Delivery of nematodes is timed to coincide with optimum soil temperatures. We will start despatching from August.
Soil temperature in August is at an optimum level for the nematodes to destroy the grubs.
Use Nemasys Leatherjacket Killer to deal with a leather jacket infestation, without any of the precautions associated with chemical use.
When you start to see the adult daddy-long-legs in your garden (towards the end of August) you will know that in a few days they will be laying eggs. These will hatch quickly, within two weeks. The young start to feed, continuing throughout winter, ready to gorge on grass roots in spring.
The nematodes (Steinernema feltiae), seek out the leatherjackets and attack the pest by entering natural body openings.
Once inside, they release bacteria that stops the pest from feeding, quickly killing the pest. They do not stop there. The nematodes reproduce inside the dead pest and release a new generation of nematodes, which disperse and search for further prey.
When you receive your pack of Nemasys, place it in the refrigerator immediately and use within the use by date (which can be up to four weeks).
