Biological Pest Control: Nematodes As A Chemical-Free Option

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 feeders regularly and moving their position from time to time helps reduce the build-up of bacteria that can spread between visiting birds.

Nematodes are microscopic roundworms that occur naturally in soil, and certain species have been developed insect houses for garden pollinators 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.

Bringing these elements together tends to work best gradually, adding one or two features at a time. A useful starting point is a browse through wildlife friendly garden products UK gardeners have found practical for exactly this kind of layout.

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.

Frogs and newts are useful garden residents, feeding on slugs and other insects, and their presence is generally a good sign that a pond is in reasonable health. Attracting them is mostly a matter of getting the habitat right rather than anything more involved.

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.
