In the popular 1995 comedy film “Houseguest,” Sinbad portrays a con artist on the run from the Mafia. To avoid being caught, Sinbad poses as a long-lost friend to an unsuspecting suburbanite played by Phil Hartman and moves in as a houseguest. Sinbad’s antics charm the family; however, he eventually becomes an unwelcome house pest when the Mafia locate him at the family’s residence [source: Rotten Tomatoes].

Pests such as insects and rodents are not always as obvious but can be just as bothersome. Imagine waking up to a tick burrowed in your skin or a rat that has eaten all of your cereal.

Once pests have made your home their own, there are many ways to get rid of them, from raccoons to cockroaches. Exterminators are the preferred choice among Americans, with the pest control industry in the United States generating about $7 billion in annual revenue [source: Hoovers]. Although exterminators typically use poisonous chemicals to kill pests, these chemicals can also be harmful to humans. A 2003 study by the Centers for Disease Control (CDC) found that the average person has at least 13 different pesticides in their body, some of which have been associated with health issues such as cancer and nerve damage [source: CDC].

However, what are the alternatives to pest control? Besides calling in an exterminator, how can you prevent pests from entering your home? Actually, a green alternative may be the best option. Learn about a very eco-friendly way to keep your home pest-free on the following page.

The best way to keep pests out of your house is to prevent rodents and insects from entering in the first place. If you take a closer look at your home’s envelope (exterior walls, doors, windows, and roof), HowStuffWorks.com guarantees that you will find some surprising entry points. Bugs and rodents can come in through cracks in your foundation, unsealed windows, and gaps between your walls and floors. Sealing these areas with caulk can help prevent pests from entering and also save you on home energy costs.

Despite your best efforts, household pests may still find their way inside. However, you can make your home as inhospitable to rodents and insects as possible to combat them once they’ve entered.

Insects require food, water, and shelter to survive. They don’t get these resources from the faucet or grocery store like humans, but rather from overlooked sources. For example, standing water in a dish under a potted indoor plant is a watering hole for pests like cockroaches, mice, and flies. Check your house for other areas with standing water, remove this source, and pests will not want to live there. Pantry items like cereal, pasta, and cookies are a feast for pests, and they can chew through cardboard packaging. Keeping these items in hard metal or plastic canisters will discourage hungry pests. Cleaning your house regularly, especially where food is prepared and eaten, will also discourage pests from sticking around. Removing clutter and stacks of old newspapers and boxes will also reduce their living space. However, not all creatures are pests. Spiders and lizards, for example, can help control the population of household bugs.
