Step-by-Step Instructions
Confirm the infestation with a flashlight inspection before you act
The first and most important step is to confirm that you actually have bed bugs and not a similar looking insect such as carpet beetles, bat bugs, or spider beetles. A misidentification leads to a wrong treatment and weeks of wasted effort. Strip the bed completely and inspect the seams, tags, and piping of the mattress and box spring with a bright flashlight. Adult bed bugs are reddish brown, flat, oval, and approximately the size of an apple seed at five to seven millimeters. Look for live bugs, translucent shed skins, small dark spots that are dried fecal matter, and tiny pearl colored eggs in seams. Check the headboard, the bed frame joints, the baseboards behind the bed, and the seams of any upholstered furniture within ten feet of the bed. Take clear photos of any insect you find and compare against authoritative reference images before starting treatment.
Strip and bag every fabric item in the affected room
Pull every sheet, pillowcase, blanket, mattress pad, curtain, and washable item from the affected room and place them directly into heavy duty plastic trash bags. Tie each bag tightly closed before carrying it through the rest of the house. Carrying loose contaminated fabric through other rooms is the single most common way that bed bugs spread from one room to the entire house. Do not pile contaminated items on the floor of any other room. Carry the sealed bags directly to the laundry room or to the car for transport to a laundromat. Mark each bag with painter's tape so you can tell which bags contain potentially contaminated items versus which are already treated.
Wash and dry every fabric on the highest heat setting both items can tolerate
Bed bugs and their eggs die at sustained temperatures above one hundred eighteen degrees Fahrenheit. The dryer is more effective than the washer for killing bed bugs because it consistently reaches and maintains higher temperatures. Wash items in hot water if the care label allows, and then dry them on the highest heat setting for a minimum of thirty minutes after the load is dry to the touch. The thirty minute heat dwell after dryness is what kills the eggs that survive the wash cycle. For items that cannot tolerate hot water such as wool sweaters or delicate fabrics, skip the wash and run them in the dryer alone on the highest tolerated heat setting for forty five minutes. For broader laundry routines that pair with this treatment, see our how to make laundry smell good after washing guide.
Vacuum every crevice in the affected room with a crevice tool attachment
Use the crevice tool attachment of your vacuum to slowly trace every seam, edge, joint, and crack in the mattress, box spring, bed frame, headboard, baseboards, electrical outlet covers, and any furniture in the room. Move the vacuum slowly along each line because suction is what physically removes the bugs and eggs. Pay extra attention to the seams of the mattress and box spring, the corners of the bed frame, and the gap where the carpet meets the wall. After vacuuming, immediately remove the vacuum bag or empty the canister into a sealed plastic bag and take the bag directly to the outdoor trash bin. Bed bugs survive inside vacuum bags and can climb back out through the hose if the bag is not removed promptly.
Steam clean the mattress, box spring, and surrounding areas at high temperature
A handheld steam cleaner that produces steam at two hundred degrees Fahrenheit or higher is the most effective non chemical treatment for killing bed bugs at every life stage including eggs. Move the steam wand slowly along every seam of the mattress, box spring, bed frame, and any upholstered furniture, holding the nozzle approximately one inch from the surface. The slow movement is what allows the heat to penetrate into the seams where bugs and eggs hide. Steam clean the carpet around the bed in a three foot radius, the baseboards, and any cracks in the floor or wall near the bed. The combination of heat and moisture penetrates further into hiding spots than any vacuum or chemical treatment alone.
Encase the mattress and box spring in zippered bed bug proof covers
After the steam treatment, install a zippered bed bug proof encasement on both the mattress and the box spring. Look specifically for encasements that are labeled as bed bug certified, which means the zipper is fine enough to prevent bugs and eggs from passing through. Standard mattress protectors are not bed bug proof and do not solve the problem. The encasement traps any surviving bugs inside where they cannot bite you, and they will eventually die from lack of feeding within twelve to eighteen months. Leave the encasements on for at least eighteen months even if you stop seeing signs of bugs. Removing the encasement early releases any surviving bugs back into the room and restarts the infestation cycle.
Apply food grade diatomaceous earth to cracks and crevices around the bed
Food grade diatomaceous earth is a fine powder made of fossilized algae that physically damages the exoskeleton of bed bugs and causes them to dehydrate and die. Use a small puffer applicator to apply a very thin dust layer along baseboards, in cracks, around electrical outlets, under the bed legs, and in any crevice where bugs might hide. The thin layer is critical because bed bugs avoid thick visible piles of powder. The goal is a dusting so light that it is barely visible. Leave the diatomaceous earth in place for at least two weeks before vacuuming it up. Reapply if any of the treated areas get disturbed or wet. Use only food grade diatomaceous earth, never the pool grade version which is processed differently and is hazardous to breathe at the levels used for pest control.
Move the bed away from walls and use bed bug interceptor cups under the legs
Pull the bed approximately six inches away from any wall and remove any bed skirts that touch the floor. Bed bugs cannot fly or jump, so they reach the bed by climbing up the legs from the floor or by crossing from a touching wall. Place a bed bug interceptor cup under each leg of the bed. The interceptors are smooth walled plastic cups with a moat in the middle that bed bugs can climb into but not climb out of. The interceptors serve two purposes: they prevent bugs from reaching the bed where you sleep, and they catch and let you count bugs as a measurement of treatment progress. A weekly count of trapped bugs that drops to zero over four to six weeks is the strongest sign that the infestation is under control.
Treat or discard infested furniture using the same heat protocol
Any upholstered furniture in the affected room should receive the same vacuum and steam treatment as the bed. For severely infested couches, chairs, or other furniture that cannot be effectively treated, the best option is often to discard the item rather than risk a re infestation. If you discard infested furniture, label it clearly with paint or a sign as bed bug infested before placing it on the curb so other people do not pick it up and spread the infestation to a new home. For items that have sentimental value or are too expensive to replace, professional heat chamber treatment is available in most metropolitan areas and exposes the entire item to one hundred forty degrees Fahrenheit for several hours, which kills every life stage of the infestation in a single session.
Repeat the inspection vacuum and steam cycle every seven days for six weeks
Bed bug eggs hatch on a six to ten day cycle, and a single treatment session does not eliminate eggs that hatch after the treatment. Repeat the full inspection, vacuum, and steam treatment cycle every seven days for at least six weeks regardless of whether you continue to see live bugs. The repeat treatments catch each new generation as the eggs hatch and prevent the infestation from rebuilding from a few survivors. Track the count of bugs found in the interceptor cups under each bed leg every week. The count should decline week over week and should reach zero by approximately week four to six. If the count is not declining by week three, consider professional pest control intervention because the infestation may be more widespread than the visible signs suggested.
When to call a professional pest control company
Professional intervention is justified in three specific scenarios. First, if you find live bed bugs in more than one room of the home, the infestation has spread beyond the contained level where DIY treatment is reliably effective and a professional whole home treatment is the faster path to elimination. Second, if six weeks of consistent DIY treatment has not reduced the interceptor cup count to zero, the treatment is not addressing all of the hiding spots and a professional inspection can identify the missed areas. Third, if any household member has a severe allergic reaction to the bites or has a compromised immune system, the time pressure justifies the cost of professional treatment. Reputable pest control companies use a combination of heat treatment, residual chemical applications, and targeted insecticide application that achieves elimination significantly faster than DIY methods. Expect costs of approximately five hundred to fifteen hundred dollars for a single bedroom treatment depending on region and severity. For complementary kitchen and pantry pest prevention while the bedroom is being treated, see our ten best ways to combat cockroaches.
Mistakes that turn a contained infestation into a whole home problem
Mistake one: spraying over the counter pesticides on the mattress without doing the mechanical removal first. Bed bugs have developed resistance to most commonly available pyrethroid pesticides, and spraying without vacuuming and steaming first scatters the bugs into adjacent rooms where they hide and survive. Always do the physical removal before any chemical application. Mistake two: throwing a mattress out without sealing it in plastic and labeling it as bed bug infested. An unmarked discarded mattress is often picked up by another household and spreads the infestation to a new location, and bugs can fall off the mattress during the carry to the curb and infest other rooms in your own home. Mistake three: continuing to sleep in a different room of the same home during treatment. Bed bugs follow the carbon dioxide and body heat of a sleeping person, and moving to a guest room or couch invites the infestation to spread to the new sleeping location within one to two weeks. Stay in the affected room with interceptor cups installed under the bed legs so the infestation stays contained while you treat. Mistake four: doing a single intensive treatment and assuming the problem is solved. Bed bug eggs hatch on a six to ten day cycle and a single treatment cannot kill eggs that hatch after the treatment. The full six week schedule of weekly repeat treatments is what eliminates the infestation completely. Mistake five: using essential oils such as tea tree oil or lavender oil as the primary treatment based on social media advice. The natural oil approach has not been validated against bed bugs at the concentrations safe for indoor use, and time spent on ineffective treatments allows the infestation to grow significantly. Use the proven heat, vacuum, steam, encasement, and diatomaceous earth protocol instead.
Pro Tips
- ✓Wash and dry every fabric item from the affected room on the highest heat setting both items can tolerate. The dryer is more effective than the washer because it consistently reaches and maintains the temperatures above one hundred eighteen degrees Fahrenheit that kill bed bugs and their eggs. Run the dryer for a minimum of thirty minutes after the load is dry to the touch.
- ✓Install zippered bed bug certified encasements on both the mattress and the box spring after the initial heat and steam treatment, and leave the encasements in place for at least eighteen months. The encasement traps any surviving bugs inside where they cannot feed and they eventually die. Removing the encasement early releases survivors back into the room and restarts the infestation cycle.
- ✓Repeat the full inspection, vacuum, and steam treatment cycle every seven days for at least six weeks regardless of whether you still see live bugs. Bed bug eggs hatch on a six to ten day cycle and the repeat treatments catch each new generation as it emerges. Track the weekly count of bugs trapped in interceptor cups under the bed legs as a measurable indicator of treatment progress.

Safety Notes
- ⚠Use only food grade diatomaceous earth, never the pool grade version. Pool grade diatomaceous earth is processed differently and is hazardous to breathe at the levels used for pest control. Apply food grade diatomaceous earth in a very thin barely visible layer to avoid any inhalation risk during application.
- ⚠Do not apply over the counter pesticides directly to mattress surfaces, pillows, or any soft surface that contacts skin during sleep. Most pesticides are not formulated for direct skin contact and can cause irritation, allergic reaction, or chemical absorption through the skin. Use only physical and heat based treatments on items that contact skin.
- ⚠If a household member has a severe allergic reaction to the bites or develops widespread skin reactions, seek medical attention promptly and consider professional pest control intervention. The time pressure of the medical risk justifies the cost of professional treatment, which achieves elimination significantly faster than DIY methods.
Frequently Asked Questions
How do you get rid of bed bugs permanently?
Bed bug elimination requires a combination of mechanical removal, heat treatment, encasement, and repeat treatment over six weeks. First, confirm the infestation with a flashlight inspection of mattress seams, headboards, and baseboards. Strip and bag every fabric item from the affected room and wash and dry on the highest heat setting for at least thirty minutes after the load is dry. Vacuum every crevice with a crevice tool and immediately empty the canister into a sealed bag in the outdoor trash. Steam clean the mattress, box spring, and surrounding three foot radius at two hundred degrees Fahrenheit or higher. Install zippered bed bug certified encasements on the mattress and box spring and leave them in place for at least eighteen months. Apply a thin layer of food grade diatomaceous earth along baseboards and cracks. Move the bed away from walls and install bed bug interceptor cups under the legs. Repeat the inspection, vacuum, and steam cycle every seven days for at least six weeks because eggs hatch on a six to ten day cycle and the repeat treatments catch each new generation.
What temperature kills bed bugs?
Bed bugs and their eggs die at sustained temperatures above one hundred eighteen degrees Fahrenheit. The dryer is more effective than the washer for killing bed bugs because it consistently reaches and maintains higher temperatures, and a dryer run on the highest heat setting for at least thirty minutes after the load is dry to the touch reliably kills both adult bugs and eggs in fabric items. For surfaces that cannot be put in a dryer, a handheld steam cleaner that produces steam at two hundred degrees Fahrenheit or higher is the most effective non chemical treatment because the heat and moisture penetrate into the seams where bugs and eggs hide. Professional heat chamber treatment exposes entire pieces of furniture to one hundred forty degrees Fahrenheit for several hours, which kills every life stage in a single session.
Can I get rid of bed bugs without a pest control company?
Yes, contained bed bug infestations limited to a single bedroom can usually be eliminated through DIY treatment using the heat, vacuum, steam, encasement, and diatomaceous earth protocol over six weeks of weekly repeat treatments. Track the count of bugs trapped in interceptor cups under each bed leg every week as a measurable indicator of progress. The count should decline week over week and reach zero by approximately week four to six. Professional intervention is justified in three scenarios: if live bugs are found in more than one room, if six weeks of consistent DIY treatment has not reduced the count to zero, or if a household member has a severe allergic reaction or compromised immune system that makes the time pressure of professional treatment worth the approximate five hundred to fifteen hundred dollar cost for a single bedroom treatment.
