What Do Baby Silverfish Look Like?

Baby silverfish,or nymphs, are very small, usually around 1/16 of an inch long. The insects do not undergo metamorphosis, so young silverfish are similar in appearance to adults with their lengthy antennae, six legs, and three long posterior appendages.

Until they develop their characteristic silver scales after going through four molts, silverfish nymphs have soft, white bodies.

Silverfish Life Cycle
It takes approximately 40 days for them to develop into mature adults, though, where environmental conditions are unfavorable, the process can take over a year.

Adult silverfish live up to three years in the right conditions.

Damage Caused

Baby silverfish inflict damage similarly to adults as they also feed on proteins, starches, and sugars.

They are just as capable of damaging paper and clothing products and are more likely to contaminate stored foods like:

  • Cereals
  • Grains
  • Flours

As they eat, silverfish nymphs chew ragged holes in:

  • Pages of books
  • Curtains
  • Carpets
  • Wallpaper

Fabrics such as rayon, cotton, linen, and silk can be riddled with holes given infestations of baby silverfish.

Homeowners may notice a yellow discoloration on pages of books where young silverfish have fed.

Responding to Signs of Infestation

Growing Populations
Where silverfish nymphs are present, adults are also likely to exist in abundance. Females lay an average of 50 to 60 eggs per mating period, and eggs can hatch in as little as 19 days. As such, populations of the pest grow rapidly.
