Most home remedies for bed bugs work best as part of a combined strategy rather than as standalone solutions. No single DIY method will eliminate an established infestation on its own, but several approaches backed by university research can kill bed bugs on contact, contain their spread, and reduce their numbers significantly. Here are 15 remedies you can start using today.
High-Heat Dryer Cycles
Your clothes dryer is one of the most reliable bed bug killers you already own. A loosely filled dryer set on “high” kills all bed bug life stages, including eggs, in 30 minutes. Bed bugs die within 20 minutes at 118°F, and most household dryers on high exceed that easily. Toss bedding, pillows, stuffed animals, clothing, and fabric items from infested areas into the dryer. Don’t overpack it; air needs to circulate for the heat to reach every surface.
Hot Water Washing
Before the dryer, wash infested fabrics in hot water. The key temperature is 118°F or above. Most home water heaters are set to 120°F, so a “hot” wash cycle typically reaches the lethal threshold. Washing alone may not kill every egg, since bed bug eggs need sustained exposure at 118°F for a full 90 minutes to reach complete mortality. That’s why following up with a high-heat dryer cycle is essential.
Steam Treatment
A garment steamer or handheld steam cleaner lets you treat surfaces you can’t throw in the dryer: mattress seams, box springs, upholstered furniture, carpet edges, and baseboards. The target surface temperature should reach 160 to 180°F. Move the steamer head slowly, about 12 inches every 30 seconds, so the fabric absorbs enough heat to kill bugs hiding underneath. A larger steamer head covers more area and delivers more consistent temperatures than a narrow nozzle.
Freezing Small Items
Your home freezer can kill bed bugs in items that can’t tolerate heat, like leather goods, electronics accessories, or delicate fabrics. Place items in sealed plastic bags and freeze them at 0°F for at least three days. If you’re not sure your freezer holds a steady temperature, extend that to two weeks. Flash-freezing at minus 15°F kills eggs instantly, but most household freezers don’t get that cold, so the longer timeline is the safer bet.
Mattress and Box Spring Encasements
Encasing your mattress and box spring in a bed-bug-proof cover traps any bugs already living inside and prevents new ones from getting in. For an encasement to work, it needs to meet specific criteria: the fabric must be bite-proof so bugs can’t feed through it, the zipper teeth must be small and tightly spaced so even immature bugs can’t squeeze through, and the zipper must seal completely at the end with no gap. Once sealed, trapped bed bugs can’t escape or feed, and they eventually starve. Leave the encasement on for at least a year to be safe, since bed bugs can survive months without a meal.
Interceptor Traps Under Furniture Legs
Interceptor traps are shallow dishes that sit under each leg of your bed frame or couch. They exploit the fact that bed bugs can’t climb smooth surfaces. The outer wall is textured so bugs walk right in, but the inner moat is slick, trapping them. Placing interceptors on all four legs does two things: it stops floor-level bugs from climbing up to bite you, and it traps bugs already on the bed that drop down. You can buy commercial interceptors or make your own using two nested plastic containers with the inner walls coated in a thin layer of talcum powder to keep them slippery.
Check the traps every few days. They also double as a monitoring tool, giving you a clear picture of how many bugs are active and whether your other efforts are working.
Vacuuming Infested Areas
Vacuuming won’t end an infestation, but it physically removes live bugs, eggs, and shed skins from mattress seams, headboard crevices, carpet edges, and baseboards. Use a crevice attachment to get into tight spots. After vacuuming, immediately seal the vacuum bag or empty the canister into a plastic bag, tie it shut, and dispose of it outside your home. If you leave a bag full of live bed bugs sitting in a closet, they’ll crawl right back out.
Decluttering Hiding Spots
Bed bugs hide in clutter: stacked magazines, cardboard boxes under the bed, piles of clothes on the floor. Reducing clutter eliminates harborage sites and makes every other remedy more effective. You can actually reach the bugs with steam or a vacuum when they don’t have dozens of hiding places. Bag and seal anything you remove from the room before carrying it through the house, so you don’t spread bugs to new areas.
Sealing Cracks and Crevices
Caulking gaps along baseboards, around electrical outlet covers, and where furniture meets the wall removes hiding spots and travel routes. Bed bugs are flat enough to slip into cracks the width of a credit card. Silicone caulk or painter’s caulk works for most gaps. This won’t kill bugs, but it permanently eliminates harborage and makes your other treatments more effective by forcing bugs into the open.
Double-Bagging Infested Items
Sealing infested clothing, shoes, books, or soft goods in heavy-duty plastic bags isolates them and stops bugs from spreading while you work through your treatment plan. Use clear bags so you can see what’s inside without opening them. Items that can’t be washed or heated can be left sealed for months. Keep in mind that bed bugs survive a long time without food, so bagging alone isn’t a quick fix; it’s a containment strategy you pair with heat, freezing, or time.
Essential Oils as Spot Treatments
Certain essential oil compounds do kill bed bugs on direct contact, but the gap between their potency and conventional treatments is enormous. Purdue University researchers tested 15 essential oil compounds and found that carvacrol (from oregano and thyme), thymol (thyme), citronellic acid (lemongrass), and eugenol (clove) were the most toxic to bed bugs. As fumigants, thymol and carvacrol performed best.
Here’s the catch: the most effective essential oil compound required roughly 70,000 times more product to kill a bed bug by contact than a standard synthetic insecticide. As a vapor, the gap narrowed to about 400 times, which is still a massive difference. Essential oils may kill a few bugs you spray directly, but they won’t reach the ones hiding in wall voids or deep in furniture joints. Consider them a supplementary measure at best.
If you have cats or dogs, be cautious. Many essential oils, particularly tea tree oil and those high in phenols like thymol and eugenol, are toxic to pets when ingested or inhaled in concentrated amounts. Cats are especially sensitive because they lack certain liver enzymes needed to metabolize these compounds.
Diatomaceous Earth
Food-grade diatomaceous earth is a fine powder made from fossilized algae. It damages the waxy outer coating on bed bugs, causing them to dehydrate and die. Apply a thin, barely visible layer along baseboards, inside wall outlets (with the power off), under furniture legs, and around bed frames. A heavy pile won’t work; bugs will simply walk around it. The powder needs to be thin enough that bugs will walk through it without detecting a barrier. It works slowly, often taking several days to kill bugs that cross it, but it remains effective as long as it stays dry.
Baking Soda
Baking soda is commonly recommended online as a bed bug desiccant, similar to diatomaceous earth. The idea is that it absorbs moisture from the bug’s body. In practice, there’s no published research showing baking soda kills bed bugs at any meaningful rate. It’s far less abrasive than diatomaceous earth, so it doesn’t damage the outer shell effectively. If you want a powder-based approach, diatomaceous earth is the better choice.
Rubbing Alcohol as a Contact Spray
Rubbing alcohol dissolves a bed bug’s outer shell and then dries out its insides. It also destroys eggs the same way. But it only works on direct contact, and even then, the results are poor. Researchers at Rutgers University tested products containing 50% and 91% isopropyl alcohol, and neither killed more than half the bugs sprayed.
The bigger problem is safety. Isopropyl alcohol is extremely flammable. Spraying it on mattresses, upholstery, and carpets turns your bedroom into a fire hazard, and the lingering vapors are also flammable. In 2017, a woman in Cincinnati doused her furniture in alcohol to kill bed bugs; a nearby flame ignited the vapors, and the fire displaced 10 people. This remedy carries real risk for minimal effectiveness.
Isolating Your Bed
Pulling your bed away from the wall, removing any bed skirts or trailing blankets, and making sure nothing touches the floor between the bed frame and surrounding furniture creates a physical island. Combined with interceptor traps on each leg and a sealed mattress encasement, this setup means bed bugs on the floor can’t reach you and bugs trapped in the mattress can’t feed. It won’t eliminate the infestation, but it can stop you from getting bitten while your other treatments take effect. This is one of the most immediately useful steps you can take on day one.
When Home Remedies Aren’t Enough
These 15 approaches work best together, and they’re most effective for small, recently discovered infestations. If you’re finding bugs in multiple rooms, seeing them during the daytime (a sign of heavy population pressure), or still catching bugs in interceptor traps after weeks of consistent effort, the infestation has likely grown beyond what DIY methods can handle. Professional heat treatments raise entire rooms to 135°F, sustained long enough to kill bugs in every crack and crevice, something no combination of home steamers, dryers, and powders can replicate. A licensed pest control provider can also confirm that what you’re dealing with is actually bed bugs, since several other insects look similar and require different treatment.
