how long can a bed bug survive without food

by food

Bed bugs are resilient pests that can survive for up to a year without food. This makes them difficult to eradicate from homes, hotels, and other places where they may live. Bed bugs feed on human blood and will go without food for long periods of time in order to find a suitable host. While the exact amount of time a bed bug can survive without food varies, most experts agree that they can survive up to 12 months or longer depending on environmental conditions.Bed bugs can survive for up to six months without food. However, they become increasingly more active in search of a food source as time passes, putting them at greater risk of being discovered.

Factors Affecting Bed Bug Starvation

Bed bugs are small, parasitic insects that feed off the blood of their hosts. As such, they can survive for long periods without food if necessary. However, starvation is still a potential threat to these pests and there are several factors that can affect their ability to survive without meals.

The first factor is the availability of food. If bed bugs find themselves in an environment where there is no access to a host, they will quickly become hungry and begin to starve. In addition, the availability of food will determine how long they can survive without eating. The more food available, the longer the bed bug can live without eating.

The second factor is temperature. Bed bugs thrive in warm temperatures and prefer temperatures between 70-90 degrees Fahrenheit (20-32 degrees Celsius). If temperatures drop too low, bed bugs may become lethargic and incapable of searching for food. As such, cold temperatures can significantly reduce their ability to survive without meals.

Lastly, the amount of moisture in the environment can also affect bed bug starvation. Bed bugs need some moisture to stay hydrated and if the air is too dry they will eventually die from dehydration. Additionally, extremely humid environments can also be problematic as bed bugs cannot swim and may drown in overly humid areas.

In conclusion, there are several factors that can affect bed bug starvation including availability of food, temperature and moisture levels in the environment. Understanding these factors can help individuals better control bed bug infestations by providing adequate conditions for them to thrive or ensuring that conditions do not become unfavorable for these pests.

Life Cycle of a Bed Bug

Bed bugs have a simple life cycle, composed of five distinct stages: egg, nymph, five nymphal stages, and adult. In ideal conditions, it takes a bed bug approximately one month to complete its life cycle from egg to adult.

Egg: Female bed bugs lay eggs that are about the size of a grain of salt and white in color. They are laid in clusters of up to 200 and in areas close to where the bed bug feeds. The female will lay one to five eggs each day and can produce three or more generations each year depending on the temperature and availability of food.

Nymph: The eggs hatch into nymphs within one week to 10 days after being laid. Nymphs are nearly colorless but become browner as they feed. Newly hatched nymphs will feed immediately but do not become reproductive until they reach their fifth and final stage of development.

Five Nymphal Stages: As the nymphs mature through five stages, or instars, they shed their exoskeleton or molt through a process called ecdysis. Each molting requires a blood meal before it can occur. Bed bugs can survive for several months without feeding but require blood meals for development from one stage to the next.

Adult: Once it has reached its fifth instar, the bed bug is now an adult capable of reproduction. Adults are about ¼ inch long, oval in shape and brownish-red in color with small antennae visible at the front end of their bodies. Adults live for 10 months or more if they have access to food throughout their lives.

After reaching adulthood, male bed bugs will mate with multiple females over several days while females will mate just once in their lifetime producing several hundred eggs over their lifetime before dying shortly after laying her last batch of eggs.

What Do Bed Bugs Eat?

Bed bugs are parasitic insects that feed on human and animal blood. They are small, flat, reddish-brown bugs that range from 1 to 7 millimeters in size. Bed bugs can be found in a variety of places, such as mattresses, furniture, carpets, baseboards, and even in electrical outlets. They are active mostly at night and tend to hide during the day.

Bed bugs primarily feed on human blood. They are attracted to the carbon dioxide we exhale and the warmth of our bodies. After a meal, they can swell up to twice their normal size and become darker in color. Feeding usually takes place while people are asleep or inactive; it only takes about 5 minutes for a bed bug to take its meal. Bed bugs can also feed on other warm-blooded animals such as cats and dogs, but they prefer humans due to our higher body temperature.

In addition to blood meals from humans and other warm-blooded animals, bed bugs may also feed on dried skin flakes or shed skins found around bedding areas. This type of feeding is more common when food sources are scarce or when people have been away from their homes for an extended period of time. Bed bugs may also feed on other insects such as cockroaches if available in their environment.

What Happens When Bed Bugs Don’t Get Enough Food?

Bed bugs are highly adapted to survive in almost any environment. They are adept at finding food sources and can go for months without a meal. But what happens when bed bugs don’t get enough food?

When bed bugs don’t get enough food, they become weak and sluggish due to a lack of nutrition. This makes them far less capable of reproducing, meaning their population will dwindle over time. They may also enter a state of hibernation, where they remain inactive until a suitable food source is located.

Without enough food, the eggs laid by female bed bugs will not hatch. Even if the eggs do hatch, the young nymphs will be unable to grow and develop as they should since there’s not enough nutrition available. This can significantly reduce the chance of survival for the newly hatched nymphs.

Another consequence of not having enough food is that it can weaken the immune system of bed bugs, making them more vulnerable to diseases or other parasites. This can lead to an even greater reduction in their population over time as more and more individuals succumb to infection or infestation from other pests.

Overall, bed bugs need a reliable source of food in order to survive and propagate their species. Without adequate nutrition, their numbers will quickly dwindle and they may even enter a state of hibernation until such a time as when they find an appropriate meal again.

Signs of Starvation in Bed Bugs

Bed bugs are one of the most common household pests and are known to cause a multitude of problems. They can cause skin irritations, spread diseases, and destroy furniture. But when bed bugs start to starve, they can cause even more damage. The signs of starvation in bed bugs can be difficult to detect, but it is important to know what to look for in order to prevent further harm.

The most common sign of starvation in bed bugs is a decrease in activity. Bed bugs will become sluggish and less active as they start to starve. This is because they are not able to get enough nutrients from their food source. They may also be less likely to move around or feed on humans or pets.

Another sign of starvation in bed bugs is an increase in size. As the insects begin to starve, their bodies will start storing fat for energy which can result in them becoming larger than usual. This may be difficult to detect since bed bugs tend to move around a lot and it may not be obvious that they are growing.

The third sign of starvation in bed bugs is changes in color and texture. As the insects become deprived of nutrients, their exoskeletons may become darker or lighter than normal and they may start appearing rough or flaky due to dehydration.

Finally, signs of starvation in bed bugs may also include an increase in aggression or biting behavior as they become desperate for food sources. This can lead to more frequent and painful bites on humans or animals which should be treated immediately by a professional pest control company if necessary.

Starvation is one of the most dangerous aspects for bed bugs as it can lead to serious health complications and even death if left untreated for too long. If you suspect that your home has been overrun with these pests, it is important that you contact a professional pest control company right away before the situation gets worse.

How Long Can a Bed Bug Live Without Feeding?

Bed bugs can survive up to a year without feeding, depending on the temperature of their environment. They can live for several months in colder climates and even longer in warmer climates. Bed bugs are also known to go into a state of diapause, where they can remain dormant for long periods of time, even up to one year without food. However, this is not a preferred state for them and they will eventually seek out food if it is available.

The bed bug’s lifespan is heavily dependent on its environment and the temperature that it’s exposed to. In ideal conditions, an adult bed bug can live for up to 18 months without feeding. In cooler climates, bed bugs can survive for several months without feeding; however, their activity levels decrease significantly as the temperature drops below 60 degrees Fahrenheit (15 degrees Celsius).

In addition to temperature, the availability of food also affects the bed bug’s ability to survive without feeding. If there is no food source available, bed bugs will enter into a state of diapause in order to conserve energy and extend their lifespan. During this time, they may not feed or reproduce until conditions become more favorable again.

In conclusion, bed bugs can live up to one year without feeding depending on their environment and the availability of food sources. Although they may enter into a state of diapause in order to conserve energy and extend their lifespan, this is not an ideal condition for them and they will eventually seek out food if it is available.

Reducing the Risk of Starvation in Bed Bugs

Bed bugs are a common pest problem in homes and businesses, and they can be difficult to get rid of. Although there are many ways to get rid of bed bugs, one of the most effective methods is to starve them out. Unfortunately, bed bugs can survive for long periods without feeding, so it’s important to take steps to reduce the risk of starvation in order to ensure that your bed bug problem is eliminated. Here are some tips on how to reduce the risk of starvation in bed bugs:

Remove all sources of food: Bed bugs feed primarily on human blood, so it’s important to remove any potential sources of food from your home or business. This includes removing clutter that could provide hiding places for bed bugs and sealing any cracks or crevices where they may be hiding. It’s also important to regularly vacuum and steam clean mattresses and furniture where bed bugs may be present.

Limit access to food: If you suspect that you have a bed bug infestation, it’s important to limit access to food sources as much as possible. This means not allowing anyone other than yourself or family members into your home or business who might potentially carry bed bugs with them. Additionally, make sure that all food containers are tightly sealed so that bed bugs cannot feed on them.

Use natural predators: There are several natural predators of bed bugs that can help reduce their population in your home or business. These include spiders, mites, beetles, and other insects that feed on bed bug eggs and larvae. It’s important to note that these predators will not eliminate a population entirely; rather, they will help keep their numbers under control.

Use insecticides: Insecticides can also be used as part of an integrated pest management strategy for eliminating a bed bug infestation. Insecticides should only be used as directed by a professional pest control company and should not be used around humans or pets unless absolutely necessary.

By taking steps such as these, you can help reduce the risk of starvation in bed bugs and ensure that your infestation is eliminated quickly and effectively.


Bed bugs can survive for several months without food, but their lifespans are significantly reduced. Without a blood meal, bed bugs will eventually die due to starvation and dehydration. It is important to take the necessary steps to prevent and treat bed bug infestations as soon as possible. By reducing the number of bed bugs and removing their access to food sources, you can reduce the amount of time they are able to survive without a blood meal.

To ensure that your home is free from bed bugs, it is important to regularly inspect for signs of infestation and contact a professional pest control service if you find any evidence of an infestation. Taking these steps can help reduce the amount of time that bed bugs are able to survive without food, allowing you to keep them from spreading further in your home or elsewhere.
