Silverfish are small wingless insects that move quickly with fish-like motion. They are nocturnal and prefer dark humid places, like your basement. You’ve probably been startled by them. But what are they and where do silverfish come from? Watch our video.
No need to fear silverfish bites – beyond their freaky appearance, they are harmless to human beings. We’ll clue you in on these terrestrial shrimps of the cellar world and tell you how to get rid of silverfish. The main problem is their destructive capabilities, and we’ll tell you what silverfish eat in your home.
What Do Silverfish Look Like?
Glad you asked. The video below highlights the characteristics of silverfish along with some nice (safe) close-up footage. Generally, silverfish are about 1 inch long with gray or silver scales along their bodies. They have long V-shaped antennae sticking out from their head and three spiky bristles off their tail.
Silverfish are quite common pests. It’s even possible that they hitchhiked into your home on items that you brought in. More often, they squeeze into your basement through small cracks and gaps in your foundation or around windows.
What Silverfish Eat
Silverfish aren’t picky eaters. They will feast upon any starch protein or sugar they can find and the definition of each gets stretched.
Silverfish commonly will eat paper and cardboard found in your basement. They also like the glue that holds these items together. Other things silverfish eat include textiles like linen and cotton, cereal grains, wallpaper or even carpet.
Baby silverfish are tiny versions of the adult form except for the scales. Babies molt several times before they develop their scales. They eat the same starchy diet that adults do and are nocturnal feeders, like the adults.
How to Prevent Silverfish in Your Home
The way to keep silverfish out of your home is to create an environment they don’t like. This means keeping your basement clean and dry. Run a dehumidifier and fix any leaky pipes that are causing moisture. Seal gaps and cracks in your foundation and around windows where silverfish may squeeze in. Don’t attract silverfish and don’t let them in.
If you’re concerned about a silverfish infestation in your home, call or contact Griffin for real solutions to your pest problems. They may be harmless but that doesn’t mean you want them in your home!
We’ve written about how widely unknown and misunderstood silverfish are before. If that’s true of silverfish, however, it goes double for firebrats. Firebrats are basically silverfishes’ freakier cousin. They look more intimidating, they’re not as common, and you find them in stranger places. If the average homeowner can’t identify a silverfish on-sight, they’ve probably never even heard of a firebrat.
Just like silverfish, however, firebrats aren’t nearly as freaky as they look or sound. Like all pests, they have certain predictable patterns of behavior you can identify with a little knowledge. Once you understand firebrats, you’ll fear them far less. Even better, you’ll know what to do to keep them away from you! Here’s everything you should know about the silverfishes’ heat-loving cousin, and what to do about them.
What are firebrats?
Firebrats and Silverfish are both insects in the Lepismatildae family. Lepismatildae insects are commonly referred to as “bristletails,” because of the three, prong or tail-like bristles on their abdomens. The insects grow to around 12mm (0.4 inches) long, though their bristles and antennae make them appear longer. Bristletails have flat, long bodies with clearly segmented sections. These segments are covered in small scales, giving bristletails an armored appearance.
Firebrats and silverfish are similar in most ways. They’re both nocturnal scavengers, and they both move by running in a distinct, wiggling motion that resembles swimming. There are a few ways to tell a firebrat apart from a silverfish, however. While silverfish are silvery and metallic-looking, for instance, firebrats are darker gray or brown and less shiny. Unlike silverfish, firebrats have tufts of brown scales, which gives them a mottled or spotted appearance. While you’ll find silverfish in any humid area, firebrats prefer environments that are both hot (over 90℉) and humid.
What do firebrats want?
Firebrats enter homes looking for food, shelter, warmth, and humidity. Like silverfish, firebrats are nocturnal foragers. They hide in dark, hot, and humid areas during the day and come out to feed at night. Firebrats are general feeders that break down and consume the starch in a wide variety of material. They can eat wood, paper and paper products, glue, cotton, silk, flour, cereal, and more. Bristletails aren’t particularly picky about what they eat, and generally feed on whatever’s closest to their preferred hiding places.
Firebrats need to live and hide in areas of very high heat. They also prefer humid environments, though they’re more resistant to dryness than silverfish. Firebrats are highly heat-resistant and usually gravitate toward areas that are 90℉ or hotter. You’ll often find them hiding around furnaces, ovens, water heaters, hot water pipes and other heat-generating fixtures. They may also gather around heating vents. If you find a bristletail near a heat source, it’s probably a firebrat.
Where do firebrats come from?
Firebrats are distributed all over the world, and most commonly found indoors. They sneak into homes the same way most nuisance pests do: either through openings, or by hitchhiking on packages. Firebrats have very thin, flat bodies, and they’re very proficient climbers. The insects squeeze their way through very small cracks and crevices in order to get to warm locations. They find these cracks and crevices by following heat sources like utility pipes or drafts.
Firebrats are also very good at hiding. When they find a suitable hiding place, they’ll hunker down in it for hours at a time, until night falls and they can forage. Often, homeowners may inadvertently carry their hiding place into their home–while the firebrat is still using it! Boxes, bags, firewood, linens, and especially heat sources can all harbor firebrats. Inside, they’ll seek out hot and humid hiding places where they can easily access food. If possible, firebrats will stay close to the area where they initially entered your home.
How can I keep firebrats out?
Generally speaking, if you have a bristletail infestation, it’s because there’s too much humidity in your home. That excess humidity could be coming from all kinds of places. If you have a firebrat infestation, specifically, then the source of the problem is probably near a warm place. Start by checking your water heater and hot water pipes for leaking or other damage. Leaking hot water creates the picture-perfect environment for firebrats, and they’ll notice it.
After you’ve checked your water fixtures, expand your search to all heat-generating fixtures. Make sure nothing’s leaking or dripping condensation in your kitchens or bathrooms. Check for drafty openings, especially near your utility lines and window sills. Make sure your attic insulation is doing its job properly, and you aren’t losing heat. You should also consider investing in a humidity monitor and dehumidifier for at-risk areas of the home. Addressing humidity, patching up access points, and removing clutter should all help keep firebrats away.
Despite sounding like some kind of cartoon monster, firebrats aren’t dangerous. They can’t sting, bite, or otherwise harm humans in any way. That doesn’t mean they’re not a problem, however. Firebrats can and will reproduce in your home. They’ll also stain and damage all kinds of food and other materials. You shouldn’t fear firebrats, but you should do all you can to keep them out.
