The answer to 'why is my cockroach invasion' is that cockroach infestations are typically caused by unsanitary conditions, access to food and water, and lack of pest control measures. Cockroaches thrive in warm, moist environments and can quickly multiply if left unchecked. Common symptoms include seeing live cockroaches, finding droppings or egg casings, and a musty odor.
To solve a cockroach problem, it's important to first identify and eliminate the root causes. This may involve sealing cracks and crevices, removing food sources, and improving sanitation. Over-the-counter baits, traps, and sprays can be effective for small infestations, but for larger or persistent problems, it's best to call in a professional pest control technician.
