Bed bugs can be a nightmare to deal with, but the good news is that water can be a powerful tool in their elimination. Water can kill bed bugs, but it's essential to understand the right way to use it.
Bed bugs are notorious for their ability to survive for months without food or water, but they can't withstand prolonged exposure to water. According to research, bed bugs can drown in as little as 2-3 minutes of submersion in water.
To effectively eliminate bed bugs using water, it's crucial to use a combination of techniques. This includes washing and drying bedding, clothing, and other items in hot water and high heat, as well as using a steam cleaner to kill bed bugs and their eggs.
Can Water Kill Bed Bugs?
Water can't kill bed bugs just by being in contact with it, they aren't allergic to water. You can't drown them in a shower, as the water may drain away too fast for them to drown.
Hot water, on the other hand, can kill bed bugs, but it has to be extremely hot - at least 120°F for several minutes. Using your washing machine on the hottest setting can be a smart first step for treating infested items.
Bed bugs are unlikely to be in your shower anyway, as they prefer places close to their host when they sleep and don't live on you or hide on your body.
Can You Kill?
Hot water can indeed kill bed bugs, but it has to be scorching hot - at least 120°F for several minutes. Using your washing machine on the hottest setting is a smart first step for treating infested items like sheets, pillowcases, and clothing.
You need to use high temperatures to make a difference, not just warm or lukewarm water. It's not a matter of just running a regular cycle.

Can Swim?
Bed bugs can't swim. They will drown in even a small amount of water.
Their bodies are light enough to float on the surface. However, they can't propel themselves to safety.
Bed bugs have short legs that are better for crawling and climbing. They maintain contact with the water, making it impossible for them to breathe.
They struggle to get out, eventually taking in water and dying.
Bed Bug Survival
Bed bugs can survive for a short time when submerged in water, but their ability to do so depends on the temperature of the water involved. Generally, they can endure cold temperatures far better than hot ones.
They can continue to live under icy conditions, but if exposed to heat above 131º F, it becomes lethal for all stages of bed bugs. This is why raising the temperature is more likely to be effective in eliminating them.
Bed bug eggs are particularly resilient and can remain viable even after being in the water for up to 24 hours.
Cannot Swim

Bed bugs cannot swim, which makes water a potentially deadly force against them. This is due to the structure of their body, which lacks the necessary appendages for swimming.
In fact, bed bugs are disadvantaged in aquatic environments. They may have a knack for floating on the surface tension of water, but if they get submerged, they succumb and drown.
Bed bugs will never go into water on their own, so you won't find them in your shower. They prefer places close to their host when they sleep, and they only feed at night.
Adult Can Survive Days
Adult bed bugs can survive in water for a few days. This is a crucial piece of information to keep in mind when trying to eliminate these pests.
Their survival depends on the temperature of the water, with adult bed bugs able to endure even longer than bed bug eggs. Bed bug eggs can last submerged in water for up to 24 hours.

Using hot water above 120°F when washing your bedding and clothing can be an effective way to eliminate bed bugs. Dry them on high heat for at least 30 minutes to ensure complete elimination.
Raising the temperature is more likely to be effective than submersion in tepid or cold water in getting rid of bed bugs.
Washing and Drying
Bed bugs cannot survive a washing cycle because of three factors: the water, the temperature, and the detergent. The water alone is fatal to them.
To kill bed bugs in the washing machine, wash launderable items at 140⁰ F or 60⁰ C for 30 minutes. This temperature is hot enough to kill all life stages of bed bugs.
Washing at 100⁰ F or 40⁰ C only kills the nymphs and adults and 25% of eggs, so it's best to wash and dry your garments at the hottest temperatures. This ensures that all bed bugs and their eggs are eliminated.
To prevent spreading bed bugs around your home, put launderable items in a plastic bag and dump them directly into the washer. This helps contain the infestation.
Here's a summary of the washing and drying process:
Drying clothes on high heat for at least 30 minutes is often more effective than washing alone because of the extreme temperatures. This helps eradicate bed bugs and their eggs.
Short Time Submersion Survival
Bed bugs can survive for a short time when submerged in water, but their ability to do so is heavily dependent on the temperature of the water involved.
This means that if you're trying to get rid of bed bugs by drowning them, you'll need to use hot water to increase the chances of success. Hotter temperatures typically decrease their survival rate, making it more likely that they'll perish.
Their inability to swim works against them, and they will drown if they encounter a substantial amount of water. However, their survival under such conditions isn’t indefinite and usually lasts up to 24 hours at best.
Bed bug eggs are even more resilient, remaining viable even after being in the water for up to 24 hours. This is why simply immersing the infested items or bedding in water may not be enough to eradicate these stubborn insects.
Use Heat to Clean Infested Clothing
To kill bed bugs in your clothing, you need to use hot water. Bed bugs can't survive temperatures above 131º F, which is why washing them in hot water is so effective.
Washing your clothes in hot water is a crucial step in getting rid of bed bugs. You should wash infested items in water at 140 degrees Fahrenheit (60 degrees Celsius) for 30 minutes to kill all bed bug life stages.
Drying your clothes on high heat is also essential. Extreme temperatures will eradicate bed bugs and their eggs, preventing future infestations.
Here's a summary of the temperatures you should use to kill bed bugs:
Remember to always follow the care instructions on clothing labels and take extra caution when treating delicate fabrics or items labeled as "dry clean only."
Elimination Methods
To kill bed bugs in the washing machine, use hot water above 120°F and dry clothes on high heat for at least 30 minutes. This is a crucial step in eliminating bed bugs from your home.
Washing and drying are your best friends when it comes to getting rid of bed bugs. The heat from the dryer can pick up the slack if your washer doesn't reach bed bug-killing temps.
To effectively eliminate bed bugs, first sort your clothes normally and then put each pile in separate plastic bags. This helps prevent spreading bugs to other areas.
Here are the steps to follow:
- Gather infested items: Clothing, bedding, curtains, anything soft that’s safe to wash.
- Transport in a sealed plastic bag: This helps prevent spreading bugs to other areas.
- Wash in hot water: Use the highest heat your washer allows.
- Dry on high heat: Dry items for at least 30 minutes.
Hot water is key to killing bed bugs in the washing machine. Use the highest heat your washer allows to ensure the best results.
Bed Bug Eggs and Survival
Bed bug eggs can survive for up to 24 hours in water, making it a less effective method to get rid of them.
The ability of bed bug eggs to withstand water is a testament to their remarkable resilience. They can remain viable even after being submerged for an extended period.
While bed bug eggs can survive for 24 hours in water, bed bugs themselves cannot swim and will ultimately drown if submerged in a substantial amount of water.
Their inability to swim and their tendency to drown in water is a crucial aspect to consider when trying to eliminate them.
Hotter temperatures can decrease the survival rate of bed bugs in water, causing them to perish once their body temperature reaches certain extremes within a watery environment.

CO2-Emitting Device for Insect Attraction
Using a CO2-emitting device can help attract bed bugs towards a water container, making it easier to drown them.
Bed bugs are drawn to the carbon dioxide we exhale, which indicates the presence of a potential host.
Placing a small bowl filled with yeast and sugar near the container can entice bed bugs to move towards the source of CO2.
Regularly replenishing the CO2-emitting device ensures its attractiveness throughout the process.
This technique can enhance the effectiveness of drowning bed bugs by enticing them to approach and potentially fall into the water.
