Slugs [Ugh]...
Slugs can be a destructive force in our gardens, but to
help with getting rid of these destructive little pests, here are some
solutions.
Mechanical: Seaweed, just put some around the
edges of your beds and they will keep the slugs away. Must be the
combination of sea salt and sand. Another method that seems to work is a sand
barrier on the bed edges. Diatomaceous earth is another method that seems to
have positive results. The old fashioned "beer" trap works as well,
but remember the slugs get some, and in Western climates put a roof on your trap
or the rain will wash away the beer.
Another good method is to put aluminium edging around your
most precious crops, then bend the top edge down at least an inch. This keeps
the slugs from crawling up and over and eating its way through your lettuce.
Chemical: Slug bait, put in coffee can with holes
punched in so only slugs can get in. Later's and Safer's now has a non-toxic [to humans and animals] slug bait that works really well.
A company in England has developed a nematode for slug control, but as they have not found the nematodes in slugs in North America yet that particular product will not be available in Canada for some time. Sorry, we are all waiting for that day.
