Insect Houses: Giving Solitary Bees And Beetles Shelter

Shelter matters as much as food. A quiet, shaded corner away from foot traffic and pets, ideally backed onto a hedge or shrub border, is the right spot for a dedicated shelter. Gardeners setting one up for the first time often start by browsing hedgehog houses to see the range of designs suited to different garden sizes.

Timing across the season is worth planning for deliberately, since gaps in flowering leave pollinators with nothing to forage on for weeks at a stretch. Leaving seed heads standing rather than cutting borders back in autumn also gives finches and other seed-eating birds a natural food source right through the colder months.

Not every beneficial garden insect lives in a hive or a colony. Many UK bee species are solitary, nesting alone or in loose aggregations, and insects such as lacewings and ladybirds shelter individually or in small clusters, particularly over winter. An insect house gives these species something a tidy garden often lacks: safe, undisturbed nesting and overwintering space.

Native hedging is a strong starting point. Hawthorn and holly, for example, provide dense shelter and nesting sites through spring and summer, then carry berries into autumn and winter when other food is scarce. Nectar-rich perennials planted alongside give pollinators a working food source through the growing season rather than a single short burst.

Whole peanuts should be avoided if fledglings are likely to be fed them directly, as they present a choking risk; a mesh feeder that breaks nuts into smaller pieces is the safer option. Hygiene is just as important as food choice: cleaning bird feeders and bird tables regularly and moving their position from time to time helps reduce the build-up of bacteria that can spread between visiting birds.

Feeding is straightforward but worth getting right. Meaty cat or dog food, or a specialist hedgehog food, is a better choice than bread and milk, which can cause digestive upset. A shallow dish of fresh water left out overnight is just as useful as food, particularly during dry spells in summer.
