A simple experiment folks!
1. Invest in one pack of slug nematodes.
2. Collect some slugs.
3. Mix nematodes to the label recomended dilution.
4. Obtain a small propagator and add about 3 cms of moist soil to the
base.
5. Place slugs in the propagator with a few lettuce leaves.
6. Drench the slugs and the compost in the nematode solution
7. Close the propagator lid.
8. Observe the slugs on a daily basis
9. Ask for your money back on the nematodes if you are not impressed by
the result (or lack of it!)

And what does that tell us about

a) the ability of nematodes to catch and devour non-captive slugs
b) the ability of nematodes to continue to clear the area of slugs when
slugs are being added on a daily basis

.... in other words, anything about the performance of nematodes in
clearing slugs out of a garden?

And precisely what would it cost to 'drench' in nematode solution the
average sized garden?

Somone else on this group
raised the question of how far do slugs travel.
Well, I'm not sure how far they travel but I do know that it takes them a
long time to get there. Where ever 'there is', is.

very perceptive , this is indeed a secondary effect allowing regular inspection under the slates in order to remove the slugs for destruction or resettlement.
