How Long Can Bed Bugs Live Without Food

Bed bugs are elastic. They can survive in varying temperatures from cold to extreme heat. They move quickly, especially at night, and have a flat surface that makes them easy to hide in cracks.

They can also survive without food. Many people wonder how long a bedbug can live without food. The answer may surprise you!

A fully grown bed bug can survive without breastfeeding for up to a year. This makes it very difficult to get rid of them. They may be hiding in your attic, interior walls, or under the bed, waiting for an opportunity to eat and disappear quickly without a trace.

No matter where you live in the world, you will probably find bedbugs somewhere near your home. Creatures are able to withstand temperatures. They have been found in the coldest winters in Canada to the hottest summers of India and the Middle East.

Creatures can hide among luggage, bags, and even clothing, moving from one place to another. The bugs reproduce quickly and may begin to invade within a few months. This poses a threat to bedbugs, especially in urban areas.

In many cases, bedbugs are infested with carpets and furniture without your knowledge. They always lived in the colonies. If you find one or two in your home, it is more likely that they will be numerous.

Bed Bugs do not eat natural waste or food scraps like many other domestic insects. Their mouths are designed to devour only blood. They cannot process the blood of other mammals and eat only human blood.

That means that when they invade your home, you and other family members are your main source of food.

There is a common misconception about bed bug feeding and many believe that insects only come out to eat at night. Although bed bugs are nocturnal animals, they can go out and eat whenever they are hungry.

Many people who get bedbugs in their homes try to starve themselves by reducing their access to food. They get special beds and furniture so they don’t have to sit. Some people close their homes and leave for a few weeks hoping that the bedbugs will die without food.

This does not work. Studies have shown that a fully grown insect can live up to 400 days without sucking. Since their mouths are not designed for food or anything else, this long absence without feeding seems hard to believe but is true.

There are a number of factors that determine how long bedbugs can survive without food. The first is the age of the bug.

The most obvious feature is the age of this insect. The life cycle of bed bugs involves five stages: from early hatching to adulthood. The bug should eat at least once during each stage before it can grow into the next stage of life. If the bed bug does not eat for a few weeks during each growth stage, it can die.

The length of time they can live without being fed increases during each stage of life. Once they have grown into full-grown adults, they can live for up to a year without food. Some studies even suggest that adult bed bugs can live up to 18 months without breastfeeding, provided that certain living conditions are favorable.

Another factor that affects their survival is the habitat of the bugs and the performance levels. Bed Bugs near the bed or other furniture have to move slowly to search for food. If bedbugs do not have to travel a lot, they can survive without food. Bedbugs who need to travel long distances to feed will need to get more.

Temperature is also important. In colder climates, bedbugs use less energy and stay asleep. At high temperatures, their bodies use a lot of energy and need to be fed more often in order to survive.

People living with bedbug infestations are bitten almost daily. They mistakenly think that the same bed bugs are eating them and that removing the food from the bed bugs, even for a few days, will help them get rid of the insects.

This is not true. A typical detoxifier only needs food once in ten or twelve days to stay active. The nymph feeds once a week to grow to the next stage. If you are bitten daily, then you may have an infestation of large insects on your hands.

Bed bugs do not grow as fast as other insects. An adult female bed bug lays one egg a day. It takes 10 days for an egg to hatch and it takes another five to six weeks for the bugs to develop into full-grown adults.

By comparison, a typical fly lays up to 500 eggs in three to four days. Female mosquitoes also lay many eggs every day.

What makes bed bugs so dangerous is that they grow so peacefully. You will not find that you have a problem until the colony becomes too big for you to control. A single bed bug infestation can be grown into a group of thousands of bed bugs within three months.


Bedbugs can also hide between luggage and furniture. They can break into your home and begin to spread in an invisible area while eating only occasional meals. Most people only realize that they have sleeping insects when the insects have already grown to twelve or more.

Restricting bed bug access to food can help reduce growth. However, it is not guaranteed to eradicate them as one adult bug can live for months, even a year without breastfeeding.
