Beer is the best slug killer. A little in the bottom of a plastic dish, and they'll drink themselves to death.

It saved our broccoli and cabbage.

yeah, I dug in cups that would fill up with slugs then the new slugs would eat the old ones. One or two would eat some broccoli per day until they all looked inedible.

4-5 bottles of beer per day could buy a lot of broccoli. It didn't add up.

That's fair. A relative left a 12 pack of stag at my house, so I used that gross stuff. I was less concerned about price that way.

With slugs, at least you can stomp a few of them into paste and gain a pyrrhic victory. Birds? You're the old man and his son in that Simpsons episode shaking your fist at the sky, upset because you can't shake harder.

That being said, 1000s of slugs is practically insurmountable unless you plan to salt the Earth (figurately and literally) or kill the entire neighborhood with fire. Both have...consequences beyond the initial issue. ;)

Besides the ones drowned in beer I collected about half a bucket every morning.

The solution would be for everyone in the neighborhood to grow food and get rid of their car so that the hedgehog population can grow to match the food supply.
