Recent studies have shown that dead cockroaches and their residuals in homes can cause asthma. About 30 to 40 percent of the infections inside your home are transported out of the outside environment.

They can enter through your footwear, your clothes or your paws and hair of your pets.

Children are at greater risk of exposure to dust contamination since they sit and swing on the floor and put their hands in their mouths.

Many studies confirm that the greatest number of environmental exposure and risk, especially for young children, arises within homes.

Children are not the only ones at risk of infection but also anyone suffering from asthma or other respiratory problems or a weak immune system.

With the first four steps within your home you carry about 85 percent of the outside environment infections within your home.

By taking some simple steps you can upgrade your home health and reduce the cleaning time of your home.

Place entrance mats on each external entrance and even the entrance between garage and house if any.

EPA (Environmental Protection Agency) recommends adopting an entry system that will trap soil, contamination and moisture at the entrance.

Place a hard mat outside the entrance for scratching your shoes before entering the house.

Inside the house place a highly absorbent mat that will trap the dust and moisture at a lower level of the shoe.

If there is space, it is good to place another mat to retain any dust and moisture remaining at the bottom of your shoes.
