Key Takeaways
- You can get rid of bed bugs yourself, but not with one spray. It takes a methodical plan run over several weeks — and diligence matters more than any single product.
- Heat is your most powerful weapon. Bed bugs die at 118–122°F, so hot-dryer laundering and steaming do the heavy lifting, with no resistance issues.
- Sprays alone usually fail. Bed bugs are widely resistant to common pesticides, and in studies thorough non-chemical methods actually beat insecticide-only treatment.
- Be patient and persistent. Bed bugs can live months without feeding, so plan on monitoring for weeks and re-treating. Call a professional if it isn’t shrinking.
Getting rid of bed bugs is absolutely doable at home, but it’s a process, not a product. The infestations that come back are almost always the ones where someone sprayed once and hoped. The ones that end for good follow a sequence: confirm, contain, heat, encase, treat the hiding spots, and monitor. Here’s exactly how to do that, with links to the detailed how-to for each step.
Can you really get rid of bed bugs yourself?
Yes — and the data is encouraging for the DIY approach. In a field study of infested apartments, thorough non-chemical methods alone eliminated bed bugs in about 67% of units, compared with roughly 33% for insecticide-only treatment, with the best outcomes coming from a diligent combination (EPA: IPM for bed bugs). The lesson: heat, encasement, vacuuming, and monitoring — done carefully — outperform reaching for a spray. This combined approach is called Integrated Pest Management (IPM), and it’s what the steps below follow.
Step 1: Confirm it’s actually bed bugs
Before you treat, be sure. Look for live bugs (apple-seed-sized, reddish-brown), rusty spots on sheets, shed skins, and bites in rows. Our guide on how to check for bed bugs walks through where to inspect, and what bed bug bites look like helps you rule out other causes. Treating for the wrong pest wastes weeks.
Step 2: Contain the spread
Don’t start hauling infested items through the house — that spreads them. Bag up bedding, clothing, and soft items in sealed plastic bags right in the room, and keep them sealed until you treat them. Don’t move furniture to another room. Reducing clutter at the same time removes the hiding spots bed bugs depend on.
Step 3: Heat-treat and launder everything washable
This is the highest-impact step. The dryer’s heat — not the wash — kills bed bugs and eggs, so run washable items on high for at least 30 minutes (how to use your washer and dryer). For things you can’t wash:
- Delicate fabrics and wool: freeze at 0°F for at least four days.
- Leather goods: inspect and steam the seams rather than using heat that cracks them.
Step 4: Encase the mattress and box spring
Seal the mattress and box spring in bed bug-proof, zippered encasements. This traps any bugs inside (they can’t feed and die off) and stops new ones from hiding in your mattress. Leave the encasements on for at least a year, since bed bugs can survive that long without a meal (EPA). See our picks for bed bug mattress covers.
Step 5: Treat the cracks and crevices where they hide
Bed bugs spend most of their time hidden in seams, frames, and baseboards, so this is where treatment counts:
- Steam kills on contact in those gaps — see the best bed bug steamers and how to use them.
- Desiccant dust (like diatomaceous earth) kills bugs that walk through it over several days; apply a thin layer in cracks — see our diatomaceous earth guide.
- Sprays can help as part of the mix, but choose carefully: bed bugs are widely resistant to common pyrethroids, and no spray works alone (best bed bug sprays).
Step 6: Monitor with interceptors
Place interceptor cups under each bed leg to catch bugs traveling to and from the bed. They tell you whether the population is shrinking and keep the bed isolated. Check them weekly.
Step 7: Repeat — and know when to call a pro
Bed bugs are persistent. Re-treat (re-launder, re-steam, re-check) every week or two, and keep monitoring for weeks after you stop seeing them. If the problem isn’t clearly shrinking after a few rounds, bring in a licensed professional. Professional heat treatments raise a whole room to 130–140°F, reaching voids no DIY method can.
What doesn’t work (skip these)
Save your money and your safety:
- Rubbing alcohol — kills only about half even sprayed directly, and it’s a fire hazard.
- Bleach — harsh, damaging, and can’t reach the hiding spots.
- UV lights — a detection aid at best, not a treatment.
- Foggers / “bug bombs” — they don’t penetrate the cracks where bed bugs hide and can scatter them deeper, making things worse.
How long does it take to get rid of bed bugs?
Plan on several weeks. A diligent DIY effort usually takes about 3–6 weeks of repeated treatment and monitoring, because you have to outlast the eggs hatching and any bugs you missed. Stopping too early is the most common reason infestations rebound.
Frequently asked questions
Can you get rid of bed bugs permanently on your own?
Yes, many people do — with a consistent IPM plan (heat, encasements, crevice treatment, and monitoring) carried out over several weeks. “Permanent” depends on follow-through and on preventing re-introduction from travel or used items.
What kills bed bugs instantly?
Direct heat of about 122°F kills them almost immediately, which is why a hot dryer, steam, and professional heat treatments are the most reliable tools.
Do I need a professional?
Not always. Small, early infestations are very treatable at home. Call a pro if it’s widespread, keeps coming back after diligent effort, or you can’t use heat/laundering effectively (for example, in a heavily cluttered or multi-unit building).
Why didn’t the spray I bought work?
Most over-the-counter sprays are pyrethroids, and bed bugs are now widely resistant to them. Sprays also don’t reach eggs or deep harborage. They’re a supporting tool within a plan, never the whole plan.
