What are Silverfish and Where Do They Come From?
Being such picky about their food, they will not do much harm or damage to your home but they are still a nuisance. Silverfish are quite fast and move around the house a lot, but generally, they will not be in your way. But this makes them hard to exterminate. Because applying insecticides to an area where you’ve noticed silverfish does not guarantee you that they will go there again.
Silverfish are shaped like teardrops, with three bristles on its rear, and can reach up to 19mm in length. The most common colours they can be is either blue and silver, or brown with some grey.
Silverfish can thrive in a variety of climates but where they thrive are dark and damp areas. As already mentioned, they live indoors, which means that the places they are most likely to infest are your attic, basement, bathroom, garage. They seek boxes, paper, damp clothing.Some of the things they can feed on in your house are: wallpaper, papers, cardboard boxes, the glue in books, linen, other small dead insects, foods rich in carbohydrates.
Sings of silverfish infestation
As soon as you spot one silverfish, that means there are more. But of course, they may be an infestation without you seeing an individual. Sings that can tell you have a silverfish infestation are the following:
- Cracks and crevices – you may notice an increase in gaps and holes in skirting boards, window sills.
- Shed skin – as the silverfish life cycle progresses, they shed their skin. At the nymph stage, they are more likely to shed skin and the places where you can easily see it is the bathroom or the kitchen. But since it doesn’t happen in big quantities, the shed skin often gets mixed with general dust and dirt on in the house and goes unnoticed.
- Yellow stains – this can be seen in places the silverfish have been passing through. Yellow stains can be found on books or near them, on papers, wallpapers, even your clothing, if you see such mysterious yellow stains appearing, be sure that there are silverfish involved.
- Damages – since this type of pest feeds on adhesives and glue, you will see holes in places such as storage boxes and papers, wallpapers, books, linen, also they may attack your food- cereal, oats, flour.
- Droppings – this is the sign of most pest infestations. With silverfish, their droppings are rather characteristic and can help determine if it is silverfish. Their faecal matter is black and spherical, looks like pellets, or pepper. You can find droppings near boxes or food or even books.

Do Silverfish Bite?
Do Silverfish Bite People?
Silverfish, even though considered by some to be poisonous centipedes, are not dangerous at all. They are neither poisonous nor do they carry diseases. And they do not seek people to bite them. They are more scared of people than people are of them, and will hide if they are disturbed.
Silverfish can move fast and hide in the smallest crevice where a person will not reach it. Usually, they are active at night and they come out in the search for food and they stay away from people.
Even if it happens that a silverfish bites you, they are harmless.

What Keeps Silverfish Away?
Best Silverfish Prevention & Control MethodsLower humidity levels
Silverfish can survive up to a year without food as long as they have water. Water is essential for their survival and cutting them off will decrease their population a lot. So, remove water sources by fixing leaky faucets or pipes, and closing drains. Keep bathroom well ventilated so it doesn’t stay wet and moist for a long time.
Keep the house clean. Do not store a lot of papers, letters, books in a place where no one touches them or cleans them. Vacuum and sweep your home regularly. Remove wallpapers if you have any. The silverfish are attracted to the wallpaper glue and will destroy your wallpaper to eat it.
Fix small cracks and crevices in walls or floor, or near doors because they make for perfect hiding places and for perfect nests to lay eggs.
But, if you are already struggling with a silverfish problem, hiring a pest control expert will be the most effective way to get rid of them.
