Cockroaches are stubborn insects, and they can infest even in a clean house. They hide in corners or areas that are difficult to reach, and they multiply fast. They usually come out at night and infect your utensils, floors, and food with bacteria like salmonella. Over-the-counter products may give you results for a few days but they don’t work in a long run. Going for pest control can give you relief for a long time.
