Biological Pest Control: Nematodes As A Chemical-Free Option

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.

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.

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

Connectivity between gardens is often the missing piece. A small gap at the base of a fence, native hedging used in place of a solid boundary where practical, and less hard paving all help animals move between plots rather than being boxed into one. These small changes add up meaningfully over the course of a season.

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.

Placement decides whether the house gets used at all. A fixed position at around waist to head height, facing south or south-east to catch the morning sun, and sheltered from driving rain and strong wind, gives insects the stable conditions they need. Once occupied, the house is best left undisturbed through the nesting and overwintering period.
