The answer to 'why is my silverfish invasion' is that silverfish are a common household pest that thrive in damp, humid environments. They feed on carbohydrates, starches, and sugars found in things like paper, books, wallpaper, and even clothing. Silverfish infestations are often caused by excess moisture, poor sanitation, or improper storage of food and paper products.
Silverfish can be identified by their distinctive teardrop-shaped bodies and long antennae. They are nocturnal and often hide in cracks, crevices, and behind baseboards during the day. Signs of a silverfish problem include seeing the insects themselves, finding their shed exoskeletons, or noticing damage to paper goods, fabrics, or other household items.
