Kill those pesky pests with these DIYs
DIY treatments include high heat, bleach, alcohol, and diatomaceous earth.
Rubbing alcohol, salt, baking soda, and boric acid are not effective.
Certain essential oils repel bed bugs but won’t kill them.
Diatomaceous earth is an effective passive method of bed bug treatment.
Professional exterminators perform highly-effective whole-room treatments.
Bed bugs are ruthless invaders, and they’re notoriously tricky to eradicate since they reproduce quickly and are quite adept at finding places to hide.
So, what kills bed bugs instantly? Note that most targeted treatments can’t totally wipe out the insects, as they won’t reach any that are hidden deep within the cracks and crevices. For major infestations, you’ll likely need to enlist the skills of a local bed bug control specialist. In the meantime, let’s review some of the most popular DIY methods and whether they are effective at killing bed bugs.
If your bed bug problem doesn't resolve itself after implementing DIY removal methods, it's time to call in a professional exterminator. Don't hesitate to take pest control action to prevent the infestation from growing.
Check out these methods for getting rid of bed bugs quickly and permanently.
A temperature of 131 degrees Fahrenheit can kill adult bed bugs and eggs when exposed for at least 72 minutes, according to the NCBI report. Steam or hot water can be an effective treatment, but it can be difficult to sustain the high temperature for long enough.
You have several options when using heat to swiftly kill the bugs:
Put blankets, bedding, and clothes in a dryer on the hottest setting for a few hours. This is typically enough to kill bed bugs and their eggs.
Use a dedicated steam cleaning tool to reach all the crevices in mattresses and furniture. This is an excellent way to handle bed bugs, but you’ll want a heavy-duty steaming tool. Consider renting one if necessary.
Hire a bed bug pro to use professional-grade equipment to seal up a bed, couch or even an entire room and heat it to the right temperature so every pest dies inside.
Rubbing alcohol is somewhat effective at killing bed bugs, but isn’t likely to be effective at eradicating an infestation. A study performed by Rutgers University found that spraying bugs with a solution of either 70% or 91% isopropyl alcohol only killed a maximum of 50% of the insects. It also won’t kill any nymphs or eggs. What’s more, alcohol is highly flammable, so it’s not a safe choice for dousing your bed and belongings.
Diatomaceous earth is a popular non-chemical bed bug treatment that can be highly effective against the insects. This sharp, natural powder has an abrasive and dehydrating effect on bed bugs, which can kill them on contact. To use it, dust a light layer on mattresses, baseboards, furniture, and wherever else the insects may be hiding. Be sure to use food-grade diatomaceous earth so it isn’t toxic to children and pets.
Silica gels are powerful desiccants that absorb moisture from bed bugs. They’re safer to use in the home than pesticides and can be very effective at killing bed bugs up to two days after application. You can use silica gel treatments in combination with other practices to quickly kill the bed bugs and help ensure they don’t return.
Keep in mind that silica gel is a spot treatment and can’t remove infestations on its own. You can quickly kill bed bugs in a mattress, but the larger bed bug problem often needs additional steps and help from a professional exterminator.
Fumigation, house tenting, or bug bombs are a last resort option when an infestation has grown too widespread. Pest control management practices differ on the use of fumigation, with some suggesting it and some trying to avoid it. Overall, fumigation is more common for commercial buildings than homes. Powerful airborne pesticides from fumigation can cause health issues and even damage fragile materials. In some cases, bed bugs can burrow down far enough to survive and eventually return. Many local bed bug companies recommend heat remediation instead of fumigation. Heat is nontoxic, equally effective, and safer for residential homes.
Yes, bleach can kill bed bugs instantly. To use it, wash clothing and any other items you can fit in your washing machine with hot water, bleach, and detergent. Follow this with a cycle in the dryer at the highest heat setting possible.
To kill insects on contact, you can also mix equal parts hot water and bleach to create a potent spray. Take care not to splash any bleach on colored clothing or fabrics, and wear protective eyewear and gloves.
Lysol and similar disinfectants that have isopropyl alcohol, ethanol, or ethyl alcohol as an active ingredient can be very effective at killing bed bugs instantly. Since these ingredients have been proven to be lethal to the insects, using spray disinfectants can also kill bed bugs on contact, with the added benefit of disinfecting the area at the same time.
Vinegar can kill bed bugs due to its acetic acid, a potent and toxic ingredient. Acetic acid can damage a bed bug’s nervous system on contact, potentially leading to its demise.
Similar to bleach, hydrogen peroxide has the potential to kill bed bugs. However, while not as damaging as bleach, it still has the potential to discolor certain dyed fabrics and upholstery.
Pyrethroids such as Permethrin, desiccants, pyrroles, and other chemical insecticides are capable of killing bed bugs. However, there are some risks to using pesticides for bed bug treatment. They may take time to work, so they won’t kill bed bugs instantly. They’re also toxic to humans and animals, so they can be hazardous to use around children and pets.
There are a few eradication methods and household goods that won’t work well to kill bed bugs instantly. Check out the options to avoid:
Paint thinner is one of the classic suggestions to kill bed bugs, but it’s best to avoid it. While a bad infestation can make you feel desperate enough to try anything, don’t apply paint thinner to your mattress, furniture, or clothes. While it can kill bed bugs on contact, this powerful solvent is toxic and highly flammable. People have accidentally lit their beds on fire with this method—we do not suggest it.
While ammonia has been used as an ingredient in some bed bug sprays in the past, we don’t recommend it. These powerful chemicals can kill bed bugs on contact, but they invite similar problems as paint thinner. Ammonia fumes are toxic in high amounts and bed bugs can easily hide away from direct application, which is why the Environmental Protection Agency (EPA) and other agencies do not recommend using it. Heat applications are a safer and more effective way to kill bed bugs quickly.
Baking soda may be effective against bed bugs, since the powder can dehydrate their bodies. However, there’s no scientific evidence to support baking soda as a lethal treatment against the insects, so it isn’t ideal to use as your only method.
Boric acid is a stomach poison, and won’t kill a bed bug unless they ingest it. While this proves effective for many pesky insects, it’s not likely to work against bed bugs. Since bed bugs feed solely on blood, they probably won’t consume the boric acid dust.
While salt is effective at drying out snails and slugs, it won’t have the same impact on bed bugs. Diatomaceous earth will typically be a much more effective solution for killing bed bugs than salt.
While many of these methods can kill bed bugs on contact, wiping out an infestation is an entirely different story. Bed bugs hide in every nook imaginable, from your box spring to your electrical outlets, so it’s extremely difficult to reach every single insect for targeted treatments.
Bed bug extermination costs between $1,000 and $2,500 and is often the best route to go for serious infestations. If you want to get rid of bed bugs quickly and permanently, a professional exterminator has access to the most potent and widespread methods of eradicating all the bugs, nymphs, and eggs in your home.
Bed bugs and humans have been at odds forever: One reason is because our homes make perfect spots for these bugs to thrive and grow. It only takes a couple of bugs to start an infestation, especially if they’re ready to lay eggs. Unlike many pests, bed bugs are not attracted to decaying wood or similar materials, chemicals, or human food.
Here’s why bed bugs want to take up residence in your home:
Warmth: Bed bugs are attracted to warm areas, specifically the warmth of human bodies. That warmth also indicates the best spots on the human body to feed, which is why they congregate in areas we lay or sit frequently.
Carbon dioxide: Like many insects that feed on humans, bed bugs are attracted to the smell of carbon dioxide, which we produce whenever we exhale.
Other bed bugs: Bed bugs emit their own chemical signatures that can attract other bed bugs. That explains how they can easily congregate in the same hiding spots deep in the seams of a mattress or couch.
Dark bedding: It may sound odd, but bed bugs are attracted to color, especially colors that make it easier for them to hide. Dark and reddish bedding seems to be their favorite, while light-colored bedding is less likely to attract them.
Dirty laundry: Dirty laundry is filled with the traces of humans, which can attract new bed bugs looking for places to set up shop. A laundry hamper can be a popular gathering spot, especially if clothes haven’t been washed in a while.
There is very limited scientific evidence to support the efficacy of essential oils against bed bugs and they are very unlikely to kill the species. However, a 2021 study published by the National Center for Biotechnology Information (NCBI) found that compounds in essential oils like clove oil, lemongrass, citronella, and bergamot could repel the insects.
A temperature of 131 degrees Fahrenheit for 72 minutes will kill bed bugs. Research suggests several different ranges, but many suggest starting at 120 degrees Fahrenheit and maintaining that heat for at least two hours. Steam cleaning is an exception because steam comes so hot it can quickly kill bed bugs and their eggs, making it a good option for fast extermination.
It’s difficult to be sure bed bugs are gone, especially with DIY methods. Any treatment you use should also include dedicated beg bug traps to pick up stragglers and help you monitor how many are left. It usually takes around three weeks to clean up remaining bed bugs and make sure they aren’t returning any time soon. Hiring a bed bug exterminator can decrease the amount of time it takes to remove these pests.
Some natural applications are known to make bed bugs unhappy, like peppermint and tea tree oil. But bed bugs are tenacious and as long as there are sleeping humans around to feed on, they’ll stick around. It’s best to destroy them outright by using heat, steam, or fumigation methods.
It’s not fast, but you can tightly seal items and store them away for at least a few months, preferably an entire year. Bed bugs can’t survive that long without eating. However, this method takes significantly longer than other common eradication methods like heat treatments, steaming, or fumigation, so it’s not a first choice for homeowners.
It’s best to kill bed bugs on your mattress as quickly as possible, isolate any potentially infested belongings, and continue sleeping there. If you move to other locations, you could transfer bed bugs or draw them into new rooms as they search for you, making the problem worse. Consider sleeping in clothes that cover as much of your body as possible to avoid further bites.
