Bug Hotels for Biodiversity: Three DIY Insect Homes for Your Homestead

Look for small, neat exit holes and sealed cavities across the different nesting materials. In bamboo bundles you might see mud caps from mason bees, while in twig and bark sections you’ll spot hollow stems with chewed ends indicating solitary wasps or other bees. Leaf-litter layers that appear disturbed often signal lacewings or earwigs have taken up residence. A few minutes’ periodic observation in spring and summer will reveal a lively micro-ecosystem at work!

Carry out major maintenance in late autumn once most species have emerged or entered hibernation. Remove and discard any tubes, stems or insulation showing mould, frass or pest infestation, then store reusable pieces in a cool, dry shed over winter. Every two years, refresh bedding layers such as straw, pine needles or leaf litter, to maintain cleanliness and encourage new occupants without risking mite or fungal build-up.

Fit a fine-mesh guard a few centimetres in front of nesting cavities to deter birds and small mammals while still allowing insects clear access. Ensure the roof overhangs sufficiently to keep rain off and elevate the hotel 30–50 mm above the mounting surface to prevent damp. Position it in a sheltered spot, southeast-facing is ideal and avoid nearby foot traffic to minimise disturbance, then inspect annually for damage or decay.
