I guess it was the spring of 2018 I went crazy and got 25 new chicks (added to my 4 girls) that it was like a horror show here after a rain. At night, I could go out onto my back deck and they were literally EV-ER-Y-WHERE! My master bath and closet are add-ons and have white siding. These things were all on the walls, the eaves, the gutters, the deck, and of course all my new plantings.

It was war and I wasn’t winning. I bought salt to pour on them. Kind of got the same feeling seeing them shrivel as I did watching fire ants die.
Our back deck is about 2’ off the ground and it is nasty as hell under it. No person has crawled up under it. You couldn’t pay me to. It mostly stays wet simply from all the flower watering, water play, cooling off, etc. on the deck. Obviously this is where the slugs bedded down AND overwintered. That summer (2018) my 29 chickens decided they liked it under the deck. My two dogs had been staying under there during the day to escape the heat as well. That next summer (2019) I barely saw any slugs at all. Every once in a while I will see where a slug has been up on the deck after the dog food, leaving their old slimy, iridescent trail behind.
Once I decided I wanted ducks, I have been worrying about under the deck. I know that that will be the CHOSEN duck hang out unless I fence the whole thing off to all critters. I can’t and won’t be Easter egg hunting for duck eggs under there.
I’m really kinda torn cause I liked the chickens and dogs getting under there, keeping all other varmints run off or eaten. I guess I’ll choose the lesser of two evils when the time comes.
