The five-second rule is a myth: bacteria can live after four weeks on carpet.

Bed bugs can live in carpet fibers and wooden floorboards. For their size, they are extremely fast and can crawl more than 100 feet to obtain a blood meal, usually at night from people who are sleeping. Engorgement takes about three to 10 minutes yet people rarely realize they are being bitten._[4]
A person sheds about 1.5 million skin flakes an hour, most of which becomes embedded in our carpets._[12]
Scientists believe that more than 43 million tons of dust falls over the U.S. every year. Indoor air usually contains about twice as much dust as the air outside. That’s a million microscopic particles in a cubic inch of air. About 2,000 dust mites can live happily on one ounce of carpet dust._[2]
Wall-to-wall carpeting is less healthy than smaller rugs because wall-to-wall carpets tend to be more permanent and harder-to-clean endpoints for moisture, chemicals, liquids, crumbs, and other spills that provide molds, mildew, yeasts, and bacteria (such as e-coli) with a rich and nearly continuous supply of nutrients._[16]

Currently, evidence for a causal link between the disorder and carpet cleaning is inconclusive._[1]
Dust mites thrive in warm, humid environments, eating dead skin cells and nesting in dust-collecting carpet. The residue that mites leave behind can mix with dust and become airborne, which may cause allergies._[15]
All carpet should be professionally cleaned a minimum of every 12 to 18 months._[13]

New carpets can be a source of chemical emissions. Customers should ask retailers about selecting lower-emitting carpet adhesive or about airing out the carpet before it is installed._[16]
