Can Bedbugs Survive Outdoors?

Bedbugs are small, reddish-brown insects that feed on the blood of humans and animals. They have been a nuisance to human beings for centuries and can be found in all parts of the world.

While most people associate bedbugs with infestations in indoor spaces, such as homes and hotels, many wonder if they can survive outdoors. Today, we will explore the survival capabilities of bedbugs in an outdoor environment.


Survival in Different Temperatures

Bedbugs thrive in warm and humid environments, with temperatures ranging from 70 to 80 degrees Fahrenheit or 21 to 27 degrees Celsius. They have a hard time surviving in extremely cold or hot temperatures.

Therefore, it is unlikely that bedbugs survive outdoors in regions with very cold or hot climates. However, in moderate temperatures, bedbugs can potentially survive for several months without a blood meal.


Survival without a Host

Bedbugs rely on blood meals from humans or animals to survive and reproduce. Without a host, they can only live for about three to six months.

Therefore, if an infested item is left outdoors for an extended period, such as a mattress or furniture, it is possible for bedbugs to survive without a host. However, their survival rate decreases significantly, and they may not reproduce.


Outdoor Infestations

While bedbugs are unlikely to establish an infestation outdoors, it is impossible. Bedbugs can be transported through infested items or clothing, and may end up in outdoor spaces.

If they find a suitable hiding spot, such as cracks in wood or furniture, they can survive and potentially reproduce. However, without a constant blood meal, their population will decrease over time.


Attracting Factors

Bedbugs are attracted to carbon dioxide and warmth, which is why they tend to infest areas where humans or animals spend a lot of time. While outdoor spaces may not provide these attractants in abundance, there are still some factors that can draw bedbugs outdoors.

For example, if an outdoor space is near a heavily infested indoor area, bedbugs may migrate to that space in search of a new host.



Bedbugs are unlikely to survive long periods in an outdoor environment. However, they can potentially survive and reproduce if certain conditions are present.

It is essential to take necessary precautions and treat any infested items before bringing them into an outdoor space to prevent the spread of bedbugs. Regular pest inspection and maintenance of outdoor spaces can also help identify potential bedbug presence and prevent infestations.
