Most of your slug problem starts outside. They don’t spawn in your hallway—they crawl in from the garden. So, clean up debris like piles of leaves, old wood, or stacked bricks. Slugs see those as luxury condos. Also, keep your grass mowed and your flower beds tidy.
I learned this the hard way after ignoring a pile of rotting logs for a year. One rainy night, I came home to find a slug highway leading from the pile straight to my cat’s food bowl. The cat looked at me like, “This is your fault, Dad.” He wasn’t wrong.
