Looks how to spot one
Personality what they are like
Generally docile and can be handled with care, but they may pinch with their pedipalps or spray acetic acid if they feel threatened. They are not aggressive and prefer to flee or use defensive displays. Handling should be gentle and close to the ground to avoid falls.51
Daily activity how busy a day looks
Nocturnal and fairly active at night. They need floor space to explore and a deep substrate for burrowing. They do not require a heat lamp if kept at normal room temperature.54
Grooming and care the hands-on bits
Keep the substrate slightly moist by misting half of it daily. Provide hiding places like cork bark and leaves. A shallow water dish is recommended. Clean the enclosure regularly to prevent mould. Handle rarely and with care.5
Home where they are happiest
A 5-gallon aquarium with a screen lid is suitable for an adult. Use at least 5 inches of substrate that holds burrows, such as coconut fibre mixed with sphagnum and peat moss. Keep the substrate slightly moist. Provide branches and hiding spots. Room temperature is fine; avoid heat mats on the bottom.5
Food basics what goes in the bowl
Insectivorous. Feed juveniles small crickets or roaches several times a week. Adults can take 3-4 medium crickets every 3-4 weeks. They may fast for months, which is normal. Always provide live prey.54
Company who they like around
Solitary. They must be kept alone as they are predators and will fight with other vinegaroons. They are not venomous, but they can spray acetic acid, which can irritate eyes and skin. Handle with care and keep away from small children.51
The story where it all began
The giant vinegaroon has been known to science since 1835 and is found across the southern United States and Mexico. It has been kept as an exotic pet for many years, though it is not as common as tarantulas. Captive-bred individuals are preferred over wild-caught ones for sustainability and health.65
Recognised by the official bits
- Texas A&M AgriLife Extension
- Recognised as a non-poisonous arachnid that can spray acetic acid from glands at the base of its tail when disturbed.2

Owner questions the things everyone asks
How often should I feed my Vinegaroon?
Juveniles need small live crickets several times a week, while adults only need 3-4 medium crickets every 3-4 weeks. They may fast for months, which is normal. Furry Diary's starting plan notes that feeding depends on species, size and moult stage.54 Furry Diary plan
What does a Vinegaroon eat, and what should it never eat?
They eat live insects like crickets and roaches. Never feed dead prey or non-insect food; always provide live prey.54
How much space does a Vinegaroon need?
An adult needs a 5-gallon aquarium with a screen lid and at least 5 inches of deep substrate for burrowing. This gives them floor space to explore.5
What temperature, light or water does a Vinegaroon need?
Normal room temperature is fine; no heat lamp needed. Provide a shallow water dish and keep the substrate slightly moist by misting. Avoid heat mats on the bottom.54
How often should I clean a Vinegaroon's home?
Spot clean leftover food weekly and change the entire substrate every 6 months. Regular cleaning prevents mould and keeps your vinegaroon healthy. Furry Diary plan
Can a Vinegaroon live with others?
No, they are solitary and must be kept alone. They are predators and will fight with other vinegaroons.51
Can I handle a Vinegaroon?
Yes, with gentle care. They are docile but may pinch or spray acetic acid if threatened. Always handle close to the ground to avoid falls, and keep away from small children.51
