The enclosure market has never been better for jumping spider keepers. But more options means more decisions — and some very tempting products that look great but don’t actually suit these animals.
📋 What Jumping Spiders Actually Need #
Before browsing products, understand the non-negotiables. Jumping spiders are arboreal and diurnal — they live high up and hunt in daylight. The enclosure must support both: significant vertical height, strong light penetration, and cross-ventilation that mimics the breezy conditions of their natural habitat.
🏠 Enclosure Types Compared #
| Type | Pros | Cons | Verdict |
|---|---|---|---|
| Arboreal acrylic (purpose-built) | Right dimensions, front-opening, good ventilation | Higher cost | ✅ Best choice |
| Converted deli cup | Cheap, ideal for spiderlings | Outgrown quickly | ✅ Great for juveniles |
| Glass terrarium (front-open) | Excellent visibility, sturdy | Heavier, pricier | ✅ Works well |
| Reptile tub / tub with lid | Cheap and available | Usually poor ventilation | ⚠️ Modify carefully |
| Fish tank (top-open only) | Easy to find | Destroys hammocks, poor airflow | ❌ Avoid |
Many keepers successfully convert food-safe containers. The key requirements: a lockable or snug lid, ventilation holes covered with fine mesh, and front or side access.
📐 Getting the Size Right #
A minimum of 8” wide × 8” deep × 12” tall suits most adult jumping spiders. For Phidippus regius — the largest commonly kept species — aim for 10×10×14” or bigger. When in doubt, size up.
Imagine dividing the enclosure into thirds vertically. Your spider will eat and hunt in the middle third, build their hammock in the top third, and rarely visit the bottom third.
