Rehousing Tarantulas: A Complete Guide

Safe & Stress-Free Transfers for All Experience Levels

Introduction

Whether you’re a beginner tarantula keeper or an experienced hobbyist, rehousing tarantulas is an unavoidable part of the journey. Tarantulas outgrow their enclosures, require upgrades, or need to be moved due to mold, pests, or substrate issues. While it may sound intimidating, rehousing doesn’t have to be dangerous — as long as it’s done carefully, calmly, and correctly.

This guide will walk you through how to safely rehouse tarantulas of all sizes and temperaments, with practical tips, equipment lists, and best practices for avoiding stress (for you and your spider!).

When Should You Rehouse a Tarantula?

Knowing when to rehouse is key to ensuring your tarantula’s health and comfort. You should consider rehousing if:

  • 🕷️ The tarantula has outgrown its current enclosure
  • 🌱 You’re upgrading from a sling enclosure to a juvenile or adult home
  • 🦗 Uneaten prey, mold, or mites have contaminated the substrate
  • 🛠️ The current enclosure is difficult to maintain or unsafe
  • 💧 Poor ventilation is causing humidity issues
  • 🎨 You’re moving the tarantula into a permanent display setup

Equipment You’ll Need

Before starting, gather the following:

✅ Catch cup (clear plastic cup with soft edges)
✅ Long tongs or feeding tweezers
✅ Soft paintbrush (for gentle coaxing)
✅ New enclosure (pre-set up and escape-proof)
✅ Flat work surface (table, floor, or inside a large bin)
✅ Gloves and long sleeves (optional, especially for defensive species)
✅ Duct tape or paper (to seal air holes temporarily if needed)
✅ Calm, quiet environment — no loud noises or distractions

General Rehousing Steps (All Species)

These basic steps work for most tarantulas, whether they’re slings or adults, docile or defensive.

1. Prepare the New Enclosure

  • Ensure the new setup is fully ready — substrate, hide, water dish, and ventilation in place.
  • For arboreals, ensure vertical space and climbing decor.
  • For terrestrials and fossorials, include enough depth for burrowing.

2. Choose the Right Time

  • Avoid rehousing during pre-molt or immediately after a molt.
  • Choose a time when the tarantula is less active (usually daytime).
  • Give yourself plenty of time — don’t rush the process.

3. Transfer with Patience

  • Use a paintbrush or tongs to gently coax the tarantula into a catch cup.
  • Once secured, place the cup into the new enclosure and gently tip it to release the spider.
  • Close the enclosure immediately and ensure it’s locked securely.

Rehousing by Size & Type

🕷️ Rehousing Slings (Spiderlings)

  • Use soft tools and small deli cups or dram vials.
  • Tiny slings are fragile — avoid forcing movement.
  • Move them to slightly larger containers with good ventilation and shallow substrate.
  • Watch for sudden jumps or webbing escapes!

🕷️ Juveniles

  • Fast but often manageable.
  • Upgrade to enclosures 3–5x leg span in width and height.
  • Be prepared for a quick bolt — have your catch cup ready.

🕷️ Adults

  • More mass = more risk if dropped or startled.
  • Use larger catch cups and extra caution.
  • Provide plenty of anchor points in the new enclosure so the spider can settle.

Rehousing Docile vs Defensive Tarantulas

✅ Docile Species (e.g., Brachypelma, Grammostola)

  • Move slowly and confidently.
  • Often tolerate coaxing or gentle touch.
  • Low bite risk, but still avoid handling.

⚠️ Defensive or Fast Species (e.g., Poecilotheria, Haplopelma)

  • Use long tongs and keep hands out of the enclosure.
  • Expect fast movement or defensive postures.
  • Rehouse inside a large plastic bin or bathtub to prevent escapes.
  • NEVER attempt to handle — even calm individuals can bolt suddenly.

Safety Tips & Tricks

💡 Always Plan Ahead
Visualize every step. Know where the spider is likely to move and how you’ll respond.

🛑 Stay Calm
Sudden movements can cause your tarantula to bolt. Breathe and move slowly.

🔐 Secure All Openings
Use tape or paper to cover any ventilation holes during transfer if needed.

🚫 Never Use Bare Hands
Even docile species can bite or bolt — always use tools.

👀 Watch for Pre-Molt Behavior
Dull color, reduced appetite, and lethargy are signs not to rehouse just yet.

📸 Document Your Setup
Take a quick photo of your finished enclosure for reference later.

What to Do If Your Tarantula Escapes

If your tarantula bolts during rehousing:

  1. Stay calm — no yelling, chasing, or sudden grabs.
  2. Gently contain it with a catch cup or soft barrier.
  3. Dim the lights — tarantulas tend to freeze in the dark.
  4. Search corners, under furniture, and behind decor.
  5. Never try to pick it up with your hands.

Rehousing Checklist ✅

  • New enclosure fully set up
  • Catch cup and tools ready
  • Safe, sealed environment
  • Calm demeanor
  • No distractions or pets nearby
  • Backup container in case of escape

Final Thoughts

Rehousing doesn’t have to be a high-stress event. With proper preparation, the right tools, and a respectful approach, you can make the process smooth and safe — for both you and your tarantula.

Whether you’re moving a tiny sling or a bold Old World adult, every rehouse builds your experience and confidence in the hobby.

Remember: Patience is the most important tool in your kit.
