Codling Moth Nematodes Treats 16 Trees

Fruit Tree Pest Management for Codling Moth Larvae

Codling moths can cause significant damage to apples, pears and other fruit trees. Their larvae burrow into the fruit, making it unfit for harvest.

This product treats approx 16 trees and uses a mix of Steinernema nematodes to help reduce codling moth numbers by targeting their larvae during vulnerable stages.

Best Times to Use Codling Moth Nematodes in the UK

Apply the treatment in April – late June, and again September/October, when overwintered larvae begin hatching, and again in Autumn to control new generations before they pupate. These seasonal timings help stop pests before they damage developing fruit.

Use Alongside Codling Moth Traps

To increase your chances of success, pair this product with codling moth traps during summer. These traps help reduce adult moth numbers and provide early warning for infestations. Fewer adults mean fewer eggs laid at the end of the season.

Visible Signs of Codling Moth Infestation

Look for holes in fruit, brown trails under the skin, or apples that fall early. Codling moth larvae are white with a brown head and usually remain hidden inside the fruit. Using this treatment helps reduce further fruit loss during the growing season.

Safe for Family Gardens, Edibles and Wildlife

This biological control method is safe to use around pets, children and garden wildlife. It poses no risk to pollinators and has no impact on harvest time. Simply apply with a watering can or applicator no special equipment required.
