About
The Halloween Patch ("Theraphosidae sp. Columbia" - vendor spelling of Colombia; even the GENUS is unknown) - a total mystery species whose orange-and-black sling patterning earned the trade name, offered at £125 per centimetre-long sling: the most expensive sling on the whole UK market. Vendor stats: docile, cool-tolerant, no size data. Every parameter in this guide is a provisional placeholder until the animal grows and the trade learns - a genuine frontier purchase.

Is my Halloween Patch Tarantula dying or moulting?
Pre-moult signs to look for
Refusing food for weeks is normal before a moult - a healthy Halloween Patch Tarantula fasting is almost never an emergency in itself. Watch for slowing down and spending more time in the hide, laying a thick moult mat of web on the floor. New World species like this one often show a bald spot on the abdomen that darkens to near-black as the new skin underneath readies - a darkening bald patch is a reliable countdown, not a disease.
On its back is MOULTING, not dying
A Halloween Patch Tarantula lying upside down or on its side with legs curled inwards is almost certainly mid-moult. Do not touch it, do not right it, do not mist it - just remove any live prey (crickets can kill a defenceless moulter) and leave the room.
How long between moults?
For this species, expect a moult roughly every 25-50 days for spiderlings, every 60-100 days for juveniles, and every 140-220 days for sub-adults, with adult females moulting around every 10 months (up to 14.7 months at the extreme). Males never moult again after their ultimate (mature) moult.
After the moult: fang hardening time
The new exoskeleton stays soft, with fangs that cannot grip, for roughly 7 days in this species. Offer no food and no handling for about 7 days - feeding too early is how fresh moulters get injured. The shed exuvium is also the best sexing tool there is - see our tarantula sexing guide for what to look for.
Genuinely worried about behaviour that is not moulting? Our "Is my T okay?" triage tool walks the danger signs one by one.
What ongoing care does a Halloween Patch Tarantula need?
🪞 Moulting
Signs: refuses food, abdomen darkens, becomes sluggish. Do not disturb; keep water available; wait for black hard fangs before feeding. Adult intervals apply to mature FEMALES - a mature male never moults again.
🧹 Cleaning
Daily: check the water dish. Weekly: remove boluses and spot-clean.
✋ Handling
Docile per the vendor - but handle rarely given the unknowns.
