Silverfish are creepy little insects that are often found in dark, damp areas of your home. They are usually harmless, but they can be a major nuisance if they start to invade your living spaces. If you are wondering what attracts silverfish to your home, there are several factors that could be contributing to their presence.


One of the most common reasons why silverfish are attracted to homes is because of moisture. These insects thrive in damp environments, so if your home is humid or has poor ventilation, you may find silverfish crawling around. Moisture can come from a variety of sources, including leaky pipes, wet basements, and even condensation on windows. To reduce moisture levels in your home, try using a dehumidifier or fixing any leaks as soon as you notice them.

Food Sources

Silverfish are scavengers that will eat just about anything they can find. They are particularly fond of starchy substances like paper, glue, and fabric. If you have stacks of old newspapers or cardboard boxes lying around your home, you may be inadvertently providing silverfish with a steady source of food. To reduce the chances of attracting silverfish with food sources, store paper goods and fabrics in sealed containers.


Silverfish love cluttered areas where they can hide and breed. If your home has piles of clothes on the floor or stacks of books on the shelves, you may be providing silverfish with the perfect environment in which to thrive. To reduce clutter and discourage silverfish from taking up residence in your home, try to keep things organized and tidy.

Cracks and Crevices

Silverfish are tiny insects that can squeeze through even the smallest cracks and crevices. They often enter homes through gaps around windows and doors or through holes in walls or floors. Once inside, they can quickly multiply and spread throughout your home. To prevent silverfish from entering your home, seal any cracks or gaps around doors and windows with caulk or weatherstripping.

Lack of Light

Silverfish are nocturnal insects that prefer dark environments. If your home is poorly lit or has areas that are always shrouded in darkness, silverfish may be drawn to those spaces. To discourage silverfish from taking up residence in your home, make sure all areas are well-lit and consider leaving a nightlight on in particularly dark areas.

In conclusion, there are several factors that can attract silverfish to your home, including moisture, food sources, clutter, cracks and crevices, and lack of light. By addressing these issues and taking steps to make your home less appealing to silverfish, you can reduce the chances of an infestation. While silverfish are generally harmless, they can be a nuisance if left unchecked. With a little effort and attention to detail, you can keep these creepy little insects out of your living spaces for good.
