Cockroaches often find their way into your home through cracks or under doors. These small spaces are often large enough to accommodate these tiny creatures. The smell of food particles will also attract them to your home. If you have children in your house, they can leave crumbs and other items on the floor that attract these pests.
Roaches are highly resourceful and can squeeze through tiny cracks and holes to enter your home. Some species can fit through openings as small as 0.15 centimeters. Other entryways include holes in plumbing fixtures and pipes. You may also find roaches hiding in used furniture and bags.
The best way to prevent cockroaches from causing damage to your home is to keep your food and garbage containers clean. The smell of food and moisture will attract roaches. Also, keep your trash bins tightly sealed to keep out pests. If possible, place glue strips in areas where you see roach activity.
Cockroaches are attracted to moist, dark places, and water sources. They often live in kitchens, bathrooms, and other places that have a lot of water. They are more dependent on water than food for their survival, but they can survive a few days without food.
