The answer to 'why is my cockroach swarms' is that cockroach infestations are often caused by factors like food sources, moisture, and harborage areas in the home. Cockroaches thrive in warm, dark, and damp environments and can multiply quickly if left unchecked. Seeing large numbers of cockroaches, especially at night, is a clear sign of an infestation that needs to be addressed.
Some common causes of cockroach swarms include crumbs or spills left out, leaks or standing water, and cracks or crevices that provide hiding spots. Cockroaches are attracted to these conditions and can breed rapidly, leading to a full-blown infestation if not dealt with promptly.
