Silverfish aren't the worst pests to have in your home, but you still don't want them there. Fortunately, you can simply trap these bugs using powdered oatmeal.
Pour some powdered oatmeal into a jar and place a piece of tape vertically down the side of the jar to give them an easy path to walk up and into the jar.
They will gravitate toward the jar and make their way into the oats to eat. However, once they climb in, the powder from the oats will prevent them from being able to climb out.
