The answer to 'why is my cockroach recurring problem' is that cockroaches are resilient pests that can be difficult to fully eliminate. Common causes include access to food and water sources, cracks and crevices that provide hiding spots, and resistance to many over-the-counter pesticides. Symptoms include seeing live cockroaches, egg casings, and droppings. To solve a recurring cockroach problem, you'll need to address the root causes through a combination of sanitation, exclusion, and targeted treatment.
Cockroaches can spread diseases, contaminate food, and trigger allergies, so it's important to take action. DIY methods like baits, sprays, and traps can provide some relief, but for a severe or persistent infestation, it's best to call in a professional pest control technician. They have access to more powerful treatments and can develop a comprehensive plan to eliminate the cockroaches and prevent them from coming back.
