Georgia Pest Control Practice Test

What type of material do silverfish feed on?

1. Metallic materials

2. Cloth materials

3. Starch-containing substances

4. Wood-based products

The correct answer is: Starch-containing substances

Silverfish primarily feed on starch-containing substances, which include materials like paper, cardboard, and the starchy components found in some types of fabric and food. Their diet is heavily reliant on carbohydrates, making them particularly fond of items such as book bindings, wallpaper, and even the starch in glue. This feeding behavior is why they can be considered pests in homes, as they can damage various materials, especially those rich in carbohydrates. It's important to understand that while silverfish may be attracted to a variety of materials, their preference for starches is what characterizes their feeding habits and can lead to specific infestations, particularly in areas where books, old newspapers, and starchy food products are stored. By knowing their dietary preferences, pest control efforts can be effectively targeted to disrupt their feeding sources and reduce populations.
