Ctenolepisma longicaudata Escherich

[Thysanura: Lepismatidae]



Adult: Silverfish are approximately 15 mm long. The body is elongate, tapering rearward and dorso-ventrally (top to bottom) flattened. Ctenolepisma longicaudata is covered in scales which are predominantly silver-grey and not banded.

Head: Silverfish have compound eyes and long filiform antennae (longer than the body). Maxillary palpi are 5-segmented and mouthparts are covered with a beard (a row of setae).

Thorax: Silverfish are wingless.

Abdomen: Abdominal segments 2-6 are covered in scales and barbed setae that are arranged into 3 pairs of combs. Three abdominal appendages are present. Silverfish have a pair of cerci and an appendix dorsalis. The cerci and appendix dorsalis are longer than the abdomen.


Reproduction& Life-cycle:Females lay up to 50 eggs in batches on 2-20. Eggs are ovoid, 1 mm long, cream-coloured and placed in crevices during summer. The eclosion period is 3-7 weeks. Nymphs are similar to adults in appearance and undergo 15 moults. Nymphal development is 2-3 years. Silverfish continue to moult as adults and live for up to 4 years. Adults can survive for approximately 9 months without food.


Distribution:Ctenolepisma longicaudata is a common pest in eastern Australia.

Pest Status:Silverfish feed on paper, starch and fabrics in urban habitats and are potentially a serious pest in libraries.

"We first used A1 Pest Control a few years ago when we noticed a few termites under a wine barrell in the rear yard of our home. We asked A1 Pest Control Sydney to pay us a visit to have a thorough termite inspection of our home. Bruce and his crew were on time, and very well presented. They explained how they would get rid of the termite infestation using a low toxic method and how their Thermal cameras worked, It worked very well and now we can sleep at night!"

"We have been using Bruce form A1 Pest Control for over 4 years now. We bought our new house on the Hills Area, and moved in. our neighbours had problem with rodents and spiders so they are using A1 next door. I asked them if they could come over and treat our house too, as i didn't want to chase pest around our home. The service was not only effective, but carried out without any smelly fumes that we have experienced in our last house. They solved problem next door and I haven't seen a bug since."

"A1 Pest Control exterminators where great! I'm very happy to say that they solved a bed bug problem that I had after we had visitors from overseas visit us. I would recommend A1 Pest Control to anyone needing a safe and effective treatment of bed bugs"

"Bruce solved our commercial pest control problem in Castle Hill. Cockroaches were throughout our factory and they were completely gone after two visits from his exterminators. Just seeing one cockroach can lose us clients. I know now everyhing is ok, and our reputation is intact"

"Bruce from A1 Help us get rid of a bad spider infestation that have been troubling us for a while. It was done with low toxic spray and his crew even game me some cockroach and ant baits to get rid of them. I have recommended A1 to all my friends and family"
