Household pests want the same things you do—food, water, shelter—and will seize any opportunity to satisfy their needs. You can’t stop every pest from ever flying, crawling, or burrowing into your home, but you can make sure the occasional intrusion doesn’t become an all-out invasion.
Once a major infestation occurs, you’ll likely need professional help. But if you focus on prevention, you can tackle many aspects of pest control yourself, save money, and avoid adding pesticides to the environment.
