We have a slug problem here, but I have heard that a weak ammonia solution can kill slug eggs.
In addition, I will be using homemade slug traps for them to drown in, slug bait, and scrap pieces of wood laid down for them to hide under. It will just be a matter of doing a slug check every day for a while and exterminating any I find post haste.
Yeah I guess slugs like beer. Don’t have many slugs here but plenty of airborne pests. Japanese beetles are really bad some years. One year they ran out of peach tree leaves so they started eating the peaches. Got the usual aphids and tomato hornworms but those aren’t too bad to deal with.
