Chemical solutions can be highly effective, but indoors, for obvious health reasons, you're much better off with something like the Electronic Insect Killer from Pure Enrichment. The lightweight device hangs easily in any room, and its sleek silhouette meshes well with modern decor. How does it work? First, it uses ultraviolet light to lure insects within a 860-square-foot radius. Next, it zaps with a 2,100-volt burst of electricity. If the thought of dead bugs makes you queasy, don't worry—the removable collection tray makes cleanup a cinch. Available on Amazon; $49.99.
