How to Site a Solitary Bee Hotel So It Actually Gets Used

Start with the unused-hotel problem

A neighbour’s bee hotel hung on a shaded north wall for two summers and stayed empty. The cause was not bad luck: solitary bees need warmth and a clear flight path, and a cold, damp wall gives them neither. The fix is to treat siting as the first job, not an afterthought. Before buying or building another box, walk the garden at midday and note which walls catch morning sun and stay dry.

Choose the wall before the box

South- and southeast-facing walls are the reliable starting point because they warm early and dry quickly. A wall under deep eaves can stay too dry and cracked; a wall beside a downpipe can stay damp. The solution is a spot with morning sun, shelter from prevailing wind, and no dripping gutter above. Mount the hotel at eye level or slightly higher, roughly 1–1.5 metres from the ground, so you can inspect it without a ladder and so it sits above most ground damp. Keep it at least 30 cm clear of dense shrubs.

Match the nesting material to local bees

Not every bee uses every tube. Mason bees favour hollow stems and drilled wood; leafcutter bees line cavities with leaf pieces; some bumblebees nest in ground cavities and ignore bee hotels entirely. The cause of many failed hotels is a mixed box with splintered holes or tubes that are too wide. The solution is to use smooth tunnels 6–10 mm across, closed at the back, and to avoid plastic straws that trap condensation. The wildzy placement notes are a useful cross-check for cavity-nesting species: face the openings slightly downward or keep them level so rain does not run in. Do not add honeybee frames; a solitary bee hotel is not a hive.

Provide mud, leaves and a water edge nearby

A hotel without building materials is a bedroom without bedding. Mason bees need damp, clay-rich soil for sealing walls; leafcutters need soft leaves and petals. If the garden is mulched everywhere, the cause is clear: no exposed mud. The solution is a small, undisturbed patch of bare earth kept slightly damp, plus a shallow water dish with stones for drinking. Place these within 20–30 metres of the hotel. Avoid insecticides on nearby flowers, especially while bees are provisioning nests.

Inspect, clean and replace without drama

An occupied hotel should be left alone until autumn. The problem comes when people clean too early and destroy developing larvae. The cause is treating the box like a birdhouse; the solution is to wait until the tubes are sealed and activity stops. In late autumn, move removable tubes into a cool, dry shed or unheated garage, then replace them in spring. If the hotel has fixed tunnels, clean the front with a dry brush and replace worn sections rather than scrubbing inside. A simple record of what was used each year tells you more than a new design.
