The first thing to do to prevent roaches in your home is to keep your house clean. Roaches will find shelter, food, and water in areas where there is clutter. To keep roaches out, remove cardboard boxes and other items from your home, and clean out your cabinets and drawers thoroughly. Also, store food in airtight containers.
Roaches often get into your house unintentionally. They are small and can sneak into your house by hiding in your purse, briefcase, or even your child’s backpack. These insects can also infest your home from other homes, especially if you share living space with a neighbor. Having a roach infestation in your home can make you feel nervous.
Cockroaches can live up to a year. They can survive without food or water for up to a month. Because they reproduce quickly, they can cause a major infestation if left untreated. A single female German cockroach can produce 120 to 385 babies in her lifetime.
Even if your house is clean, cockroaches can find a way into your home. Cracks in walls and foundations are common entry points for cockroaches. They can also enter through rips in clothing, backpacks, and screens. Cockroaches can also enter through plumbing and air conditioning units.
