Keeping a good hygiene in your home is essential and can be rewarding. There are numerous kinds of insects that can hatch and make a home inside your home.

Insects such as silverfish can be a terrifying thing to deal with and it is better to prevent it instead of finding a solution to kill them.

However, sometimes you can be too late, and it maybe won’t be your fault, but you will need to react immediately.

Silverfish are always attracted to places that are dark and wet, such as basements, bathrooms, and kitchens. Even though they are harmless, you don’t want to have them as pets in your home.

They feed themselves with sugar, starches, paper, shampoo, dead insects, silk and books. Because they are small, they can slip in food packages that are not even opened.

Silverfish have the form of a tear and have long antennae and three bristles. They can be silver or brown-grey and have three pairs of legs. One female can lay between 2 to 20 eggs and usually they position themselves in small holes or gapes.

After being laid, they can hatch their eggs for 19 to 60 days and it all depends on the moisture in the area. One silverfish needs around three months to become mature and it can leave up to three years.

To check if your home is infested, look for yellow spots on places such as kitchen table, papers, eggs, and food containers. If you notice small black feces, you need to react immediately.
