The answer to 'why is my cockroach bites' is that cockroaches do not actually bite humans. Cockroach bites are a common misconception, as cockroaches are not known to feed on human blood or skin. Most often, the 'bites' that people experience are actually caused by other pests, such as bed bugs, fleas, or mosquitoes.
If you are experiencing what you believe to be cockroach bites, it's important to properly identify the pest causing the issue. Bed bugs, for example, leave behind distinctive bite marks that are often mistaken for cockroach bites. Calling a professional pest control technician can help accurately diagnose the problem and recommend the appropriate treatment.
