no heat lamp. Keep the water-dish side slightly damp and let the other side dry out on top. Never mist the spider directly. Never put a heat mat underneath the enclosure. Ask us in store for the right setup for your spider.

What size enclosure does a Pumpkin Patch Tarantula need?

An adult Pumpkin Patch Tarantula needs a low, wide enclosure with secure ventilation. Ask us in store for the right size for your spider. For terrestrial tarantulas and scorpions, floor space and deep substrate matter most (keep open fall height low so a fall cannot hurt your spider); for arboreal species, prioritize vertical cork bark tubes and cross-ventilation.

Can I put isopods in a Pumpkin Patch Tarantula bioactive enclosure?

Around molting tarantulas and scorpions, skip big, hungry isopods and stick to springtails, so a soft, newly molted animal is never nibbled.
