How to Set Up a Moult-Safe Tarantula Enclosure

Posted: May 26, 2025

Whether you’re new to the hobby or a long-time keeper, ensuring your tarantula’s enclosure is moult-safe can mean the difference between a routine shed and a tragedy.

1. Start with the Right Substrate

Use moisture-retaining substrate like coco fibre or topsoil, depending on your species. It should hold humidity but not be soggy. A dry enclosure can lead to stuck moults.

2. Provide Vertical or Horizontal Space

Arboreal species need vertical space to hang and moult, while terrestrials need room to stretch. Make sure enclosure height is appropriate for the species — too tall for a terrestrial can lead to injury.

3. Hide and Retreat Areas

Offer cork bark or a cave hide to help your tarantula feel secure before and after moulting. Stress from exposure can increase the risk of complications.

4. Maintain Humidity Without Overdoing It

Aim for a balance — not too dry, not too wet. Consider misting part of the enclosure or adding moss to keep humidity stable without creating swampy conditions.

5. Don’t Skip the Water Dish

Even tiny slings need access to moisture. A shallow bottle cap or small dish with fresh water can support hydration during a moult, especially when appetite disappears.

And Don't Forget…

While enclosure setup is key, internal support also matters. That’s where MoultMend fits in — giving your tarantula the hydration and post-moult recovery aid they deserve.
