Quick answer
Heat is what kills bed bug eggs most reliably. A clothes dryer on its hottest setting for 30 minutes, steam of at least 130°F moved slowly over seams, and professional whole-room heat all kill eggs. Freezing at 0°F also works, but it takes about 3 to 4 days, not hours. The only thing close to “instant” is direct steam on an egg you can reach. Most sprays, rubbing alcohol and diatomaceous earth do not kill eggs well, so plan for a follow-up after any treatment, because eggs that survive hatch about 1 to 2 weeks later.
Eggs are the reason so many bed bug problems come back. A spray kills the adults, the room looks clear for a week, then a new wave of nymphs shows up from eggs that survived.
This guide covers what kills bed bug eggs, what does not, and how long each method takes. Every temperature and time comes from the EPA, university entomologists or peer-reviewed research.
Key takeaways
- Heat kills bed bug eggs. Eggs are tougher than adults, so they need higher heat or more time.
- Dry bedding and clothes on high for 30 minutes. Steam must reach at least 130°F at the surface.
- Freezing works only at 0°F or colder, in a sealed bag, for at least 3 to 4 days.
- Vacuuming removes few eggs because they are glued down. Encasements trap eggs but do not kill them on the spot.
- Rubbing alcohol does not kill eggs and is a fire hazard. Diatomaceous earth is slow and does not kill eggs directly.
- Plan a follow-up 1 to 2 weeks later, because missed eggs hatch.
What Kills Bed Bug Eggs?
The short answer is heat, and enough of it. The University of California IPM Program (UC IPM) says steam can kill all bed bug life stages, and professional heat of 140°F for 2 hours or 130°F for 3 hours kills most bugs and eggs. Texas A&M AgriLife Extension says 30 minutes in a dryer on high kills all stages.
Cold works too, but only when it is very cold for a long time. Most other methods work slowly, only on part of the problem, or not at all on eggs. The checker below rates each one.
Bed Bug Egg Method Checker
Tap a method to see how well it works on eggs. Ratings summarize the sources listed at the end.
Egg rating: 5 of 5
What it takes: the hottest setting for 30 minutes, which Texas A&M says kills all stages. UC IPM says at least 10 to 15 minutes is needed, so 30 adds a margin.
The catch: only for items that fit and can take the heat.
Egg rating: 4 of 5
What it takes: at least 130°F at the surface with no forceful airflow, per the EPA. The University of Kentucky says steamers used correctly kill eggs on contact.
The catch: it misses eggs deep in walls, outlets and box spring frames.
Egg rating: 5 of 5
What it takes: pro equipment holding the room at 140°F for 2 hours or 130°F for 3 hours, per UC IPM.
The catch: trained technicians only. Space heaters have burned down homes, the EPA warns.
Egg rating: 4 of 5, small items only
What it takes: a sealed bag at 0°F, checked with a thermometer. The EPA says 3 days, and a 2013 study recommends at least 3.5 days.
The catch: many home freezers are not that cold, and eggs are the most cold-hardy stage.
Egg rating: 2 of 5
What it takes: a crevice tool, repeated often. UC IPM says one pass rarely gets all bugs and eggs.
The catch: eggs are glued down, and Texas A&M says vacuuming is not very good at removing them.
Egg rating: 3 of 5, over time
What it takes: bed bug encasements left on for well over a year. Eggs inside still hatch, but UC IPM says trapped bugs eventually die.
The catch: it does nothing for the frame or the rest of the room.
Egg rating: 1 of 5
What it does: Texas A&M says alcohol-based sprays do not kill eggs. In Rutgers tests, about half of sprayed adults were alive 4 days later.
The danger: the EPA says it has caused numerous house fires.
Egg rating: 1 of 5
What it does: dusts dry out bugs that crawl through them, per UC IPM. Eggs do not crawl, so at best DE catches some nymphs after hatching. The EPA says desiccants may take months.
The catch: use only registered, labeled DE. Pool or food grade DE can harm your lungs.
Egg rating: 3 of 5
What it takes: an EPA-registered product labeled for bed bug eggs (ovicidal), used exactly per label. A 2025 Virginia Tech study found egg results vary a lot by product, though some residues killed the nymphs that hatched.
The catch: some bed bugs resist pyrethroids, UC IPM notes, and sprays only hit eggs they touch.
Egg rating: 4 of 5
What it takes: a licensed fumigator seals the building and uses sulfuryl fluoride gas, which UC IPM says is available for bed bugs in California. Everyone must leave.
The catch: no residue, so it does not stop new bugs. Highly specialized and regulated.
Ratings are a plain-language summary for eggs only, not a product endorsement. Always follow the product label.
Why Bed Bug Eggs Are So Hard to Kill
Four things protect bed bug eggs:
- They are glued down. The University of Kentucky says eggs are sticky when laid and are difficult to dislodge.
- They are hidden. They sit in seams, screw holes and cracks where sprays and steam may not reach.
- The shell is a barrier. Many products that kill adults on contact have little effect on eggs, and studies show egg results vary by product.
- They are tougher than adults. University of Minnesota research found eggs need more heat than adults to die, and the egg is the most cold-hardy stage too.
That is why the EPA says you may have to repeat steps to kill all the eggs. Not sure the specks are eggs? See what bed bug eggs look like.
What Temperature Kills Bed Bug Eggs?
Researchers Stephen Kells and Michael Goblirsch at the University of Minnesota tested bed bugs under conditions like real heat treatments. Eggs needed about 131°F (54.8°C) to reach a 99% kill, versus about 119°F (48.3°C) for adults. At 118°F (48°C), eggs needed about 71.5 minutes, and at 113°F (45°C) they survived 7 hours.
So the honest answer is: eggs die at about 118°F if the heat holds for over an hour, and almost right away at about 131°F. That is why a warm attic or a space heater is not enough, and why our technicians hold rooms at 130°F to 140°F for hours.
What about a hot car? The EPA says black plastic bags in a hot, closed car in the sun can work, but success depends on your climate. The center of a packed bag may never get hot enough, so the dryer is safer.
What Kills Bed Bug Eggs Instantly?
Very little is truly instant. The closest options are:
- Direct steam at 130°F or more at the surface, on eggs it actually reaches. The University of Kentucky says steamers used correctly kill eggs on contact.
- Crushing eggs you can see, such as by scraping a seam with a stiff card or pressing with tape. It works on that egg, but you will miss most of the ones you cannot see.
“Kills on contact” sprays usually mean adult bugs, and Texas A&M is clear that alcohol-based sprays do not kill eggs. For a whole room, nothing is instant. A same-day professional heat treatment is the fastest real option.
How to Kill Bed Bug Eggs Naturally
The good news: the methods that work best on eggs are also chemical free. Heat, steam, cold, vacuuming and encasements use no pesticide at all.
Natural methods that work
- Dryer on high for 30 minutes
- Steam, at least 130°F, slow passes
- Sealed bags in a 0°F freezer for 3 to 4 days
- Scraping and vacuuming seams, repeated often
- Encasements to trap whatever hatches
“Natural” ideas that fail on eggs
- Rubbing alcohol, which does not kill eggs and burns
- Pool or food grade diatomaceous earth
- Vacuuming alone, which leaves glued eggs behind
- Mothballs, which eggs survived in Rutgers tests
- Essential oil sprays as your only treatment
What about essential oils? Results are mixed. Texas A&M notes 2 plant oil products did surprisingly well against bed bugs and their eggs in testing. But in other Rutgers tests, bugs sprayed with an essential oil product survived once they were allowed to feed, as they would in a real home. Do not rely on them alone.
How to Kill Bed Bug Eggs Before They Hatch: Step by Step
This plan focuses on eggs. For the full room plan, including adults and monitoring, see our guide on how to get rid of bed bugs.
- Find the egg spots first. Shine a flashlight at a low angle on mattress seams, box spring wood and bed frame joints. Look near bed bug droppings.
- Bag fabrics in the room. Seal bedding, clothes and soft items in plastic bags before you carry them out, so eggs and nymphs do not drop along the way.
- Dry on high for 30 minutes. You can skip washing for items that are already clean and dry. UC IPM advises checking first whether heat will damage the fabric.
- Freeze what cannot be heated. Seal small items in a bag in a 0°F freezer for at least 3.5 days.
- Scrape, then vacuum. Run a stiff card or brush along seams to loosen eggs, then vacuum with a crevice tool. Seal the vacuum contents in a bag and put it in an outdoor trash bin.
- Steam the seams slowly. At least 130°F at the surface, with a diffuser, over seams, tufts and frame joints.
- Encase the mattress and box spring. Anything you missed inside will hatch into a trap. Leave the covers on for well over a year.
- Repeat in 1 to 2 weeks. UC IPM says eggs hatch in about 10 to 15 days at room temperature. A second round catches what hatched.

How Long Does It Take for Bed Bug Eggs to Die?
It depends on the method. Here are the sourced times:
| Method | Time to kill eggs | Source |
|---|---|---|
| Steam, 130°F or more | On contact, where it reaches | EPA, University of Kentucky |
| About 131°F | Almost right away | Kells and Goblirsch, 2011 |
| About 118°F | About 72 minutes | Kells and Goblirsch, 2011 |
| Dryer on high | 30 minutes | Texas A&M AgriLife |
| Pro heat, whole room | 130°F for 3 hours or 140°F for 2 hours | UC IPM |
| Freezer at 0°F | 3 to 3.5 days | EPA, Olson et al., 2013 |
| Freezer below about minus 4°F | About 48 hours | Olson et al., 2013 |
| Encasement | Eggs hatch, trapped nymphs starve over time | UC IPM |
Any egg you miss hatches within about 1 to 2 weeks at room temperature, so timing your follow-up matters more than any single product.
How do you know the eggs are dead? You usually cannot tell by looking. The practical test is time: if no new nymphs, bites or fresh spots show up for several weeks, and interceptor cups stay empty, the eggs did not survive.
What Does NOT Kill Bed Bug Eggs
Common mistakes, several of which the EPA calls dangerous:
Does not kill eggs, per Texas A&M, and the EPA says it has caused numerous house fires.
The spray does not reach the cracks where eggs are. Too many can cause a fire or explosion.
Does not kill eggs and can harm your lungs. Use only registered, labeled products.
The EPA warns these can make your home dangerous and unlivable.
A thermostat, space heater or fireplace cannot reach killing temperatures safely.
A few hours, or a freezer warmer than 0°F, lets eggs survive. Eggs are the most cold-hardy stage.
- Washing in cool or warm water only. The dryer does the killing, so never skip the hot dryer cycle.
- Treating once and stopping. Eggs you missed hatch in 1 to 2 weeks. Plan the second round on day 1.
Safety first: if anyone feels dizzy, sick or has trouble breathing after a pesticide was used, get them to fresh air and call Poison Control at 1-800-222-1222, or 911 in an emergency. Bring the product label with you.
How Professionals Kill Bed Bug Eggs
Our technicians can heat every crack in a room, and UC IPM notes the most effective bed bug pesticides are available only to commercial applicators.
K9 inspectionTrained dogs sniff out live bugs and eggs.
Heat treatmentRooms held at 130°F to 140°F for hours, killing eggs in 1 visit.
Chemical treatmentLabeled products plus a follow-up timed for hatching eggs.
For severe or whole-building problems, another option is fumigation with sulfuryl fluoride. UC IPM says it is available for bed bugs in California but leaves no residual protection, so it is usually paired with other steps.
In California, only licensed pest control operators may do this work. The Structural Pest Control Board licenses pest control operators, and you can check a license on its website. Ask us how we handle eggs and when the follow-up happens.

If You Rent in California
California’s bed bug law, AB 551 (California Civil Code sections 1954.600 to 1954.605), covers rentals:
- A landlord cannot show, rent or lease a vacant unit they know has a current bed bug infestation.
- Landlords must give tenants written information about bed bugs and how to report them.
- After a pest control inspection, the landlord must share the findings with affected tenants in writing within 2 business days.
- Tenants must cooperate with inspection and treatment.
Report eggs or bugs to your landlord in writing, with photos, and keep a copy. In an apartment, killing eggs in your own unit is not enough if bugs keep coming from next door.
Frequently Asked Questions
What kills bed bug eggs?
Heat kills bed bug eggs most reliably. A dryer on high for 30 minutes, steam of at least 130°F and professional whole-room heat all work. Freezing at 0°F also works but takes about 3 to 4 days.
What kills bed bug eggs instantly?
Direct steam of at least 130°F at the surface kills eggs on contact, but only the ones it reaches. Nothing kills every egg in a room instantly.
What temperature kills bed bug eggs?
University of Minnesota research found eggs die almost right away at about 131°F and need about 72 minutes at about 118°F.
Does freezing kill bed bug eggs?
Yes, if it is cold enough for long enough. Use a sealed bag in a freezer at 0°F, checked with a thermometer, for at least 3 to 3.5 days. A few hours, or a freezer warmer than 0°F, is not enough.
Does rubbing alcohol kill bed bug eggs?
No. Texas A&M says alcohol-based sprays do not kill eggs, and the EPA says rubbing alcohol has caused numerous house fires when used against bed bugs.
Does diatomaceous earth kill bed bug eggs?
No. Desiccant dusts dry out bugs that crawl through them, and eggs do not crawl. Never use pool or food grade diatomaceous earth.
Does vacuuming get rid of bed bug eggs?
Only a few. Eggs are glued to surfaces, and Texas A&M says vacuuming is not very good at removing them. Scrape seams first and vacuum often.
How do you kill bed bug eggs before they hatch?
Dry fabrics on high heat, steam seams and cracks, freeze small items at 0°F, encase the mattress and box spring, then repeat in 1 to 2 weeks to catch any eggs you missed.
