Treatment, without the hype
How to get rid of bed bugs. What actually works.
There is no one-and-done spray. The methods that clear an infestation are heat, careful use of the right products, physical barriers and monitoring — combined, and repeated, because eggs keep hatching and many bed bug populations now shrug off the sprays sold for them. Here is every real method, what it does, whether you can do it yourself, and the ones that only make things worse. All of it is drawn from the EPA and university entomology programs.
What actually works
No single row below is a cure on its own. Beating bed bugs means stacking several of these and following up — the approach the EPA calls integrated pest management.
| Method | How it kills | You or a pro? | The catch |
|---|---|---|---|
| Professional heat | Whole room raised to 135–145°F — kills every stage, including eggs, in one visit. | Pro | Equipment you can’t rent safely; leaves no residual, so bugs can return without follow-up. |
| Steam | Direct surface heat (must reach at least 130°F) cooks bugs and eggs in seams and crevices. | You | Surface-only and slow; use low airflow or you scatter them. EPA |
| Clothes dryer | 30 minutes on high heat kills all stages in bedding and clothes. | You | Only for launderable items; the heat, not the wash, is what kills. EPA |
| Cold / freezing | Sealed items held at 0°F for about four days. | You | Many home freezers aren’t that cold — use a thermometer, and it’s slow. EPA |
| Mattress encasements | Seal the mattress and box spring so trapped bugs starve and new ones can’t hide. | You | Leave on for at least a year; it’s a barrier and monitor, not a stand-alone kill. |
| Interceptor cups | Trap bugs climbing the bed legs and show whether any are still active. | You | Monitoring and reduction, not eradication on their own. EPA |
| Vacuuming | Physically removes live bugs and shed skins from seams and cracks. | You | Doesn’t kill eggs; seal and bin the bag immediately. |
| EPA-registered insecticides | Over 300 products are registered for bed bugs; used correctly they kill on contact and can leave residual. | You or pro | Resistance is now common — must be labeled for bed bugs and indoor use, and never the only step. EPA · UC IPM |
Temperatures and times: U.S. EPA and university extension research. Research finds bugs and eggs die within about 90 minutes at 118°F, and effectively at once by 122°F.
What doesn’t work — or makes it worse
Ineffective & spreads it
Bug bombs / foggers
The mist never reaches bugs hidden in cracks, and it drives survivors into other rooms and units. The EPA “strongly recommends against” them. EPA
Fire hazard
Rubbing alcohol, kerosene, gasoline
They “can easily ignite,” and homes have burned down this way. Never a treatment. EPA
Dangerous & useless
DIY space / propane heaters
Trying to heat a room yourself “does not work and is dangerous.” Whole-room heat needs professional gear. EPA
No evidence
Vinegar, essential oils, baking soda
None of the popular home “cures” clear an infestation. Time spent on them is time the bugs spend breeding.
Why one treatment is never enough
- Eggs survive what adults don’t. They keep hatching for days after a treatment, so a single pass leaves the next generation behind. Plan on follow-up visits or repeat rounds.
- The common sprays are losing their punch. Many bed bug populations have developed resistance to synthetic pyrethroids — a big reason heat and combined methods have taken over. A product that worked a decade ago may do little now. UC IPM · extension research
- Confirm it’s actually over. A quiet week isn’t proof. Keep interceptors down and re-inspect — see did it work?
Do it yourself, or hire a pro?
DIY can work when
It’s light and early
You caught it fast, it’s one room, and you can commit to weeks of encasements, interceptors, laundering, vacuuming and careful, labeled product use with follow-up. Check any product on our ingredient checker and the details on heat & cold.
Call a pro when
It’s established or shared
Heavy or spreading, or you share walls (condo, apartment, duplex) where a single unit alone re-infests. Professional heat and canine inspection are tools most people can’t match — verify the license for bed bug work first. If you rent, your state’s page shows who pays.
