Slugs are homeless snails; they never had need of a Realtor because they never had need of a house.
To find out if you've been infested with slugs look for them at night munching on your foliage, especially anything in the Hosta family; or look for their slimy trails in the morning.
So far, chemical baits have been hard to find; they make an appearance and then are quickly removed from the shelves it seems.
But fortunately for us they have a nemesis; they can’t stay away from the booze.
Beer is a big problem for them; and like ants to a wet sucker, or moths to a flame they can’t seem to resist the “call of the brew”; and they aren’t sophisticated around it either. Nope, they just dive in like the sloppy drunks they are; no sipping around the rim, no little slug beer stein, just headlong into a pool of it and die.
To make these libation death traps take a mayonnaise jar lid and bury it in the ground so the top of the lip is just above the ground. Fill it with stale beer or a mixture of 1 teaspoon of yeast and 2 teaspoons of sugar in 3 oz. of water. In the morning empty out the drowned slugs and ready it for the next swim meet.
Whether you use beer or the mix do not use the same liquid more than 48 hours.
