Was it in spring? Because that's when you ought to do it. Twice at 3
weeks intervals. You will see the results the following years by seeing
less or none of the tiny little black slugs. I'm looking forward to
next spring to give my experiment a scoring point (cross fingers ;o)

Tu es francais?

Belge!

Don't remember when I used it (long time ago), but I think the conditions
were within the acceptable, temperature-wise. My mistake, probably, was
spraying only the borders and not the other parts of the garden which
looked like "slugs and snails" refuges. But then, I realized that if I
wanted to spray my entire garden, it would cost me a real fortune! Yes,
BTW, the main culprits in my garden are snails rather than slugs, and it's
not quite clear to me if the nematodes work against snails as well?

Unfortunately the Nematodes do not work particularly well against snails.
Not totally useless, but only a small mortality in snails:-(
A relatively new killer in the UK is Ferric (Pyro)phosphate which seems to
work OK and has the benefit of being safe and beneficial to the soil.
AFAIK it is the same stuff that is used medicinally for anaemia.
