Lewtemi Mason Bee Paper Tubes, 360-Pack 6-inch 8mm Kraft Nesting Inserts — Replaceable Sanitary Refills

Lewtemi 360 mason bee paper tubes are a bulk refill of 6-inch, 8mm inner-diameter cardboard nesting inserts designed to provide a durable, recyclable home for solitary mason bees.

These replaceable paper tubes simplify mason bee management by offering a ready supply of sanitary, easy-to-handle nesting cavities that fit many standard bee houses. Made from sturdy Kraft-style paper, each tube is about 15 cm (6 inches) long with an inner diameter near 0.31 inches (8 mm). The pack of 360 gives gardeners, beekeepers, and conservation groups a large, economical stock of nesting material that can be trimmed to size and replaced seasonally to maintain healthy nesting conditions.

How do these paper tubes support mason bee nesting?

The tubes mimic the narrow cavities mason bees prefer for laying eggs, giving females a safe, ventilated chamber to provision with pollen and nectar. Their smooth interior and consistent diameter encourages occupation and reduces the chance of brood damage. Because they're replaceable, you can remove used tubes to limit parasites and disease between seasons.

• 8 mm inner diameter tailored for many Osmia species
• 6-inch length provides adequate depth for multi-cell nesting
• Smooth, burr-free edges reduce injury to bees
• Replaceable design makes hygiene management straightforward

Will these tubes withstand outdoor conditions?

Constructed from reinforced Kraft-style paper, the tubes resist moderate pressure and handle normal outdoor exposure when installed inside a protective bee house or sheltered mounting. They’re intended for use inside a drilled-block or tubular bee hotel rather than exposed to direct driving rain. If you need longer-term durability, install them in a weatherproof frame or under eaves to extend service life.

• Durable paper resists light moisture and external pressure
• Best performance when placed inside a sheltered bee house
• Can be cut to fit different housings or replacement slots
• Recyclable material for easy seasonal disposal

How do I install, trim, and maintain these nesting inserts?

Installation is straightforward: slide each tube into the corresponding slot of your bee house or a compatible frame, ensuring the open end faces outward. Trim to shorter lengths if your housing or local bee species prefer less depth. At season’s end, remove used tubes and replace with fresh ones to reduce pests and encourage healthy next-season emergence.

• Cut tubes with a clean blade to desired length
• Insert open ends facing outward, snug but not compressed
• Replace used tubes annually to control parasites
• Store unused tubes dry and flat to preserve shape

What size and quantity should I expect in this pack?

This bulk refill contains 360 individual paper tubes, each roughly 15 cm (6 inches) long and about 8 mm (0.31 inches) in inner diameter — a common size for many mason bee species. The high quantity suits community gardens, farms, educational programs, or any gardener who wants a long-term supply without frequent reordering.

• 360 tubes per package — ample supply for large setups
• Approximately 15 cm length, 8 mm inner diameter
• Natural brown Kraft paper color blends with outdoor decor
• Recyclable and non-toxic construction
