Solutions like Decon can cause a big problem when they wander off -- dead animal decomposing and drying inside your walls or in unexpected places. The stink lasts about a week in a really dry environment, but if it's warm or humid count on being grossed out for longer. Use a snap trap, and place the business end of it with the bait butted up against a wall, because the little critters usually skitter along next to a wall or vertical surface and will then have to step over the trap and trigger it.
