The Millipede Mystery Box is the most generous way to start or expand a millipede collection — a curated selection of millipedes from our current Millipedes For Sale collection, sent at substantial value uplift compared to buying species individually. The bigger the box, the bigger the uplift — and at the top tier, you receive double the value you pay.

The value proposition is straightforward:

• £25 box — you receive £30 of millipedes (20% bonus value)
• £50 box — you receive £70 of millipedes (40% bonus value)
• £75 box — you receive £120 of millipedes (60% bonus value)
• £100 box — you receive £180 of millipedes (80% bonus value)
• £200 box — you receive £400 of millipedes (100% bonus value — your money doubles)

In exchange for letting us choose the species, you get substantially more millipede for your money than buying individually. The trade-off: this is a mystery box, so you don't pick what's in it — we curate from current stock based on the value tier and what's available at the time of dispatch.

What's in the Box

Every box contains a mix of millipedes selected from our current millipede collection. The species mix is at our discretion, calibrated to the value tier of the box you order. We don't pad boxes with substandard stock or unhealthy specimens — what you receive is the same quality millipedes you'd get buying individually, just at considerably better value because we've chosen the mix.

What to expect at each tier:

• £25 (£30 value): Typically a starter selection of beginner-friendly species — Ivory Millipedes, Burmese Beauty, African Olive (Analocostreptus gregorius), or Hawaiian Glow. Properly suited as a first millipede purchase or a hardy bioactive cleanup crew. Likely 3–5 individuals of one or two species.
• £50 (£70 value): A more substantial mix — typically combining beginner species with one slightly more interesting addition (Thai Rainbow, Olive Millipedes Telodeinopus aoutii, or similar). Likely 6–10 individuals across two or three species.
• £75 (£120 value): A genuinely varied selection — multiple species across different difficulty levels and visual styles. Likely includes a medium-tier intermediate species (Red Fire / Centrobolus, Amber Millipede, or African Giant Chocolate) alongside beginner-friendly stock.
• £100 (£180 value): A serious collection-builder box — multiple species, typically including at least one species from the intermediate or rarer tier. Substantial quantity across the selection.
• £200 (£400 value): Our flagship tier — the box that doubles your money. Expect a properly varied selection that may include rarer stock (Delta Banded, Polydesmus native UK, larger Chocolate adults), substantial quantities, and species across the full collection range. Properly suited to collectors building a comprehensive millipede setup or breeders establishing multiple colonies simultaneously.

Specific species in any given box depend on current stock availability — we can't guarantee any particular species will be included. If you have strong preferences, the individual product listings in the millipedes collection are the right way to purchase those specific species.

Why Buy a Mystery Box

Several genuine reasons make the mystery box worthwhile beyond just the value uplift:

The discovery factor. Some of the best species in any collection are ones the keeper didn't know to look for. The mystery box exposes you to millipedes you might not have selected yourself — including some that may become favourites.

Cost-effective collection building. If you're building toward a substantial millipede setup with multiple species, the value uplift at higher tiers makes the mystery box genuinely the most economical route. A £200 box delivering £400 of millipedes represents a serious cost saving compared to buying the same value individually.

Variety for bioactive setups. Mixed species in bioactive vivariums tend to occupy slightly different ecological niches — some are more surface-active, some burrow deeper, some prefer wetter zones — and a mixed cleanup crew often outperforms a monoculture. The mystery box delivers that variety in one purchase.

Breeder establishment. For keepers planning to breed millipedes commercially or as a hobby, starting with a varied mystery box gives you exposure to multiple species and the chance to identify which thrive best in your specific setup conditions before specialising.

Starter packs for new keepers. The £25 and £50 tiers work well as introductions for keepers who want to try millipede keeping without committing significantly upfront. The hardy beginner species we typically include at these tiers are forgiving of early husbandry mistakes.

Setting Up for Mixed Millipede Species

Because the species mix varies, here's a general-purpose setup that works for most millipedes you might receive. Specific species may benefit from slightly tailored care — read the individual product listings in the millipedes collection for species-specific guidance once you know what arrived.

A plastic storage container or glass vivarium of 30 × 30 cm minimum floor area works for most starter colonies — larger boxes (£75 and above) may need bigger enclosures to accommodate the variety. Drill ventilation holes on opposite sides for cross-ventilation, covered with fine mesh. Most millipedes need moderate ventilation to prevent mould while maintaining humidity.

Provide multiple hides — cork bark flats, decaying wood pieces, and a generous layer of leaf litter on top. Some species climb (Burmese Beauty, Olive Millipedes, Thai Rainbow), so include thick branches and angled cork bark. Other species burrow more than climb (Amber, Ivory, Polydesmus), so deep substrate matters more than vertical decoration.

Keep the enclosure out of direct sunlight and avoid heat mats positioned underneath the substrate — most millipedes burrow to escape unfavourable conditions, and a heat source from below traps them between heat and dry surface.

Substrate — The Critical Component

Substrate isn't just bedding for millipedes — it's their primary food source. Get the substrate right and most millipedes thrive; get it wrong and even hardy species struggle.

A reliable mixed-species substrate recipe:

• 50% decomposed hardwood leaf litter (oak, beech, magnolia — the dietary foundation)
• 20% crumbled rotting hardwood (must be soft enough to crumble between fingers)
• 20% organic topsoil (pesticide-free, fertiliser-free)
• 5% sand or bird grit (small amount for digestion)
• 5% crushed limestone, cuttlebone, or eggshells for calcium

Critically: avoid any pine, cedar, or other coniferous wood or leaves — the resins are toxic to millipedes. We recommend a topsoil and sphagnum-based mix rather than coco coir as the primary component, since coir offers limited nutritional value.

Substrate depth should be at least as deep as the longest millipede's body length — for adult Chocolate or Olive millipedes that's 20+ cm; for smaller Hawaiian Glow or Polydesmus, 8–10 cm is sufficient. Millipedes burrow to moult, and inadequate depth causes moult failures.

Top with a generous layer of whole leaves and pieces of soft rotting wood. Mist as needed to keep the substrate damp but not waterlogged — different species prefer different humidity levels, but a moisture gradient lets the colony self-select.

General Diet for a Mixed Box

Most millipedes are unfussy detritivores. With proper substrate, you've already provided 70–80% of their diet. Supplementary foods that work across most species:

• Fresh vegetables (1–2x weekly): Cucumber, courgette, carrot, sweet potato, squash. Replace within 24–48 hours to prevent mould.
• Fresh fruit (occasionally): Banana, melon, apple, orange — sparingly due to sugar content.
• Protein (1x weekly): Fish flakes, dried shrimp, dried daphnia.
• Calcium (always available): Cuttlebone, crushed limestone, or oyster shell.

Exception: Amber Millipedes (Pelmatojulus ligulatus), if included, largely ignore fresh vegetables and rely almost entirely on white rotten wood and leaf litter. If you receive Ambers, stock heavily on rotting hardwood.

Live Arrival Guarantee

All millipedes — including those in mystery boxes — are covered by our live arrival guarantee. We pack carefully, ship via Royal Mail's next-day-by-1pm service Monday to Thursday, and back every order. Contact us within 24 hours of delivery if there's a problem and we'll sort it.

Standard PostPods orders include a 20% overcount on top of stated quantities, providing additional value buffer.

Realistic Expectations

You don't get to pick the species. That's the trade-off for the value uplift — we choose the mix from current stock. If you have specific species in mind, the individual product listings are the right route, not the mystery box.

Stock availability shapes what you receive. The species mix in any given box depends on what's in stock at the time of dispatch. Boxes sent in different months may contain quite different species selections. If a particular species is sold out across our suppliers, it won't be in any box that month — regardless of tier.

The value uplift is real, not a sales gimmick. The pricing tier of each box reflects genuine retail value of the millipedes inside — not inflated retail prices used to make the bonus look bigger than it is. The £400 box contains £400 of millipedes at our standard individual-listing prices.

Pair with springtails. A springtail culture is properly important for any mixed millipede setup, particularly at the high-humidity end of the species range. Springtails handle mould and microbial growth at a scale millipedes can't manage.

Setup costs are separate. The mystery box covers the livestock — substrate, enclosure, leaf litter, calcium sources, and other setup items are separate purchases. The Drygoods & Accessories collection covers the supplementary equipment side.

Read the individual species listings once you know what arrived. The millipede collection has detailed care information for every species we stock — well worth checking once you've opened your box and identified what's inside.

Compare with the isopod equivalent. If you're considering a mystery box approach for isopods too, the Isopod Mystery Box operates on a similar value-uplift basis with our isopod range. Combining both gives you a properly comprehensive starter for a bioactive setup.
