Summarize this article in one sentence.
After opening the glue trap from the package, set it on the ground with the glue facing upward. Place bait next to or on top of the glue trap to lure the mice.  Glue mouse traps use glue trays with scented substances that attract rodents. Once the rodent has stepped into the trap, it sinks further into the trap until it dies. Keep in mind that glue mouse traps are considered the least humane traps because they kill mice by starvation or suffocation, which can take days.

Summary:
Place glue traps near or on bait.
