Your mom always told you to take out the trash, and for good reason. A loaded garbage can is not only unsightly and possibly smelly, but it's yet another attraction for insects and unwanted critters. They're attracted to your refuse for many reasons. Perhaps there's tasty, rotting food inside. Maybe there's moisture or liquids. Or your garbage might just make a snuggly place to hang out for a while [source: Food-Safety-And-You].
Ideally, you'll have a garbage can with a tight-fitting lid that's always secured properly. Then, you'll empty it regularly, especially if there's anything smelly inside. And don't forget to regularly clean it, too. Garbage cans or bins often have all sorts of sticky or sweet residue on them from drips and spills as you're tossing stuff inside.
