When temperatures drop, your worms still need to stay cosy, moist, and busy.
The Extra-Thick Wiggly Moisture Mat for Can-O-Worms is made from dense natural hemp fibre (~900 g/m² equivalent) — around 50 % heavier than our standard mat — giving better insulation, longer life, and extra moisture retention.

It’s the same breathable, compostable hemp you already love, but with added warmth for winter or outdoor wormeries. Designed to fit the Can-O-Worms tray perfectly, it keeps conditions stable, reduces odours, blocks fruit flies, and encourages your worms to keep composting right through the coldest months.

Key Benefits

🔥 Winter Warmth: Thicker fibre keeps heat where it belongs — inside your wormery.
💧 Superior Moisture Retention: Denser weave means longer humidity hold and fewer dry patches.
🪰 Fly Barrier: Naturally deters fruit flies from reaching fresh waste.
🌿 Reduced Odour: Creates a breathable, stable compost surface.
♻️ Long-Lasting & Compostable: Typically lasts 4–6 months; breaks down safely afterwards.
🌑 Light Shield: Keeps worms near the surface, feeding and multiplying.

Worms are surface feeders — they need access to fresh waste near the top of the bin.

Without a proper cover:

  • the surface dries out
  • heat escapes
  • flies invade
  • decomposition slows

A moisture mat creates a damp “ceiling” that traps moisture, stabilises temperature, and keeps worms active where they should be.

Replace regularly for best results

Moisture mats gradually break down over time — and worms will even eat them.

  • Typical lifespan: 2–4 months+ depending on use

Replacing them regularly:

  • keeps conditions stable
  • prevents problems
  • maintains performance

Standard mats

  • Ideal for everyday use
  • Lighter and easier to replace
  • Best for most indoor systems

Heavyweight mats

  • Thicker (~900 g/m²)
  • Better insulation and moisture retention
  • Longer lasting
  • Ideal for winter or outdoor setups

If your wormery, compost system — or even garden bed — needs a made-to-measure solution, the Wiggly Moisture Mat by the Metre is your most flexible option.

Supplied in a continuous 1m wide roll of hemp fibre, it delivers all the benefits of our worm blankets:

  • moisture retention
  • odour control
  • insulation
  • pest protection

🌿 Also perfect for the garden

Use it as:

  • mulch
  • weed barrier
  • moisture retention layer

It locks in water, suppresses weeds, and slowly breaks down to improve soil.

Worms and plants both need:

  • 💧 Moisture → worms breathe through skin
  • 🌑 Darkness → encourages surface feeding
  • 🌬️ Stability → improves composting speed
  • 🔥 Warmth → supports microbial activity

Get these right — and everything works better.

🪱 HOW TO USE

  1. Place directly over your waste layer, beneath the lid
  2. Feed underneath it
  3. Keep it covering fresh waste
  4. Check moisture weekly
  5. Replace every 2–3 months

💡 WIGGLY TIPS

  • Add Rock Dust or Lime Mix monthly
  • Fluff compost occasionally for airflow
  • Use heavyweight mats in winter
  • Switch back to standard in summer

♻️ SUSTAINABILITY

  • 100% hemp fibre
  • Fully biodegradable
  • Zero plastic

When it’s done — compost it.

What our customers say

Brilliant live worms and great service! I ordered a batch of live composting worms for my new wormery, and they arrived in perfect condition — lively, healthy, and ready to get to work straight away. The packaging was eco-friendly, and the team even included a little guide on how to settle them in. My kitchen scraps are disappearing fast, and I’ve already started harvesting my first bit of worm compost. Couldn’t be happier!

Fantastic bokashi composting advice As a complete beginner to bokashi composting, I really appreciated how helpful the team were. They answered all my questions quickly and gave me simple, clear instructions to get started. The bokashi bran is top quality and smells fresh and pleasant. After just a few weeks, I’ve turned my kitchen waste into brilliant compost-ready material with no odour or mess. Highly recommended!
James T.
Top-notch British birdseed mix The British birdseed from Wigglys is superb. It attracts a lovely variety of garden birds — robins, finches, and even a pair of goldfinches have started visiting regularly. You can tell it’s a quality mix with no fillers or dust. Delivery was quick, and everything was packaged sustainably. It’s become my go-to source for bird feed!
