The basic idea is that you collect a whole bunch of slugs from your own garden, which will naturally have a low nematode population. You keep them in a crowded and unhealthy jar - think a slug slum - so that they survive for a week or so picking up nematodes from each other. Eventually the slugs sicken and die releasing lots of nematodes into the liquid. Dilute the liquid in a watering can then spread around your garden. The nematodes hunt out slugs in and on the soil and kill them within about a week. The dose should last about 6 weeks in the soil, before needing to be repeated.
