Insect Houses: Giving Solitary Bees And Beetles Shelter

Fish are worth thinking through carefully. Ornamental fish will happily eat frogspawn and tadpoles, so a pond intended mainly for amphibians is usually better left fish-free. Leaving some leaf litter to settle at the bottom over autumn also gives amphibians a place to shelter through the colder months.

A pond set up with the right planting and shelter from the outset tends to attract amphibians naturally over time. Many gardeners begin with a considered selection of pond wildlife equipment chosen to suit the size of pond they are working with.

Native hedging is a strong starting point. Hawthorn and holly, for example, provide dense shelter and nesting sites through spring and GardenWildlife 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.

Bees and other pollinating insects rely on gardens for a large share of their food, especially in built-up areas where wildflower meadows are scarce. A garden that offers flowers from early spring right through to autumn does far more for pollinators than one with a single showy burst of colour in June.

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.

Application is simple but does depend on getting the conditions right. Nematodes are typically mixed with water and applied with a watering can or hose-end feeder directly onto moist soil, since they need moisture to move through it and reach their target. Soil temperature also matters: most products need the soil to be above a minimum threshold, often around 5°C, to remain effective.
