Building a bug hotel from recycled household materials is one of the simplest ways to support garden wildlife. Conservation charities recommend using untreated timber, bamboo, and fallen natural items to create layered shelter for beneficial insects like solitary bees and ladybirds. This guide draws on the latest advice from the Woodland Trust, RSPB, and other authoritative sources to help you build a safe, effective bug hotel in an afternoon.

How we researched this

Last checked: 2026-07-31.

Sources reviewed: Official conservation charity websites, government horticulture body guides, independent gardening blogs, and educational museum resources.

We did not build or test a bug hotel ourselves, nor did we conduct original entomology research. All recommendations are drawn from published guidance.

Key insights from the research

  • Drill depth consensus: 10 cm – recommended by Bord Bia and others for drilled logs.
  • Material diversity: At least 7 natural materials recommended across the top 5 guides we analysed.
  • Sturdy base advice: Bricks and level ground emphasised by the RSPB and Woodland Trust.

What you need to know before you start

1 Materials
  • Use untreated timber and natural fillers such as bamboo, bark, twigs, moss, and pine cones. Avoid treated wood or composite boards. (Woodland Trust)
2 Dimensions
  • Drill holes 10 cm deep with varying diameters. For solitary bees, hollow stems should have internal diameters of 1/16 to 1/2 inch (1.5–13 mm) and lengths of 5–8 inches (12–20 cm). (Sierra Club)
3 Placement
  • Place the hotel on a firm, level base – bricks or a wooden pallet – and avoid direct contact with damp soil. Maximum recommended height: 1 m (about 3 ft). (RSPB)
4 Safety
  • Only use fallen natural materials – never pick live plants. Recycle household items like cardboard tubes, plastic bottles, and wooden pallets to keep the project low-cost and waste-free. (WWF UK)

What can I use to make a bug hotel?

Most bug hotels start with a simple recycled container – a flowerpot, yoghurt pot, mug, drinks carton, shoebox, or cut plastic bottle – packed tightly with natural materials. The Woodland Trust recommends filling the frame with hollow sticks, bamboo canes, twigs, bark, straw, dry leaves, moss, pine cones, and dead wood.

Natural materials vs recycled materials

Natural and recycled materials work together. The RSPB suggests using old wooden pallets for large garden-scale hotels, while the WWF UK advises using household waste such as cardboard tubes and plastic bottles. Reusing items keeps costs low and reduces landfill. Merthyr Tydfil County Borough Council also promotes pallet-and-bottle designs.

Drilling holes in untreated timber

For drilled logs, use untreated wood only. Treated or composite wood can contain chemicals harmful to insects. Drill holes about 10 cm deep with varying diameters to attract different species. The Sierra Club notes that solitary bees prefer tubes with internal diameters of 1/16 to 1/2 inch and lengths of 5–8 inches.

Tip: Pack materials tightly so they don’t fall out when the hotel is moved. Several garden guides emphasise that firm packing creates stable crevices while still leaving usable gaps.

The bottom line: Use what you have at home – untreated wood, plastic bottles, bamboo – and fill tightly with a mix of natural items.

How high off the ground should a bug hotel be?

Placement height depends on the hotel’s size and target insects. The RSPB advises raising large pallet hotels no higher than 1 m (about 3 ft). For smaller hanging hotels, the Wildfowl & Wetlands Trust recommends suspending them about 1 m above the ground at the base of a tree or bush.

Ground-level placement on bricks

A sturdy base is essential. The Woodland Trust and RSPB both recommend placing the hotel on bricks or a wooden pallet to keep it off damp soil. This prevents rot and extends the structure’s life.

Benefits of elevation

Elevating the hotel even a few inches helps protect it from ground moisture and predators. Some garden bloggers suggest mounting permanent wooden hotels 3–5 ft off the ground with a protective roof, though this is less common in official charity guidance.

Note: If you live in a very wet area, consider adding a roof made of untreated wood or a recycled plastic lid to keep the fillings dry.

The trade-off: Higher placement may limit access for ground-dwelling beetles, while ground-level hotels risk dampness. A height of 1 m works well for most gardens.

What size hole for a bug hotel?

Drill hole dimensions are critical for attracting the right insects. The Sierra Club provides precise guidance: for solitary bees, use hollow stems with internal diameters of 1/16 to 1/2 inch (1.5–13 mm) and lengths of 5–8 inches (12–20 cm). For general-purpose drilled logs, conservation bodies recommend 10 cm deep holes of varying diameters.

Drill bit diameters

Use a range of drill bits, from 2 mm up to 10 mm, to create cavities for different insect sizes. The Natural History Museum of Los Angeles County suggests using shoebox or cardboard-based hotels with simple holes punched into cardboard tubes.

Hole depth recommendations

Depth matters: 10 cm is the consensus across multiple guides. Deeper holes provide better insulation and protection from predators. The RSPCA’s family-friendly instructions also recommend this depth for small container hotels.

What this means: Vary diameters and keep depth around 10 cm to maximise the range of insect visitors.

How to Make a Bug Hotel

This step-by-step method combines the RSPB’s pallet design with the Woodland Trust’s material guidance. It works for gardens of any size and can be adapted for children.

Building the frame

  1. Choose a sturdy base: a wooden pallet, a stack of bricks, or a large plastic bottle laid on its side.
  2. If using a pallet, place it on four bricks – one at each corner – to lift it off the ground.
  3. For a frame, construct a simple wooden box using untreated timber. Garden Therapy provides a cedar plan: a 12-inch high back panel, 5.5-inch square top and bottom, and 4.75-inch side panels.

Filling the layers

  1. Fill the frame with a mix of materials: bamboo canes, hollow stems, twigs, bark, dry leaves, moss, pine cones, and dead wood. Pack each layer tightly.
  2. Insert cardboard tubes or toilet roll tubes into the gaps for extra structure. The WWT shows how to use a drinks carton with toilet roll tubes for an indoor-grade kids’ version.
  3. For drilled logs, drill holes 10 cm deep with varying diameters and place them in the hotel with the open ends facing outward.

Positioning the hotel

  1. Place the completed hotel in a sheltered, dry spot – ideally facing south or southeast to catch morning sun. Sheltered areas near hedges or trees work well.
  2. Ensure the hotel is on a firm, level base. If hanging, use strong string and suspend it about 1 m above ground.
  3. Add a roof (a spare piece of untreated wood or a plastic lid) to keep the interior dry.

“You can make an inviting bug house using materials recycled from your home or garden, along with natural items that replicate wild habitats.”

Best bug hotel designs for different audiences

For kids

Use a small container like a yoghurt pot, mug, or cut plastic bottle. The RSPCA recommends filling it tightly with bamboo or hollow stems and laying it on its side in a sheltered spot. No tools required – just gather materials and pack. The WWF UK also has a simple shoebox design that children can decorate.

For families

Build a drinks carton hotel together. Cut a rectangular opening in one side, insert toilet roll tubes, and pack with moss, leaves, and pine cones. The Wildfowl & Wetlands Trust shows this method in a video tutorial. It’s quick, safe, and can be hung indoors or outdoors.

For general gardeners

Construct a large pallet hotel using bricks, wooden pallets, and a variety of natural fillers. The RSPB’s plan is the most thorough: stack pallets, fill gaps with plastic bottles stuffed with bamboo and leaves, and add a roof. This design attracts a wide range of species and lasts for years with minimal maintenance.

“Old wooden pallets are perfect for a large hotel as they’re sturdy and come with ready-made gaps.”

Frequently asked questions

How to make a ladybug hotel?

Ladybugs (ladybirds) prefer small, dry crevices. Use a small container such as a yoghurt pot or a short plastic bottle, fill it tightly with bamboo canes, twigs, and dry leaves, and place it on its side in a sheltered, sunny spot. The RSPCA provides a similar design for general insects that works well for ladybugs.

Make a bug hotel from recycled materials?

Yes – most charity guides highlight recycling. The Woodland Trust, WWF UK, and Merthyr Tydfil Council all recommend using plastic bottles, cardboard tubes, shoeboxes, and wooden pallets. Avoid treated wood, and always use fallen natural materials.

How to make a bug hotel out of cardboard?

Cut a rectangular opening in one side of a drinks carton or shoebox. Insert toilet roll tubes for structure, then pack tightly with moss, dry leaves, sticks, and pine cones. The WWT demonstrates this design in a family-friendly video. Hang it in a dry, sheltered spot.

How to make a bug hotel for kids?

Use a small container like a mug, yoghurt pot, or cut plastic bottle. Fill with bamboo or hollow stems and natural materials. The RSPCA recommends packing tightly so the fillings stay in place. No sharp tools are needed – just supervision for younger children. The WWF UK also has a no-drill shoebox version.

How to build a simple bug hotel?

The simplest design: take a plastic bottle, cut it in half, fill the bottom half with bamboo canes, twigs, and leaves, then tie the top half back on (or leave it open). Place it on its side on bricks in a sheltered garden spot. The Woodland Trust describes this as a quick one-hour project.

What makes a good bug hotel?

A good bug hotel uses untreated wood, offers a variety of cavity sizes (2–10 mm diameter, 10 cm deep), and is placed on a firm, level base off the ground. It should be packed tightly to prevent materials from shifting, and kept dry with a roof or sheltered location. The RSPB and Woodland Trust agree on these core principles.
