Insects overwinter too, tucked into log piles, leaf litter and insect houses left undisturbed until spring. Gardeners preparing shelter ahead of the colder months often look at buy hedgehog houses online options early, so everything is in place before the weather turns.

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.

For gardeners wanting an alternative to chemical sprays, a soil-applied option is worth considering as a first step, and a good starting point is a range of slug nematodes for gardens suited to the pest in question.

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.

Design has a big influence on how well a pond wildlife equipment gets used. A shallow, gently sloping edge, sometimes called a beach area, lets amphibians and insects get in and out easily, and gives small mammals that fall in an escape route rather than a hazard. Planting in distinct zones, marginal plants at the shallow edge, floating plants across the surface, and oxygenating plants below, gives different creatures the cover and conditions they need.
