Leather Jacket control with Steinernema

from £12.99
Tax included.

Leatherjackets

Leatherjacket's feed on grass roots from September and through to the following summer. They are legless greyish brown larvae of the crane fly (daddy long legs). They pupate in the summer and adults emerge in August, sometimes in huge numbers, ready to lay eggs again. The larvae weaken the lawn which can then be pulled up by birds feeding on the larvae. Larvae may move from lawn areas to neighbouring flower beds.

Control with Parasitic nematodes (Steinernema feltiae)

These microscopic transparent worms feeds and mulitiply inside the larvae causing death. Supplied as an easy-to-mix powder to be diluted with water before use. Apply to moist compost/soil using a watering can or sprayer. 

Use treatments between September and October for effective control. A second treatment may be applied the following spring or in mild autumns.
