There are a lot of myths and misinterpretations about bed bugs, like do bed bugs live outside? Where? And for how long? I’m going to answer all these questions in this article. Bed bugs are parasites that need blood to survive. One of the most common is that bed bugs can survive in any condition. This is not true, as they need a blood meal to survive and cannot reproduce without one.

Bed bugs cannot survive outside in extreme climates. They will not be able to thrive in extreme cold, but they can live in room temperature that is lower than what is comfortable for humans.

Where do bed bugs come from in nature?

Bed bugs come from areas that are infested with them. This can be from other people, as they often hitch a ride on clothing or luggage. Bed bugs are drawn towards the body temperature.

They can also come from areas where there is a lot of clutter or dirt, as this provides the perfect environment for them to live and thrive.

Do Bed Bugs Live Outside? Where? And For How Long?

Bed bugs are not picky as to where they live and can thrive in a warm, dark environment. As long as there is an available blood meal, bed bugs will be content and can live outside of their host for up to 18 months.

How far can bedbugs travel outside?

Bedbugs can travel up to 20 feet per day for food or a place to live. They may leave their neighboring property and enter another building to find these things. Bedbugs are attracted to carbon dioxide and heat, so they may visit their hosts even after leaving the property.

Since bedbugs can travel on clothing, luggage, and soil, it is important to take measures to prevent them from entering your home in the first place.

One way to do this is by using effective pesticide treatments to eliminate any bedbugs that may be present. Keeping clutter and other potential hiding places out of the home is also important.

Why do bed bugs try everything to get inside your home?

Bed bugs will try everything to get into homes where people are sleeping to feed on them. If they cannot find a human host, they feed on other animals but prefer human blood. These pests cannot live without their blood meal.

Bed bugs can be attracted to homes by the smell of people or pets. They can also live near people if they find a safe place. This is why it is important to keep your home clean and free of clutter so that bed bugs have a harder time finding their way inside.

Do Bed Bugs Live Outside? Where? And For How Long?

Yes, bed bugs do live outside. They can be found in various places where they feed on human blood. They are often drawn to areas near people, such as residences, hotels, and hospitals.

However, they can also be found in other locations where they may have access to blood meals.

Bed bugs are creatures of habit and tend to stick to a specific routine. During the day, they will go into hiding and only come out at night to feed on blood. This means that if you’re seeing bed bugs during the day, there’s likely an infestation somewhere nearby.

They can live up to a year without feeding, which means they can live outside the host for an extended period. They prefer warm and humid environments, so they may be more likely to live in areas like the Southern United States. 

Where do bedbugs hide outside?

Since bed bugs are excellent survivors, they can live outside your home for some time. They often hide in outdoor buildings, furniture, and cars. If the weather gets too cold, they will try to escape by moving into any vehicle.

Bedbugs love to colonize reclaimed or repurposed wooden beams in raised vegetable beds. This will depend on a few factors, such as the weather and the environment where they are hiding.

Who are the enemies of bed bugs in the outside environment?

Bed bugs have some natural predators that will eat them, including spiders, centipedes, and beetles. However, these predators are not a reliable bed bug control solution because it is unlikely they can eliminate an entire outdoor colony.

In addition, bed bugs can live outside for extended periods if the conditions are right; they can survive in cold weather and even hibernate.


There are a few different types of spiders that will eat bed bugs. The two most common are the cobweb spider and the running crab spider. These spiders are able to hunt their prey by running quickly across floors and ceilings, which makes them good at escaping detection.


Lizards are a common predator of bed bugs and can help to control their population. However, the correct living conditions for lizards are uneven, as they require a certain level of humidity and warmth. If the environment is not suitable, lizards may move away or die.

What factors affect the bed bug life span while they live outside?

Food deprivation

Biting insects, such as bed bugs, need blood to reach adulthood. If a female bed bug doesn’t have access to blood, she won’t be able to lay eggs. This means the bed bug population will decrease over time if they can’t find food.

Bed bugs can survive without a single blood meal, but they will become lethargic and stop breeding.

Extreme temperatures

Adult bed bugs will die when exposed to temperatures above 120 degrees Fahrenheit, which is also known as the killing temperature for bed bugs. They can also not tolerate temperatures below 0 degrees.

They can’t handle the extreme pest control heat treatment, so they will be eradicated in no time. Thus, these pests generally live in warm environments but can survive in the desert by hiding in cracks and crevices.

However, if the temperature dips below freezing, the bed bugs will die in cold temperatures. Due to this reason, bed bugs can be killed by heat remediation treatment.

How do bed bugs come to live in your garden?

Bed bugs are brought to a new location by humans. They can hitch a ride on clothing, luggage, or furniture. They will look for a blood meal once they are in a new place.

If there is no human around, they may try to feed on other animals, but their preferred food source is human blood. Bed bugs can be driven away from an inhabited building with a pest control bed bug consultation.

How long can a bedbug live without blood?

Bed bugs live for a long time without blood. They can go up to four months without eating. This is one of the reasons they are so difficult to get rid of—they can hide in small places and go for long periods without being noticed.

However, bedbugs have many natural enemies, including other insects and animals. And while some of these may create pests of their own, most help keep bedbug populations under control.

Are bed bugs photophobic?

Bed bugs are photophobic. This means that they will generally avoid areas where there is a lot of light. They tend to prefer dark, secluded areas where they can hide and feed undetected.

They feed at night on human blood meal when the host is asleep, making feeding easier as the person is unaware.

Bed bugs also need to digest and lay eggs in a dark place, which makes harborages darker and provides more security for them. As a sign of infestation, the bed bug excrement is dropped near the food availability.

How easily do bed bugs spread?

Bed bugs are notorious for their ability to spread quickly. They can be picked up from virtually any surface and often seem to arise from nowhere.

Once bed bugs are in a home, they can spread quickly from room to room and even floor to floor. They are very agile and fast-moving, so they can hitch a ride on clothing or luggage.

In fact, they can travel up to 100 feet in a single night which is an amazing survival ability feature shown by these pests!

They’re attracted to blood and leave tell-tale blood spots on the sheets. These pests will crawl rapidly in the direction of any nearby blood source. Once they’ve established themselves in a location, they can be very difficult to eradicate.


Although bed bugs can live outside, it is not a hospitable environment for them. They prefer to be close to humans to feed and will only live outside if necessary. If you are dealing with a mobile bed bug infestation, it is best to consult a professional to help you eliminate them with expert bed bug treatments.

Bed bugs are masters of survival and can live in difficult conditions, so it is important to take the necessary precautions to eliminate them.
