Biological Pest Control: Nematodes As A Chemical-Free Option

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.

Shelter is often overlooked. Many UK bee species are solitary rather than hive-dwelling, and a patch of bare, undisturbed soil in a sunny spot can serve as nesting ground for mining bees, while hollow stems and GardenWildlife drilled wood blocks suit species that nest above ground. Choosing biological pest control over chemical sprays around flowering borders also helps protect the insects visiting them.

Nematodes are microscopic roundworms that occur naturally in soil, and certain species have been developed for use against specific garden pests. Rather than acting as a broad chemical treatment, each nematode species is matched to a particular pest, seeking it out and interrupting its lifecycle with far less impact on the rest of the garden than a chemical spray.

Winter is one of the harder seasons for garden wildlife. Natural food becomes scarce, cold weakens smaller animals quickly, and many species rely on undisturbed shelter to see them through to spring rather than active foraging.

Design has a big influence on how well a pond 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.

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.
