Description
Give your cultures and micro-fauna systems a clean, dependable fibrous media with Big Bites Excelsior. This 100 g pack delivers aspen wood wool that’s perfect for live-food rearing, micro-invert enclosures, and layered substrate systems.
-
Super fine, fibrous wood wool — excelsior offers a network of tiny fibres that encourage airflow, drainage and movement in substrate or culture containers.
-
Ideal for insect / microfauna culture — Use as bedding or layering media for springtails, fruit-fly cultures, bean weevils, etc., to promote healthy movement and reduce compacting. (General husbandry guides list aspen excelsior as suitable in insect culture to provide surface area and refuge for live food)
-
Supports substrate health — When mixed into substrate or used as a top-layer, wood fibres help maintain loose structure, reduce compaction and improve decomposition / detritus turnover.
-
Ready for hobby use — Clean, natural wood (aspen), minimal processing, no added chemicals or heavy residues. Clean-out friendly.
-
Compact & low-waste pack — At 100 g it’s sized for smaller builds, starter setups, culture trays, or hobbyist add-ons.
How to Use:
-
For insect culture: add a layer of excelsior in culture containers under or mixed with substrate so that small feeders can crawl and hide.
-
For microfauna bins: mix approx 10-20% by volume into your litter or leaf-layer to impart structure and slow compaction.
-
For terrariums: use as a light top-drape, small filler under décor, or in microfauna/clean-up crew refugia spots.
-
Inspect regularly for moisture/humidity balance. Remove or refresh fibres if they saturate or begin to rot.
Why It Matters:
Many insect cultures and microfauna systems fail because either the substrate becomes too compacted, moisture stagnates, or the live-food lack refuge/drafting zones. By using a fibrous material like excelsior, you give life a chance to move, hide, reproduce and thus become self-sustaining. Particularly for your “Grow Your Own feeders” line and clean-up crew cultures, this is a handy media.
