McDuffie Silverfish pic-1


Silverfish are small wingless insects that are mostly a light grey and blue color; it has the word “fish” in its name because of the way that it moves. They are nocturnal insects that usually grow to be about 0.5-1 inch long. When they are first born they are more of a white color and as they get older they get the blue and grey color to them.Silverfish tend to live from two to eight years.


Silverfish are an extremely common household pest. They are known as “bristletails” as they have three long bristle-like “tails” on the end of their body. They range anywhere from twelve to nineteen millimeters and are typically a silvery grey blue to a brownish red. They have six legs and a lengthy pair of antennae with an elongated body that is oftentimes described as carrot or teardrop shaped. While their namesake refers to their fish like body style and movement, they also have a series of scales running down their body to serve as protection from predators and the elements. 


Silverfish tend to try and hide away from humans and are very skittish. While you may think “out of sight out of mind” silverfish can cause a plethora of damage which goes unnoticed by a majority of homeowners.


Silverfish can typically be found in moist and humid areas of the home. They love to nest in basements, attics, and more commonly, bathrooms. A common place silverfish have been discovered is coming down through ceiling soffits and light fixtures in ceilings. Silverfish are very slippery so it is important to keep an eye out for any signs of infestation.


The most important thing to do for silverfish control is thorough inspection. Identify the possible silverfish habitats around your home and keep a close eye on any signs of damage. Be on the lookout for feeding marks, notches along an edge, or surface etchings. Another telltale sign of an infestation will include yellow stains, scales and/or feces throughout feeding sites. Dehumidifiers can also act as a line of defence against silverfish as well as properly maintaining the plumbing and drains around your home. There is nothing a silverfish loves more than a wet humid place to breed.
