Silverfish are a flat bodied, silvery scaled insect that are common in most households. They are starch and sugar eating bugs, which is one of the reasons they are often found between the pages of books. Their thin and tapered bodies are perfectly adapted to fit inside of book pages, and their starch fueled appetite will eventually cause considerable damage to both the binding, where the glue is, and the wood-pulp manufactured pages themselves. They also like damp places, and will feed on mold and fungi, which means they are also commonly found in bathrooms and laundry rooms too. Although they do not carry diseases and would rather stay hidden, they can become a true pest if their numbers become high enough. Fortunately, their are some good silverfish killers available that will effectively eradicate them.
Effectiveness and ease of use make it on to this list, but the best silverfish killer in 2022 will be safe to use in an organic formula.
