Do silverfish go away in winter?

Do silverfish go away in winter? Silverfish do not go away in winter on their own if indoors, as they live indoors in heated homes where conditions remain suitable year-round, especially in damp basements and bathrooms. Outdoors, silverfish may be less active in cold winter as they prefer warm temperatures 70 to 80 degrees Fahrenheit, but indoors they can remain active throughout winter if humidity remains high and food sources like paper and glue are available. They are nocturnal and can survive months without food, so they can persist through winter in wall voids, attics, and basements. Cold temperatures below freezing can kill them if exposed, but indoor heating protects them. So silverfish do not go away in winter indoors, they remain active, though you may see them less if home is drier in winter due to heating. To eliminate in winter, continue moisture control with dehumidifier, cleaning, sealing cracks, and using traps and insecticides, as winter does not eliminate indoor infestation without intervention.
