There could be a tiny silver insect lurking in your home that could lead to a very expensive problem if you're not careful.
Silverfish are strange, shiny silver (hence the name) insects, shaped almost like a teardrop (and you might shed a tear if you find some in your home).
The insects are harmless to humans and they themselves don't damage your house. It isn't the insects themselves that are the problem and you don't need to kill them.
