One application of Nemaslug Slug Killer will provide at least 6 weeks control of all common species of small to medium sized garden slugs.
If you start applying nemaslug early in the season, you can target the young slugs growing under the ground. Unlike chemical pellets, the slug killer nematodes continue to work well during wet weather - exactly when you need protection against slugs
Nemaslug Nematodes are easy to apply using a watering can and do not leave any unsightly residues. Each application of nematodes will provide at least six weeks control of slugs. This is generally enough time for seedlings and bedding plants to get well established. The majority of the slugs will die underground, so don't expect to see dead slugs lying around.

Apply Nemaslug to moist soil. The soil temperature should be 5ºC or over (this is also when plants start to grow). Nematodes are capable of surviving the odd frost; so don't worry if the temperature falls after you have applied Nemaslug. Slug pellets are reported not to be effective below 7ºC.
Potatoes are susceptible to slug attack later in the season than most other plants. Apply Nemaslug Slug Killer 6 weeks before harvest, when the tubers are most likely to be eaten by slugs. If you have a heavy clay area, ensure you apply Nemaslug to well worked soil. Nemaslug is less effective on cloggy clay soil, which has not been worked and/or has become waterlogged.
Nemaslug might affect water snails. To avoid harming them keep the treatment 15 cm away from ponds.
The Nemasys / BASF Technical Specialist has answered this question as followed.....
"The nematodes can be applied over the top of the mulch and they'll find their way down to the soil through the spaces between the bark chips no problem.
However it's recommended to apply water right after the application to wash the nematodes down and keep an eye on the soil moisture content; it should be kept moist for at least two weeks after the application.."
"Nemaslug contains the beneficial nematode Phasmarhabditis hermaphrodita which is naturally occurring in the soil and is specific to gastropods. What it means is, this nematode species is not harmful to mammals such hedgehogs, even if swallowed. On the contrary, it is an effective biological control of slugs. Infected slugs stop feeding quickly and die below ground within 4-21 days. Nemaslug and Nemasys are biological control agents manufactured by BASF and are safe for children, pets and wildlife. A regular regime of using Nemaslug every 6 weeks will keep slugs at bay and will not harm hedgehogs.
Most slug killers are applied to the surface of the soil. Slugs spend most of their time underground, coming up at night to feed. Depending on slug species, some do not even come up at all if they can feed on starch-rich tubers such potatoes. Nemaslug instead, will literally chase the slugs in the soil and kill them.
Some of the slug pellets for example contain methiocarb. This chemical is a non-selective carbamate that acts as a stomach poison and is generally toxic to other organisms such as birds and hedgehogs."
