Bed Bugs After Travel: What to Do When You Get Home

The ideal practice feels extreme, but it genuinely works: don't bring luggage inside the moment you get home. If you can, leave it in the garage or on a hard-surfaced area outside (not in the yard, where it can pick up other pests) while you inspect. Hard, sealed surfaces give bed bugs nowhere to hide and make a visual inspection far more effective.

Inspect the seams, pockets, and exterior surfaces of each bag carefully. Use a flashlight to check inside dark pockets and seams. Bed bugs at this stage may be adults (apple-seed sized, reddish-brown) or nymphs (smaller, translucent to pale yellow). Look also for fecal spots (tiny dark dots) and shed exoskeletons.

All packed clothing, worn or not, should go straight from the luggage into the dryer on the highest heat setting for at least 30 minutes before it's washed. The sequence matters: dryer first, then wash. Washing alone doesn't reliably kill bed bugs, because the water in most home washers isn't hot enough. High dryer heat (above 120°F) kills bed bugs and their eggs at every life stage.

Items that cannot be put in a dryer should be inspected carefully and either sealed in a plastic bag for several days (bed bugs can survive without feeding for months, so this is not a definitive kill method but reduces immediate spread risk) or treated with a specialized travel bed bug spray. Consult the CDC and EPA for guidance on products that are evidence-based for this use.

After removing and laundering all contents, inspect the luggage itself. Use a flashlight to examine all seams, pockets, and interior lining. Pay particular attention to the corners, the area around zippers, and any fabric lining tacked to the interior frame. Bed bugs can flatten themselves enough to hide in very thin seams and crevices in luggage frames.

Hard-shell luggage with fewer seams provides fewer hiding places than soft-sided bags with multiple pockets. If you travel frequently, hard-shell luggage is preferable from a bed bug standpoint. After inspection, store luggage in sealed plastic bags or storage bags in a location away from sleeping areas, such as a garage or storage room.

In the days to weeks following travel, watch for: small red or brown spots on bedding or mattress seams, a faint sweet or musty odor in the bedroom, unexplained itching welts that appear in lines or clusters on skin exposed during sleep (though not everyone reacts to bed bug bites), and shed exoskeletons or fecal spots in mattress seams or on box spring fabric.

Note that bites alone aren't a reliable indicator, because up to 30% of people show no visible reaction to bed bug bites. Physical evidence in the sleeping area is more reliable than bite reaction. Interceptor devices (plastic cups placed under bed legs that trap bed bugs as they try to climb up or down) are an effective early detection tool. Place them right after returning from travel if you have any concern.

Preventing introduction starts before you return home. The EPA recommends a brief inspection of hotel sleeping areas on arrival: pull back the bedding and check the mattress seams and box spring, especially at the corners. Check the headboard surface closest to the wall. Look in the nightstand drawer. If you find evidence of bed bugs, request a different room and ask that it be several rooms away. Bed bugs can migrate through wall voids in hotels.

Do not place luggage on the bed or upholstered furniture. Use the metal luggage rack (inspect it first) or keep bags on the bathroom tile floor, which is easier to inspect and less likely to harbor bed bugs.
