The answer to 'why is my cockroach infestation' is that cockroaches are a common household pest that can be caused by a variety of factors, including food sources, moisture, and entry points in the home. Cockroaches are attracted to food, water, and warm, dark environments, and they can reproduce quickly, leading to an infestation.
Common symptoms of a cockroach infestation include seeing the insects themselves, finding egg casings or droppings, and noticing a musty odor. Cockroaches can also carry diseases and contaminate food, so it's important to address an infestation promptly.
