The answer is: probably not.

While the services likely do what they say they do - which is kill dust mites and eliminate their allergens - experts believe that the dust mites will return to their former levels in a couple of months.

Companies that offer this kind of service usually recommend twice a year cleaning - which means that you’ll be living with your regular level of dust mites for at least 8 out of 12 months.

What do these services do to kill dust mites? In most cases, they use steam cleaning. Sometimes they also employ ultraviolet light. Pediatric allergist and professor emeritus, Peyton Eggleston, says that both methods will kill mites - but only in the short term.

If you’ve got your own steam cleaner at home, you can likely kill off mites yourself. A better bet is a mite-proof cover for your mattress and key bedding items, like pillows. Wash bedding frequently in hot water to ensure no mites in items like duvets or comforters.
