Orange Baboon Tarantula Feeding Guide — Pterinochilus murinus

Feed Orange Baboon Tarantulas according to size, appetite and condition rather than a fixed weekly schedule. Pterinochilus murinus is a fast-growing terrestrial species, so small juveniles often eat more regularly than adults.

How often should you feed?

There is no single feeding interval that suits every Pterinochilus murinus. A small sling may take modest meals quite regularly, while a large adult can go much longer between feeds.

If an Orange Baboon Tarantula has eaten recently and the abdomen already looks well filled, wait before offering more. One refused meal is rarely important on its own.

Choosing prey

Offer Pterinochilus murinus established feeder insects that the spider can overpower without a long struggle. Crickets, locusts and roaches are all commonly used where they are legal and appropriately sized.

For very small Orange Baboon Tarantulas, use smaller prey or a suitable pre-killed feeder if that makes feeding safer. Increase prey size gradually as the spider grows.

Slings and juveniles

Young Orange Baboon Tarantulas generally moult more often than adults, so they usually eat smaller meals more frequently. Keep portions sensible and remove leftovers from the Pterinochilus murinus enclosure.

A juvenile Orange Baboon Tarantula may stop eating before a moult. If the spider is hiding more, closing its retreat or ignoring prey it would normally take, remove the feeder and give it time.

Adults

Adult Pterinochilus murinus do not need to be kept permanently full of food. As the spider approaches an adult size of about 13–15 cm (5–6 in), feeding can usually be spaced farther apart than during rapid juvenile growth.

Use the abdomen as a rough guide for Orange Baboon Tarantulas. If it is already very large, another heavy meal is unnecessary.

Food refusal and premoult

Food refusal in Pterinochilus murinus can happen for normal reasons including premoult, recent rehousing, maturity or a period of lower appetite. Check water, temperature and the enclosure before assuming there is a problem.

If premoult looks likely in an Orange Baboon Tarantula, remove live prey and keep fresh water available. Do not keep offering new feeders every day.

Feeding after a moult

After Pterinochilus murinus moults, wait until the new exoskeleton has hardened and the fangs have darkened before feeding again. Small slings recover faster than large adults.

When an Orange Baboon Tarantula is ready to eat again, offer a modest first meal rather than several feeders at once.

Water, leftovers and safe feeding

Keep fresh water available to Pterinochilus murinus even when the spider is feeding well. Remove discarded prey remains before they sit in damp substrate and begin to spoil.

There is no need to hand-feed Orange Baboon Tarantulas. Place prey into the enclosure from a sensible distance, use tongs for removing leftovers when needed and keep your hands out of the spider's path.
