There are entomopathogenic nematodes for sale on almost every
gardenening site, but do they actually work?

Has anyone undertaken a study to show that leatherjackets, chafergrubs,
slugs etc.. are actually killed by these natural worms? If they are so
effective, then how come we have any wildlife left alive!!?

We have a serious problem on our allotments with ground dwelling slugs and
used Nemaslug on our potato bed last year. It's quite expensive, only lasts
6 weeks so needs redoing, and didn't seem to have any effect at all. We
still lost a significant proportion of the crop (and planted slug resistant
varieties). Waste of money as far as we are concerned.
I presume these nematodes aren't native and that's why they need
re-applying: is it that it's too cold here for them to survive and breed?
