Natural Born Killers


After raising, nurturing and cajoling your baby plants into health, then casting them adrift in their raised beds, there is nothing more disheartening than to have a night attack of encircling slugs.

From my modest gardening experience, in (the last 13 years in 3 different gardens) the best ‘organic’ slug killer is a large dose of microscopic nematodes.

As far as I am aware, there is only one brand that supplies them fresh, boxed and ready to apply, and that’s Nemaslug. Lots of sites seem to sell the same brand, and nematodesdirect seem to be as good a site as any.

I’d highly recommend Nemaslug, especially for your first application, as I’ve found this reliably knocks the slug population right back and seems to stunt its recovery for some time thereafter.

Although they do recommend subsequent applications, it is expensive, especially if your plot’s on the large side.

You can start to farm your own nematodes using a simple recipe and keep it going for a while (a bit like you would yoghurt or sourdough bread). I’d recommend an as-much-as-you-can-afford dose of Nemaslug first, then a smaller top-up application a few weeks later, and then having a go at the DIY version thereafter.

I seem to have mastered it, with a bit of worryingly obsessive slug farming. I’ll let you know if I’m happy with the results later in the year.
