No one wants to see these little pests inside the house unless they're of the costumed variety. Take a cue from your own backyard by outfitting yourself and your tyke in an insect-inspired costume set. Super-cute buggy options include ladybugs, butterflies in your favorite colors and a spider and a fly. You could even dress up as a bee and his favorite flower. However, you might want to stay away from dressing your child as a praying mantis or large, nasty beetle. It might seem funny now, but you don't want to look back at pictures of the two of you years later and think "eww" instead of "aww."
