The answer to 'types of silverfish' is that there are several common species of silverfish that can infest homes. Silverfish are small, wingless insects that are typically silver or gray in color and have a distinctive fish-like shape and movement. The most common types of silverfish found in homes include the common silverfish, the gray silverfish, and the four-lined silverfish.
Silverfish are primarily nocturnal and prefer damp, dark, and undisturbed areas of the home like bathrooms, kitchens, and basements. They feed on a variety of materials including paper, fabrics, and starches, and can cause damage to household items if left unchecked.
