A simple household method for dealing with tiny insects in the bathroom is gaining attention: using an ordinary potato. The approach requires no chemicals and can easily be tried at home, according to the outlet unian.net.

Why a potato attracts the insects

Silverfish are small, almost unnoticeable insects. They are mostly active in the evening and at night, which is why they are most often spotted in the bathroom or toilet at those hours. They feed on foods containing starch and sugars, so a potato may look appealing to them.

How to make the trap

  1. Cut a potato in half.
  2. Make a hollow about one centimetre deep in the middle of one half.
  3. Place the potato in a corner of the bathroom and leave it overnight.

The starch and the smell may lure insects, which can crawl into the hollow. To make collection easier the next morning, a sheet of polyethylene film can be laid under the potato, so that both the potato and the insects can be removed together. The method can be repeated for several days in a row.

It does not replace cleaning

One advantage of the method is that it needs no chemicals. Experts nevertheless point out that such a trap does not replace regular bathroom cleaning. Silverfish can also feed on soap residue and other organic matter found in a bathroom. To reduce the chance of them appearing, it is important to keep the room clean and dry.

Particular attention should be paid to humidity, since the bathroom is one of the places in a home where conditions suit silverfish especially well.
