The answer to 'why is my cricket infestation' is that crickets have likely found their way into your home, attracted by sources of food, moisture, and shelter. Crickets are a common household pest that can be difficult to control once they've established a presence.
Some common causes of a cricket infestation include cracks or gaps in the home's foundation or exterior, leaky pipes or excess moisture, and the presence of food sources like pet food or crumbs. Crickets can also be drawn to lights at night, making them more likely to find their way indoors.
