Barriers 

1.  Salt

Salt can work well as when the slugs go over the salt it dries them up.  However, rain will wash out the salt into the soil and reduce how well it works.

2.  Egg shells as a Deterrent

Only really truly organic if you buy organic eggs.  These are great to help with the battle, however, they should be used with other methods rather than relied upon on their own.

3.  Coffee Grounds

Many people have recommended using coffee grounds as the slugs do not like them.  You can get these from your local coffee shops like Costa or Starbucks.  Although these are less of a hazard than inorganic pellets they may not be strictly organic you would need to check your suppliers coffee to make sure. Maybe against EU law to use this method now though.  And how organic is would be would depend on your shampoo and conditioner.

4.  Hair

You can use your own hair removed from a hair brush or cut to stop them.  You would need a lot of hair though.

5. Ducks

Ducks like to eat slugs.

 6. Wool Pellets

wool pelletsWool pellets are designed to put a natural barrier up around your plants to prevent the slugs and snails from getting to them to eat them.

These pellets are completely natural soil association approved wool and are also recycled are organic.

They work by causing an irritant to the slug and also by absorbing their moisture.  In addition, they also reduce weed growth and release nutrients which is a great bonus.

  7.  Copper

Copper makes a great barrier.  However, you have to keep it clean or it loses its ability to stop the slugs.  Also, this assumes the slugs are not already in the soil or hiding out somewhere else.

8. Organic Slug Pellets

Slug pellets need to withstand rain and quite a lot of it here in (not so sunny) Cornwall.  There was one with great reviews that caught my eye.  Many people are happy with and say it works and that it withstands rain. As I said previously this didn’t work with the ones I got locally.  So this was music to my ears.

9. Slug Nematodes

natural slug killerThis is probably one of the best solutions for organic slug killing as it is truly natural and non-chemical, unlike the organic pellets.  Nematodes are microscopic worms.  They decimate slug populations and kill them without the need for chemicals.

All you have to do it pick the right time, not too hot and dry or too cold. Raining is ideal. Following the instructions on the packet your water them into your garden.  This one pack covers 40 square meters.

As they are a living product they only last about three weeks in storage.  Once applied they last up to 6 weeks so if you first apply them in March you may need 2 applications.

 10.  Slug Traps

You can also buy slug traps that you can place in your ground.  These capture and kill the slugs.

11. Garlic Spray

I have used garlic for my seedlings in the mini greenhouse and it does work to a degree but you have to keep on top of it.  As soon as it rains or you water the plants you have to re-apply.

All you do is crush up a couple of garlic cloves and pop into a water spray bottle.  You leave it a couple of hours and then spray. (It may pay to mix separately then strain as the bits of garlic clog up the spray).

Other Methods

Squishing or Chopping

Shudder!  I have accidentally done this but couldn’t do it on purpose, but if you are not squeamish you can go up in the evening with a torch and either squish them or cut them in half.

Hand Removal

I confess I don’t like killing anything really.  You can just go up in the evening and remove them.  Though what you do with them afterwards I am unsure as you are not meant to move them to a different location.
