I had the same problem with slugs eating my hostas. Garden center sold me Eliminator by Fertilome. One dose worked for about a month. Reapplied last night but I don't think slugs are the problem now. We are seeing an influx of grasshoppers.

Be careful what you use. Some products are toxic to way more than slugsÂlike pets, for instance.

I have excellent results from using Sluggo, which affects only slugs.

Diatomaceous earth. Cuts them up. Harmless to pets.

Just don't put it around the beardless iris. It's made of tiny shells of microscopic critters and the excess calcium will set siberians back and kill ensata's. The regular bearded iris will love it.

A shallow dish of cheap beer is also hard for them to resist. They crawl in and drown with a smile.
Both work. Not the total anilation of chemical pesticides but it does seriously dent the numbers. Much safer for everybody that way too. Pets, kids, butterflys and bees stay safe.

Snails? with all this rain I have ducks and tadpoles in parts of the yard. No joke!
