If we were to spring clean with the goal of making life difficult for bacteria in our home, we’d probably start with commonly thought of as trouble spots like the toilet or where we put the bin. But perhaps we would risk omit apparently “innocent” corners, which they hide instead many more unwanted guests than we might expect. Here are ten and more of the dirtiest in our homes: from cushions to the make-up bag. According to a study by the Food Safety and Inspection Service of the United States Department of Agriculture (FSIS), more than 200,000 different species of insects, bacteria and fungi live in our homes. And although most of them are basically “harmless” to humans, others may not be so “friendly”.
