Health Risks of Staying in a Stranger's Home

Bed bugs, allergens and other hazards of staying with strangers.

Hosts who register with these sites are given hospitality standards and responsible hosting guidelines to follow, and user reviews can alert guests to potential dangerous or unsanitary situations before they book. Airbnb, the largest vacation-rental website, also recommends that hosts keep a first-aid kit in their house, and will require that all units confirm they have working smoke and carbon monoxide detectors by the end of the year.

But rentals are rarely inspected by the companies that list them, and it’s up to each host to ensure that standards are met. And no matter where you go, being away from home always entails some degree of health risks, especially during the busy winter travel season, says Edwidge Thomas, nurse practitioner and director of clinical practice affairs at the New York University College of Nursing. Here are six common risks to look out for, and how to safeguard against them.

10 Biggest Myths About The Flu

Some rental hosts even leave food for their guests, or instructions about which items and ingredients in the fridge or pantry are up for grabs.

“But before you take anything, check expiration dates first,” says Thomas; “and make sure perishable foods look and smell okay.” It’s also important to be sure the refrigerator is kept at the right temperature—at or below 40° Fahrenheit, with the freezer at or below zero degrees—and that it appears clean and free of bacterial growth.

“I have clients who always travel with their own sheets and towels because they just feel more comfortable knowing how and when they’ve been washed,” says Thomas. “If they’re worried about waking up with a rash or itchy skin, it’s a good precaution to take.” People with pet allergies or asthma may want to confirm before arriving that there is no pet dander, cigarette residue, or other potential triggers in the home, as well.

So anywhere you’re sleeping in a bed that’s not your own, it’s smart to be on the lookout. These critters can hitch a ride to other homes in travelers’ suitcases, so the more people passing through a rental apartment or a friend’s guest room, the greater the chance that someone brings along the unwanted companions.

Protect yourself in someone else’s home the same way you would in a hotel: Keep your luggage off the ground and the bed during your stay, and inspect the bed upon arrival. Pull back the linens and check under the mattress and behind the headboard for blood stains, small black dots, or the bugs themselves, which are about the size of an apple seed.

15 Tips for Avoiding Hotel Bedbugs

Give the bathroom a good safety inspection, as well. Can you climb in and out of the bathtub easily? Is there a mat on the floor to keep you from slipping with bare feet? (If not, put a towel down.) Some rental services, like Airbnb, ask hosts to ensure their properties are free of such hazards, that stairways have railings, and that potentially dangerous areas are clearly marked—but it still can’t hurt to be extra cautious while you’re getting the lay of the land.
