Bed bugs are nasty little critters that are extremely difficult to get rid of once they’ve made your house their home. Of course, in order for bed bugs to survive, they need a food source.

How long can bed bugs live in an empty house?
Well, this depends on a few factors, including how long they have to go without any human interactions, as well as whether or not there are any replacement food sources for them to feed on between human meals. The temperature of the home can also affect how long the bed bugs live. For more information on how long bed bugs can survive in a vacant home, keep reading.
Bed bugs Trusted Source Bedbugs - Symptoms and causes - Mayo Clinic Bedbugs are small, reddish-brown blood-sucking, wingless insects. Bedbug bites usually clear up without treatment in a week or two. Bedbugs aren’t known to spread disease, but they can cause an allergic reaction or a severe skin reaction in some people. www.mayoclinic.org are small insects with red-brown coloring that are known to live in the nooks and crannies of mattresses, box springs, headboards, and bed frames. They can also be found in nightstands and other furniture around beds. You may even find them beneath peeling paint or wallpaper, in the carpeting around baseboards, in electrical outlets or light switch plates, or the seams of upholstered furniture. They wait patiently until nighttime when humans climb into bed to sleep. Then they emerge, biting into the skin to drink blood.
Though bed bugs can be found in homes, they more frequently infest hotels, hostels, hospitals, and homeless shelters. This is because these buildings have visitors coming in and out much more often, bringing the bugs in with them. In fact, if you’ve noticed a new infestation of bed bugs in your home, they were likely brought in from one of these places, riding along in a suitcase, backpack, or even in your clothing.
Once the bed bugs have made their home in a building, they are quite difficult to eradicate. Of course, if there is nothing for them to feed on, there is the chance that bed bugs can die on their own. The following factors can contribute to their demise.
Bed bugs have a much longer lifespan than you may expect. Their life cycle Trusted Source Bed bugs Bed bugs (Cimex lectularius) were almost completely removed from North America due to mass treatments with highly toxic insecticides that are no longer in use. extension.umn.edu begins when a female bed bug lays her eggs, which can number between 200 and 250 and can hatch in 6 to 10 days. The high amount of potential offspring and fast hatching time is just part of the reason why bed bugs are so difficult to remove once they’ve taken up residence in your home.
The hatched bed bugs are in the nymph stage, which is when they begin feeding on the humans, pets, or rodents inhabiting the home. The nymphs must feed at least once before they shed their exoskeleton, the process of which is called molting. They may even feed once each day. When you consider how many eggs there were, it’s no wonder their bites are so easily noticed on your skin. Nymphs molt five times during this stage of their life. If they do not get the blood required to get through all of the molting sessions, they won’t survive, though it can take up to 2 months for the lack of food kills them.
After the fifth molting stage, a bed bug reaches the adult stage, which is when these pests are the hardiest. Though they still need to feed on blood, during this stage of life a bed bug can go semi-dormant, which is a form of hibernation that allows the bed bugs to slow their metabolism to reduce energy use until their next feeding. In fact, they can live up to a year and a half this way before they starve to death.
Due to their long lifespan, bed bugs can survive in an empty house for much longer than you may expect. Of course, there is another factor that can reduce their lifespan, namely the temperature of the house they are inhabiting. Bed bugs prefer warm temperatures but can’t handle weather that is excessively hot or cold.
In fact, these nasty little critters can only handle a temperature of 25 degrees Fahrenheit or lower for a few days. Any longer than that and the cold will kill them. If you happen to live in a cold climate and discover bed bugs in your home during the winter months, you may be able to eliminate them using those low temperatures. Simply turn off the heat and leave your home for 2 to 3 weeks. After this amount of time in the cold, the bed bugs should die on their own.
Increasing the temperature of your home can also have the same effect on bed bugs. If the temperature of your home reaches 113 degrees Fahrenheit or higher, the bed bugs will die. This will also be quite warm for you and your family, so you may want to vacate the home for a week or more to stay comfortable while you eliminate the unwanted pests.
Humans are a bed bug’s favorite source of food, though they will feed off other animals if there are no people nearby to nibble on. As long as they have contact with something that bleeds the same way humans do, they can still feed. Such alternatives can include pets, like dogs, cats, rabbits, or even hamsters.
Even in a home where the owners and pets have left for a few days or weeks or in a vacant home, there could also be rodents living there that the bed bugs could feed on. This includes mice, rats, or anything else living in your home. If there are even a few of these around, a bed bug can survive for several months without a single human to nourish them.
Since bed bugs need the exact right conditions to die off on their own, including a lack of food and either excessively hot or cold temperatures, it is quite rare for you to rid your home of them without some help.
