Snail and Slug Control
Organic Snail and Slug Control
Most gardeners know the joy of seeing fresh, new seedlings starting in their garden and also the disappointment of returning the next day only to find the new plant chomped all the way down to the roots. This is often the devastating work of slugs or snails.
This page will explore different types of snail and slug control. I have designed this page for readers to share information. If you have had experience with a particular method of snail or slug control, please tick the box next to the best answer. In this way, we should be able to determine the best way to get rid of slugs and snails.
If you haven't tried a particular slug control and would like to give it a go, make sure you come back here afterwards to share your success or otherwise with us! And if you have come across a successful, natural way to get rid of snails or slugs in the garden that I haven't mentioned here, please let me know in the guestbook at the end of this page.
Bear in mind that slugs and snails can be fussy eaters so different methods may work for different slimy pests.
Snail and Slug Traps
Kill slugs with a beer trap - Make a slug catcher
This slug trap is designed to lure snails and slugs into the beer where they will drown. It is best to place one trap every 16 square feet or so. To avoid drowning beneficial ground beetles, make sure the top of your container is not flush with the ground but raise it up 1 inch or so. If rain is expected, rest something loosely on the top of your container to prevent the rain from diluting the beer, while still allowing snails or slugs to crawl in.

Vote: Other snail and slug repellents
These repellents can be used around the entire garden bed, but some may be more effective as barriers around individual plants. These should not just be used as a ring barrier around a plant since slugs can travel underground and come up inside the ring. Instead fill in a circle all around the plant right up to the stem. Caution: some of these substances (e.g. lawn lime and wood ash) are quite alkaline. So it would be best not to use them around acid-loving plants or if your soil is already alkaline.
If you have tried one of these methods and found it successful, vote for that method by clicking the circle next to it then clicking the vote button. If you have used more than one method that was successful, vote for the most successful.

Note: a reviewer on Amazon said that this works well with slugs and as an added bonus, works well for fertilizing tomatoes.
Handpicking Slugs and Snails
Collect snails and slugs
Collecting slugs or snails during or after rain, early in the morning or at night with a torch is a free slug control method. They are often found sheltering in hidey holes and under mulch. You may like to leave a length of polypipe in the garden to entice them to shelter there. Or perhaps a plank of wood or folded newspaper soaked in a sugar solution. These will make it easier to find the slugs when you are on your collecting expedition.
This video also describes how to get rid of the slugs and snails after you have collected them.

Slug and Snail Predators
What eats slugs?
You may want to encourage large lizards, birds and frogs to visit your garden as these may eat your slugs and snails. Building a pond may attract frogs and toads to your garden. One gardener, on this forum, put out loads of bird seed which attracted the birds and cut down on the slug damage.
Owning ducks and chooks can be an effective method for controlling slugs and snails, especially if they have been trained to incorporate these slimy additions in their diet from ducklinghood or chickenhood.

Slug and Snail Habitats
Changing the slugs' and snails' habitat
Slugs and snails seem to favor certain plants or certain conditions over others. Because these slimy creatures are most active at night and prefer moist conditions, you could try watering your garden in the morning so that the soil's surface has a chance to dry out during the day. Read this experiment for some interesting information about watering times.
You could try drip irrigation so that only your plants get watered and not all the surrounding soil.
You could try getting rid of all favorable hiding places - debris, weeds, large stones, planks of wood etc. especially in dark, damp places. In areas with a severe slug problem, you may wish to remove the mulch.
You may also find that you can plant slug "decoys". If you are growing chrysanthemums and find that slugs prefer lettuces, you could plant some sacrificial lettuces amongst your chrysanthemums and collect the pesky vermin from these.

Which tactic have you found most successful
Chemical Snail and Slug Control
Organic slug control
Choose pellets which have iron phosphate as the active ingredient. You could place small piles inside a plastic container with the lid taped on (such as a margarine container) with a hole cut in the side to allow access for slugs and snails. This will minimize the risk to pets, children and other wildlife.
