Bed bugs don’t live on your body. Unlike lice or ticks, they feed for 5 to 10 minutes and then leave, retreating to cracks, crevices, and hiding spots near where you sleep. If you’ve found a bed bug crawling on you, you can simply brush it off and kill it. The real challenge is making sure you don’t carry any hitchhikers home in your clothes or belongings after being in an infested space.
Why Bed Bugs Don’t Stay on You
Bed bugs are not body parasites. They don’t burrow into skin, nest in hair, or cling to you the way lice do. A bed bug will crawl onto exposed skin, insert its mouthparts, feed until full, and then immediately return to its hiding place. That hiding place is almost always within a few feet of where you sleep: mattress seams, headboard joints, baseboards, or furniture cracks. They aggregate together in these spots during the day and come out at night to feed.
This means the odds of a bed bug staying on your body for more than a few minutes are very low. If you see one crawling on your skin, pick it off, crush it, and dispose of it. There’s no need for special removal techniques like you’d use for a tick. A shower with regular soap will wash away any stray bug that hasn’t already left on its own.
Decontaminating After Exposure
The more pressing concern is what happens after you’ve been in an infested room, whether that’s a hotel, someone else’s home, or a workplace. Bed bugs can hide in clothing folds, shoe seams, bags, and personal items. Getting them off your body is simple, but keeping them out of your home requires a few deliberate steps.
Before you enter your home, strip off the clothes you were wearing and seal them in a plastic bag. Don’t carry them through the house loose. Put everything, including shoes, into the dryer on medium-high or high heat for at least 30 minutes. Temperatures above 122°F kill bed bugs at every life stage: adults, nymphs, and eggs. Washing clothes in hot water works too, but the dryer alone is sufficient if you’re just trying to kill hitchhikers without doing a full wash.
Inspect your bag, backpack, or suitcase before bringing it inside. Check seams, zippers, pockets, and any folds where a small insect could tuck itself. If you find bugs, seal the bag in plastic and either treat it with heat or leave it outside until you can. A vacuum can help remove bugs from items that can’t go in a dryer, but seal and discard the vacuum bag immediately afterward.
Treating Bites on Your Skin
Bed bug bites typically appear as small red welts, often in lines or clusters on areas that were exposed while you slept. They can take hours or even days to show up, so you may not notice them right away. Some people barely react at all, while others develop intensely itchy, swollen bumps.
For most people, basic care is enough. Wash the bites with soap and water, and resist the urge to scratch. Scratching is the main risk factor for secondary skin infections. An over-the-counter anti-itch cream containing hydrocortisone can reduce inflammation, and an oral antihistamine can help if the itching is widespread or keeping you awake. In more severe reactions with significant swelling, a doctor may prescribe a stronger steroid cream. Antibiotics are only necessary if scratching has led to an infection, with signs like increasing redness, warmth, or pus.
Essential Oils Won’t Protect You
Dozens of essential oil products claim to repel or kill bed bugs, but independent testing tells a different story. A Rutgers University study found that few of these products actually work against bed bugs. Purdue University researchers identified compounds in oregano, thyme, lemongrass, and clove oils that can kill bed bugs on direct contact, but the most effective natural compound still required roughly 70,000 times more product to kill a bed bug than a standard synthetic insecticide. Rubbing essential oils on your skin before bed is not a reliable way to prevent bites or keep bugs away.
When the Crawling Feeling Won’t Stop
Many people who’ve dealt with bed bugs report a persistent sensation of something crawling on their skin, even after the infestation has been treated or they’ve left the infested space. This is a real neurological phenomenon called formication. Your brain’s touch-processing areas can generate signals that feel identical to insects moving across your skin, even when nothing is there. These sensations feel completely real and can be difficult to distinguish from an actual bug.
This is common and does not mean you’re still infested. The anxiety and hypervigilance that come with a bed bug encounter can prime your brain to interpret every minor itch, hair movement, or clothing shift as a crawling insect. If you’ve taken decontamination steps and a professional inspection confirms no active infestation, the crawling sensation is very likely your nervous system on high alert. It typically fades as the stress of the experience subsides. If it persists for weeks or becomes distressing, a healthcare provider can help.
The Real Problem Isn’t Your Body
Because bed bugs don’t live on people, getting them “off your body” is the easy part. The harder problem is your environment. If you’re waking up with new bites, the bugs are in your mattress, furniture, or walls, not on you. A hot shower and a change of clothes will handle your body. Eliminating an infestation in your living space almost always requires professional pest control, as bed bugs are resistant to most consumer insecticides and can survive months without feeding while hiding in spots you’d never think to check.
