Newer products on the market use iron
phosphate as the active ingredient, which is much less toxic for
people, pets and other creatures. Iron phosphate is sold under trade
names such as Escar-go and Sluggo. These slug baits must be
re-applied after rain.
Slugs love Hostas!
An alternative that has been used with some
success is to sink aluminum pie plates into the soil around the
affected plants so that the rim is at ground level. Then fill them
with beer. Fortunately slugs are cheap drunks, so the least
expensive beer will work fine! They are attracted to the beer, fall
in and drown. Clean the traps and replenish the beer as needed.
There is some evidence that beer (actually the yeast) attracts more
slugs to your garden than you might have otherwise.
ALTERNATIVES FOR SLUG CONTROL
Other alternatives include surrounding the
affected plants with coarse sand, ground eggshells or diatomaecous
earth. Slugs do not like to crawl over these jagged materials. They
are soft-bodied, and the sharp materials can cut them to death. They
must be replenished after rain or heavy dew to be most effective.
