Disheartening isn't it? Your Blue Mouse Ears are so pretty, too. My Blue Mouse Ears is one of the few that haven't been eaten in my garden. I have gone out with the flashlight and sprayed and put out three containers of bait so far this year. No dice. This has been an awful year for snails and slugs. The hostas that always get a few holes are like Swiss cheese this year.

Have you considered that the Snail eggs may have been deposited in the soil before you brought the plants indoors?
I like to sterilize the soil before planting any container, that will be used indoors, since we have a troublesome ant problem in my area. The black vine weevil is also a serious pest.
I haven't experienced a problem with Slugs in many years. Haven't observed a Snail in the garden in more than 20 years. The few Slugs that manage to survive, go for the Tricyrtis (Toad lilies) and usually leave the Hostas alone.
One application of Sluggo usually remedies that problem.

There is a Family of Opossum living in the woods, somewhere in the area and I observe them feeding in the garden at night. Catch one occasionally in my Hav-a-hart squirrel trap.
The Opossum is omnivorus, eating fruits, vegetables, grass, but also snails, slugs, worms, snakes, rats & mice, amphibians, some types of fish, carrion, table scraps and certain types of pet food.
With a woodland habitat, there are dozens of bird species feeding, sheltering & nesting in the area. Some of those will eat slugs.
Summertime brings out the Fireflies, which deposit their eggs on slugs. When they hatch, they consume their host!

A den of Red Fox downhill, near a creek, keeps the rabbit population at Zero and roaming coyotes eliminate the occasional deer threat.

If you can tolerate the loss of a few vegetables and fruit and keep the berried plant seedlings pulled from the flower beds, Nature, on balance, can be a great advantage to gardeners,

Now, if we could do something about the weather!
Hail, lightning, destructive windstorms, severe to exceptional drought for 2-3 years, then devastating floods and serious erosion.
Dreaming, of course!

Lady Windsurfer-

These plants are always outdoors. This is an atrium with a 2x2" overhead covered by shade cloth. All these plants have have never been in the ground, and they all come shipped bare root and I use bagged potting media. I use lots of Sluggo, and occasionaly stronger insect killer when those vine weevels begin to do their notching on the leaves.

My hostas spend their entire lives here, with perhaps a dozen or so spending summers on the deck outside our familyroom/kitchen area so I can see them all the time.

They are protected from Frost, Wind, Hail, Floods, Direct Sun and Hot temps. But I cannot totally protect them from getting chewed by the freeking slugs/snails.

I have no clue about how a 1/2" snail can get to my plants. Yup, Nature can be amazing.

A quite beautiful room for hostas. Good luck with protecting them.

Babka,

That is a fantastic setting for display of your hosta. Just beautiful.

Your room is gorgeous! We see some beautiful and amazing gardens here and it's a treat to see other ways of showing hosta!

Yes, I love your Hosta room! Slugs are dasdardly little beasts, aren't they? Here in the tip top of the UP, my first hosta leaves are only now starting to open and already we're spotting slugs, although no damage yet.
