Bedbug endurance abilities

Whether they can survive in water or not, this depends on a few factors like time, depth of the water, type of the water and its temperature. Encounter all those reasons that influence their survival. No doubt, Bed bugs are experts in surviving but you can kill them with some techniques. It’s very hard to stop them from living with easy methods. Some factors responsible for contributing to their survival include the following-


Bed bugs can survive in water if they are under water for a very short period. Most of them will survive but few die after 24 hours of being in the water. They are considered stubborn. Some experiments even showed that they live for a year without being fed. This surprising fact means it’s hard to determine the exact survival time in the water.

Water can be either boiled or hot, salty or sweet, and so on. Bed Bugs have the potential to survive by gaining atmospheric air that they can also get without floating. Bed bugs can float on the water when they are not fed. The surface tension of the water helps them in floating or else, their chances of drowning are high. The absence of surface tension or increased weight of the bed bug will not let it float. This is the case when some of them may die. Still, a tiny fraction of them will thrive even after being in the water for a day. The temperature of the water is extremely important. It will determine if the bed bugs will die or stubborn enough to live again.

Duration as we said, matters a lot for their survival. Unless and until they have access to atmospheric air, Bed bugs will thrive.

Cold Water

It is nowhere mentioned that cold water can kill Bed bugs. However, drowning them into the cold water change this scenario. Washing your bed in the washing machine with cold water can show no result. If you somehow increase your washing machine power to let it work for 24 hours then the probability of killing bed bugs is high. Otherwise, it’s impossible to use cold water to kill them. You can let them suffer for a while only and nothing else.


Boiling water is regarded as the best way to kill some insects. Many insects can die due to this. You just need to splash hot water on them and wait for a few seconds. It’s not right to be kind to everything when they become a problem for you. Keep them away from your life. Boiling water is dangerous to use for you. However, do you know how can you kill Bed Bugs without seeing them? This is something difficult to find them.


This is great to know Bed Bugs don’t have the capability of swimming in the water. You can experiment to check this fact. There is a 100% chance to find them drowning even in a small amount of water. Water enters into the pores of their body. This makes them impossible to inhale air. Even after going through all these, don’t expect them to die in a day. They need air like we do to thrive in different environments. In addition, being a lightweight creature only permits them to float.


Do you like to shower daily? Maybe you do and many of us like but Bed Bugs hate it. Taking your bed under shower will force them to escape it but they will go and hide somewhere else. It will be stupid to think that you can kill them in the shower. A small crack in the wall, towel, you don’t know where they decide to hide. So, don’t be foolish to try killing Bed bugs in the shower.

Laundry and detergent

A washing machine is such a place where Bed bugs struggle to survive. Water, temperature, and soap together act as a weapon to kill bed bugs. Their tolerance level for heat is extremely low. You have to let them go through several cycles to kill. According to research, all types of bed bugs can be killed by heating the water for up to 140F. Under 30 minutes, over 90% of them die. This can kill the eggs too. Reducing the temperature to 100F kills only nymphs and adults but not eggs.


Try as much as you can but you can’t stop them from hiding. In the rainy season, you will probably spend time at home with them without knowing they are around you. When you are sleeping, one of them will come and bite you. Rainy season produces no effect on Bed Bugs. Summer is the only season when they face a problem as the sun rays reach them. Keep in mind that they are extremely smart at hiding so this is also not ample. Yes, they can survive in the rainy season.
