How to Get Rid of Silverfish

What are Silverfish?

Silverfish is the name given to a shiny silver insect with metallic scales. The oval-shaped, flat critters run fast giving the illusion that they are swimming. That, along with their minnow-like appearance, has led to their name, Silverfish. They are wingless creatures with two antennae and a three-pronged tail. Because of this tail, they are also known as “bristletails”.

Silverfish prefer moist, dark areas and will usually avoid direct sunlight. Therefore, they are most commonly found in dark corners, sinks & bathtubs, unused spaces, and not frequently accessed storage areas. They are exceptionally long-lived for insects, sometimes living up to eight years. They can also survive a long time without food (up to a year), which can make eradication by bait or poison difficult. Silverfish are bashful of humans and tend to hide their presence so their damage can sometimes go undetected for quite a while.

Are silverfish harmful?

While no one likes the idea of sharing their space with creepy crawlies, Silverfish are relatively benign bugs. They aren’t known to carry contagious diseases, sting, or bite. However, they can contaminate food if they crawl into your pantry, their poop can leave stains, and maybe most concerning, they can eat many things in your home.

What causes silverfish to infest your home or business?

Silverfish are particularly attracted to glue, paper, linens, and moisture. If you have a leak, you will likely find silverfish are soon to follow. Their love of starch means they are frequently found in libraries, personal paper storage, businesses, and pantries.

How do you rid yourself of silverfish?

  1. Dehumidify. One of the first things to do if you have a silverfish infestation is to determine if you have undue moisture. Resolve the cause of that moisture and you are well on your way to solving the problem.
  2. Insecticide. This is an option that can be used. However, as mentioned above, silverfish are not necessarily attracted to bait. They can go a long time without eating so it may be ineffective.
  3. Natural Methods. You could try diatomaceous earth which dries them out and discourages them from returning. 
  4. Professional pest control. You could also seek the experts at Cascade Pest Control to eradicate your silverfish infestation.

How do you prevent silverfish?

Once you’ve got the silverfish under control, you want to make sure they don’t return. Take these precautionary measures. 

  1. Prevent access to your home. Seal up holes, cracks, and other access points.
  2. Prevent moisture. Quickly fix leaks, drips, and humidity issues, especially in areas that are less frequented. 
  3. Prevent access to a food supply. Seal food, reduce dust, and throw out unneeded paper. All of these are things that can attract silverfish.
