Biological Pest Control: Nematodes As A Chemical-Free Option

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.

A pond set up with the right planting and shelter from the outset tends to attract amphibians naturally over time. Many gardeners begin with a considered selection of pond wildlife equipment chosen to suit the size of pond they are working with.

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.

Sited well and left in peace, an insect house can become a genuinely busy part of the garden. Many gardeners start by comparing a few insect houses before choosing one to match the space available.

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.

Not every beneficial garden insect lives in a hive or a colony. Many UK bee species are solitary, nesting alone or in loose aggregations, and insects such as lacewings and ladybirds shelter individually or in small clusters, particularly over winter. An insect house gives these species something a tidy garden often lacks: safe, undisturbed nesting and overwintering space.
