Prevent a Garden Slugfest With Baits, Upkeep
Effective snail and slug management calls for a combination of garden upkeep and trapping. As for the most commonly used homemade baits, however, put away the saltshakers and leave the beer in a cooler, said Robin Rosetta, an entomologist with the Oregon State University Extension Service.
"Table salt can dry up the mollusks but it also can build in the soil over time, damaging plants," she said. "Fermented sugar water and yeast is cheaper than beer-baited traps and just as functional for drowning slugs."
