Slugs and Snails
Devestated vegetables
Leaf damage
Description
There’s no need to tell you what they look like. And the silvery trails will tell you where they came from and where they went on to after lunching on the juicy Hosta. But here are a few interesting/amazing facts that give clues as to just what the gardener is up against.
Up to 90% of slugs will be hiding underground during the day. In a cubic metre of soil will live on average 200 slugs. That means in an average sized garden there will be up to 15,000 slugs - and then there are the snails! They love it mild and damp but they will still be around and hungry in the Winter if the temperature stays above 5°C.
Symptoms
Skeletal or near skeletal foliage. Holed tubers (potatoes, carrots etc) or bulbs. Pretty obvious stuff really!
Treatment and control
General tips
No garden will ever be free of slugs and snails. The approach should be to protect vulnerable plants. But at the same time, if you come across a slug or a snail you would be well advised to pick it up and dispose of it.
Surface control using pellets
Scatter pellets containing metaldehyde on the soil around vulnerable plants. A good example would be SlugClear Advanced Pellets, which are effective against all slugs and snails. The pellet contains 50% less chemical than traditional pellets. A word for pet owners: We recommend that you keep SlugClear Advanced Pellets out of the reach of children and pets, both in storage and in use.
Surface and underground control
Water over and around decorative vulnerable plants using a diluted concentrate liquid containing metaldehyde. This will deal with all those slugs that can’t be seen as well as those slugs and snails which can. An example of this is SlugClear, which is a liquid and therefore invisible to pets. SlugClear gets to where the slugs and snails are - underground.
Biological control
Not effective at surface level but an underground option. Parasitic worms or nematodes can be introduced to the soil and can help control slugs. They penetrate the slug and kill it.
The beer approach
If all else fails why not offer the pests a drink:
- Half fill a jam jar with beer.
- Sink it into the soil, its rim approximately 1cm above the soil surface (this prevents the good guys ie. beetles from falling in).
- The aroma never fails to attract and in seeking its source the pests simply fall in, drink the lot and get so drunk they can’t climb out! No they don’t, they drown!
