How to Get Rid of Bed Bugs: Complete Treatment Guide (2026)

Last updated: March 3, 2026

Getting rid of bed bugs requires a systematic approach. These pests hide in mattress seams, furniture joints, baseboards, and electrical outlets, making them one of the hardest household pests to eliminate. While mild cases can sometimes be managed with DIY methods, most established infestations require professional treatment for complete elimination.

This guide walks you through how to confirm you have bed bugs, which DIY methods actually work (and which do not), when to call a professional, and what to expect from professional treatment. For pricing details, see our bed bug treatment cost guide.

Step 1: Confirm You Have Bed Bugs

Before spending money on treatment, confirm that bed bugs are the actual problem. Misidentification wastes time and money on the wrong approach.

Signs of bed bugs

• Bites in clusters or lines. Bed bug bites typically appear in groups of three to five on exposed skin, often in a line. They are flat or slightly raised red bumps that may take hours or days to appear.
• Dark spots on mattress seams. Bed bug excrement leaves tiny dark brown or black spots along mattress seams, box spring edges, and headboard joints.
• Bloodstains on sheets. Small rust-colored spots on your pillowcase or sheets from bed bugs crushed after feeding.
• Shed skins. Translucent, light-brown shells near hiding spots indicate bed bugs are molting and growing.
• Live bugs. Adult bed bugs are reddish-brown, flat, oval-shaped, and about the size of an apple seed. Check mattress seams, bed frame joints, and behind headboards.

Where to look

Start with the mattress. Pull back the sheets and inspect every seam, fold, and tag on the mattress and box spring. Then check the bed frame joints, headboard (especially the back side against the wall), nightstand drawers, baseboards near the bed, and electrical outlet covers. Use a flashlight and a credit card to probe crevices.

Step 2: DIY Methods That Work

These DIY methods can reduce bed bug populations and are worth trying for mild infestations caught early (a few bugs in one room, no signs elsewhere). Even if you plan to hire a professional, these steps help prepare and speed up the process.

Laundering

Wash all bedding, clothing from affected rooms, curtains, and fabric items in hot water (at least 120°F) and dry on the highest heat setting for at least 30 minutes. The heat from the dryer is what kills bed bugs, not the washing. Items that cannot be washed can be placed in a dryer on high heat for 30 minutes. This kills bugs and eggs on contact.

Vacuuming

Vacuum every surface in the affected room: mattress (all seams), box spring, bed frame, baseboards, carpet edges, upholstered furniture, and any cracks or crevices. Use the crevice tool attachment. After vacuuming, immediately seal the vacuum bag in a plastic bag and dispose of it outside. If you have a bagless vacuum, empty the canister into a sealed bag and clean the filter. Vacuum daily for at least two weeks.

Mattress and box spring encasements

Encase your mattress and box spring in bed bug-proof encasements ($20 to $50 each). These zippered covers trap any remaining bugs inside where they cannot feed and will eventually die. They also create a smooth surface that makes it easier to spot new bugs. Leave encasements on for at least 12 months, as bed bugs can survive up to a year without feeding.

Interceptor traps

Place bed bug interceptor cups ($8 to $15 for a set of four) under each bed leg. These small plastic traps catch bugs climbing up or down the bed legs, both reducing the population and helping you monitor activity. Check traps weekly. Finding bugs in the outer well means they are coming from the room; bugs in the inner well were on the bed.

Diatomaceous earth (food-grade)

Apply a thin layer of food-grade diatomaceous earth along baseboards, behind outlets, in cracks, and under furniture. This powder damages the waxy coating on bed bug exoskeletons, causing them to dehydrate over days. It is non-toxic to humans and pets but works slowly (kills bugs over 7 to 14 days of contact). Apply lightly; thick piles are less effective because bugs will walk around them.

Steam cleaning

A steam cleaner producing steam at 160°F or higher kills bed bugs on contact. Slowly pass the steamer over mattress seams, bed frames, baseboards, and upholstered furniture. Move at about 1 inch per second to ensure the heat penetrates. Steam is effective but only kills bugs where it reaches directly; it does not penetrate deep into wall voids or furniture interiors.

Methods That Do NOT Work

These popular products and approaches are either ineffective or can make bed bug problems worse. Do not waste money on them.

Bug bombs and foggers

Total-release foggers ("bug bombs") are one of the least effective methods against bed bugs. Multiple studies have confirmed that foggers fail to penetrate the cracks and crevices where bed bugs hide. Worse, the chemical dispersal can scatter bed bugs to adjacent rooms, spreading the infestation. The EPA and pest control professionals advise against using foggers for bed bugs.

Ultrasonic pest repellers

Plug-in ultrasonic devices that claim to repel pests with sound waves have no scientific evidence supporting their effectiveness against bed bugs. The FTC has taken action against companies making false claims about these devices.

Essential oils and natural sprays

While some essential oils (tea tree, lavender) may repel bed bugs temporarily, they do not kill them reliably and have no effect on eggs. They can provide a false sense of security while the infestation grows.

Rubbing alcohol

Rubbing alcohol kills bed bugs on direct contact but evaporates within minutes, leaving no residual protection. It cannot reach bugs in hiding spots. Using large amounts of rubbing alcohol also creates a serious fire hazard. Several house fires have been attributed to alcohol-based bed bug treatments.

Step 3: When to Call a Professional

Call a professional exterminator if any of the following apply:

• Bugs in multiple rooms. Once bed bugs spread beyond one room, DIY methods are unlikely to reach all hiding spots.
• Infestation has been present for more than two weeks. An established population with breeding adults requires stronger treatment.
• DIY methods have not worked after two weeks. If you are still finding live bugs or getting new bites after thorough DIY treatment, professional help is needed.
• You live in a multi-unit building. Bed bugs can travel between apartments through wall voids, plumbing, and electrical conduits. Treating one unit without addressing the source is futile.
• Heavy infestation. If you see bugs during the day, find them in multiple pieces of furniture, or see large clusters of dark spots, the population is large enough to require professional intervention.

Step 4: Professional Treatment Options

Professional exterminators use methods that are significantly more effective than anything available to consumers. Here are the main options.

Heat treatment is the fastest and most effective single-visit option. Industrial heaters raise room temperatures to 130-140°F for several hours, killing bed bugs and eggs in all hiding spots. The main drawback is cost and the need to remove heat-sensitive items.

Chemical treatment is more affordable and uses professional-grade residual insecticides that continue killing bugs for weeks. However, most chemicals do not kill eggs, so two to three visits spaced two weeks apart are needed to catch newly hatched bugs.

Step 5: Preparing for Professional Treatment

Proper preparation is critical for treatment success. Most companies provide a preparation checklist. Incomplete preparation is one of the top reasons treatments fail.

1. Launder everything. Wash and dry all clothing, bedding, curtains, and fabric items on high heat. Store clean items in sealed plastic bags until after treatment.
2. Declutter. Remove items from under beds, clear closet floors, and reduce hiding spots. Discard heavily infested items (seal them in plastic and label "bed bugs" before placing in the trash).
3. Vacuum thoroughly. Vacuum all floors, carpets, mattresses, and furniture. Dispose of the vacuum bag outside.
4. Pull furniture away from walls. Move beds, dressers, and couches 6 to 12 inches from walls so the technician can access all edges.
5. Empty dressers and nightstands. Remove all items from drawers and shelves near the bed.
6. Do not move items to other rooms. This spreads bed bugs. Keep all items in the affected room.

Step 6: Preventing Reinfestation

After treatment, these steps significantly reduce the risk of bed bugs returning.

• Keep mattress encasements on for at least 12 months. Do not remove them even if treatment was successful.
• Continue using interceptor traps under bed legs. Check weekly for at least three months after treatment.
• Inspect regularly. Check mattress seams and bed frame joints every two weeks for the first three months, then monthly.
• Be cautious with secondhand furniture. Inspect any used furniture thoroughly before bringing it into your home. Avoid picking up furniture left on the curb.
• Use luggage precautions when traveling. Keep suitcases on luggage racks (not the floor or bed), inspect hotel mattresses before unpacking, and wash all travel clothing on high heat immediately after returning home.
• Address the source. If you live in a multi-unit building, work with your landlord or property manager to inspect and treat adjacent units.
