Some doormats placed near the front door can do more harm than good.
Biotechnologist Maria Zolotareva shared a comment on this topic.
In a conversation with Gazeta.Ru , the expert explained that these rugs often create an environment for the growth of bacteria and mold.

This primarily concerns products made from cotton and wool.
The biotechnologist advises using synthetic rugs. They are less likely to cause mold in the home.
Rugs made of any material should be regularly cleaned or washed, and treated with an antiseptic before use.
And it's not just about germs and mold.
Door mats "collect" everything that is brought in from the street. For example, allergens (pollen, hair) and other small debris.
The expert also noted that accumulated dirt can be a source of helminths.
This is something that cat and dog owners should remember first and foremost.
