The answer to 'why is my cockroach invasion' is that cockroaches are a common household pest that can quickly multiply and infest a home. Cockroaches are attracted to food, moisture, and clutter, and they can enter a home through cracks, crevices, or even hitchhike on boxes and bags. Symptoms of a cockroach infestation include seeing the insects themselves, finding droppings or egg casings, and noticing a musty odor.
To address a cockroach problem, it's important to first identify and eliminate the root causes. This may involve sealing up entry points, removing food sources, and reducing moisture. While some minor infestations can be treated with DIY methods like baits and sprays, a severe or persistent cockroach problem is best handled by a professional pest control technician who can provide more effective and long-lasting solutions.
