Biological Pest Control: Nematodes as a Chemical-Free Option

Birds need consistent feeding through frosty spells, when natural food sources are hardest to find and energy demands are highest. Keeping feeders topped up, and providing water that is not frozen over, matters more in a hard frost than at almost any other point in the year; a small area gently melted with warm water is a better approach than breaking ice by force.

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.

Feeding is straightforward but worth getting right. Meaty cat or https://www.provenexpert.com/en-gb/garden-wildlife/ 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.

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 care is really about restraint. Amphibians often spend the coldest months dormant in mud at the pond bottom, so the pond is best left undisturbed rather than cleared out or heavily managed during this period. If the surface freezes over, gently melting a small area with warm water is a gentler approach than breaking the ice directly above where they may be sheltering.

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 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.
