Of all the common household pests you can encounter, silverfish are one that you generally don’t want to see. They multiply rapidly, contaminate food, and thrive in hard to reach places like cracks and crevices, or behind baseboards. Additionally, they reproduce at an insane rate and live for up to eight years!
Eliminating silverfish infestations is rather simple with the proper use of insecticide sprays, bug traps, and powdered repellents. However, with the vast array of products available on the market these days, making an informed decision about a product is not always a simple task.
This article aims to cut through all the chatter and bring you the information you need to select the right product for your home or office.
Why You Should Eliminate Silverfish in Your Home Today
Silverfish are primitive wingless insects who have slender, flat bodies that are covered with silvery scales that usually have a metallic sheen. Their body tapers gradually towards the rear, giving them a fishlike appearance — hence their name.
Likewise, their scientific name, Lepisma saccharina, offers some insight into their eating habits. Silverfish are voracious eaters that consume a variety of different foods. However, they prefer eating carbohydrates and proteins.
They can be quite destructive with their habit of eating book bindings, cereals, glue, paper, and photographs. They have been observed tearing off wallpaper so they can get to the paste holding it up so they can eat it.
Additionally, they consume starch found in clothing, cotton, linen, and rayon fabrics. In the kitchen, they like eating cereals, dried meats, and wheat flour.
With that kind of appetite, one can easily understand the importance of getting rid of them as quickly as possible. However, that can be easier said than done as silverfish like to live in the deep dark recesses of people’s homes.
For example, they like cold and damp places (they thrive in humid environments) like basements and laundry rooms. Likewise, they like getting into cracks and crevices, and are known to get beneath hardwood flooring and behind baseboards. Even worse, they can live up to a year without eating as long as they have access to water.
Moving along, we will cover using sprays, glue traps, and powdered repellents to eliminate silverfish and other similar indoor pests.
Using Sprays to Get Rid of Silverfish
The most common type of insecticide and repellent for silverfish comes in the form of liquid sprays. As an added benefit, if you spray the perimeter of your home or business, liquid sprays can create a barrier around your house or business and prevent an infestation in the first place.
However, some sprays are difficult to handle and require the use of special high-pressure sprayers for maximum efficiency.
On the negative side, persistence is usually only a few days to a few weeks. Furthermore, you must keep small children, pets, and livestock away from many liquid sprays until the surfaces fully dry.
For that reason, extra caution is recommended when using liquid sprays. If you have any questions about a product’s safety, be sure to read its label and contract the manufacturer as needed!
As always, if you aren’t experienced, please contract your local pest control or wildlife specialist to make sure sure things are done correctly.
Using Glue Traps to Get Rid of Silverfish
Another popular method of controlling silverfish is the use of glue traps. Also known as glue boards, glue traps are cardboard trays or boxes coated with an extremely sticky adhesive substance.
Insects that touch a glue trap are immediately stuck to the board and can be eliminated when you replace the trap with a new one.
Glue traps have the benefit of lasting a long time, with some of them lasting upwards to a year. Additionally, they are safe for use around small children and pets.
However, glue traps typically work best when used alongside liquid sprays or powdered repellents.
Using Powdered Repellents to Get Rid of Silverfish
Powdered insecticides and repellents are less conventional than liquid sprays. However, they offer plenty of benefits.
For example, they typically last for several months making far more effective than sprays. Additionally, many powdered insecticides are safer for around the house use.
On the negative side, the application of silica gel additives is necessary to help powdered insecticides stick to windows, doorways, and other portals into your home.
Selecting the Best Product for Combatting Silverfish
There are a variety of different factors to consider when selecting the best products for eliminating silverfish. For example, the overall safety of a product is paramount. This concern for safety is particularly crucial if there are small children or pets in the home.
Next, you should research the coverage provided for each product and how long it lasts. Some products like liquid sprays last for weeks, while powdered insecticides and repellents can last for several months.
Then, you should consider the product’s ease of use. For example, some liquid sprays are cumbersome and awkward to use. Inversely, the most challenging aspect of using glue traps is deciding where to place them.
Is the Spray, Trap, or Repellent Safe?
Safety is perhaps the most critical factor to consider when purchasing an insecticide or repellent. This concern is particularly essential if you have children or pets.
For that reason, you should take the time to read all the instructions on the product’s label and any accompanying documentation. Likewise, take the time to familiarize yourself with the three standardized signal words used on the labels of insecticides and repellents.
You should review these 3 key symbols from the National Pesticide Information Center before purchasing a spray, trap or repellent.
Always remember to keep your pesticide and insecticide treatments out of reach where only you can get it. Keep things sealed and secure. It’s very important!
Along those lines, it is always a good practice to only purchase the amount of insecticide or pesticide needed. Doing so eliminates the need to store those products in the first place.
What Is the Insecticide or Repellent’s Coverage Area?
Concentrated liquid sprays provide the best coverage, particularly if your goal is to prevent silverfish from entering your home or office in the first place.
Powders are a close second when it comes to coverage, and glue traps offer negligible coverage.
How Long Does the Insecticide or Repellent Work?
Most liquid sprays remain active for a few days to a few weeks at best. On the other end of the spectrum, powdered insecticides and repellents can last for several months, and in some instances, as long as a year.
Theoretically, glue traps can last as long as a year, but if you have any pests in the home, you will likely need to replace them every few weeks.
Additionally, if you plan on needing to place anything outside, please keep in mind that rain could potentially wash away your treatment.
Is the Insecticide or Repellent User-Friendly?
When it comes to being user-friendly, glue traps can’t be beaten. You open up the package and place them around your doorways, windows, and any areas where you think silverfish might be lurking.
Likewise, powdered insecticides and repellents are relatively easy to use. For example, they are lightweight and typically don’t require the use of any special equipment.
Liquid concentrates and sprays are the most difficult products to use by a long-shot. They are cumbersome, and frequently require the use of high-pressure sprayers. Additionally, they tend to be messy, requiring substantial clean up if you don’t use them carefully. Storage can also be an issue with liquid sprays.
