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.

Access is usually the first barrier. Solid fencing and walled boundaries cut a garden off from the wider network a hedgehog relies on. A gap roughly the size of a CD case cut at the base of a fence panel, sometimes called a hedgehog highway, lets them pass between neighbouring gardens without needing to cross open roads or driveways.

Different nematode species target different problems. Some are used against slugs, others against vine weevil grubs feeding on plant roots in containers and borders, and others against chafer grubs or leatherjackets damaging lawns. Because they are pest-specific, the right choice depends on identifying which pest is actually causing the damage.

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.

order nematodes for slug control 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.
