"Slug-o-matic"

empty 2-liter plastic bottle
stapler
slug bait

Cut the top 3rd of the bottle off. Drop a spoonful of bait into the
bottom of the bottle. Push the top portion of the bottle (inverted)
into the bottom and secure with 3 or 4 staples.

Use the trap for several weeks, then toss it out. The bait is
protected from rain and pets. This trap has proven to work better
than messy beer traps or spreading the slug bait onto the ground.
