Bed bugs are notorious for being resilient pests that can invade your home and cause a lot of trouble. But how long can bed bugs live in an empty house? If you’ve been away from your home for an extended period or if you’re planning on leaving your house vacant, it’s crucial to understand how long these pests can survive in an uninhabited environment. This article will explore the lifespan of bed bugs in an empty house, how they survive, and the steps you can take to prevent or eliminate them.
What Are Bed Bugs?
Bed bugs (Cimex lectularius) are small, reddish-brown insects that feed on the blood of humans and other animals. They are notorious for hiding in crevices and cracks in your home, typically near sleeping areas. Bed bugs are nocturnal, emerging at night to feed and retreating to hidden spots during the day.
Despite their name, they are not limited to beds and can be found in other places, such as furniture, walls, and carpets. These pests are notorious for being difficult to detect and can be challenging to eliminate once they infest your home.
3. How Long Can Bed Bugs Live in an Empty House?
Bed bugs can survive in an empty house for a considerable amount of time, but their lifespan depends on various factors. In a vacant home without a food source, bed bugs can live anywhere from 2 to 6 months, and in some cases, they can survive even longer. They are incredibly resilient pests that can go for weeks without feeding, allowing them to wait for the opportunity to find a new host.
However, once the temperature drops or the environmental conditions become less favorable, their metabolism slows down, and they can survive in a dormant state until they have access to a host again. In optimal conditions (e.g., a mild temperature and a steady source of blood), they can thrive for longer periods.
4. Factors Affecting Bed Bug Lifespan in an Empty House
Temperature
Bed bugs are highly sensitive to temperature. In warmer conditions (around 70-80°F), bed bugs are more active and can live longer. If the house becomes cold or the temperature drops significantly (below 50°F), bed bugs may enter a dormant state, significantly extending their survival time.
Availability of Food
The primary food source for bed bugs is human blood. In an empty house, without access to a blood meal, bed bugs will eventually die. However, they can survive for several months without feeding, especially if they are hiding in places with lower temperatures or are in a dormant state.
Humidity
Bed bugs can also be affected by humidity levels. Dry conditions can lead to desiccation (drying out), which can decrease their lifespan. On the other hand, higher humidity levels can prolong their life, as they are less likely to dry out and more likely to remain in a state where they can wait for the next feeding opportunity.
Life Cycle of Bed Bugs
The life cycle of a bed bug—from egg to adult—can vary depending on environmental conditions. In optimal conditions, bed bugs can mature in about 5 weeks. However, if the temperature is cooler or food is scarce, the process can take longer. The bed bug’s eggs are particularly resilient, as they are protected by a tough outer shell. They can survive for weeks, allowing the infestation to restart once conditions improve.
Signs of Bed Bug Infestation
Even in an empty house, you should still check for signs of bed bug infestation. Common signs include:
- Blood stains on bedding or furniture.
- Dark spots (fecal stains) on walls, furniture, or bedding.
- Shed skins from nymphs or adult bed bugs.
- A musty odor from bed bug pheromones.
Regularly inspecting for these signs is essential, even in a vacant home.
How Bed Bugs Survive in Empty Houses
Bed bugs are highly adaptable and can survive without a food source for extended periods. They hide in cracks, crevices, furniture, and even behind wallpaper, where they remain undisturbed. In an empty house, bed bugs can survive by:
- Entering a dormant state when food is not available.
- Staying in hidden places that protect them from predators and environmental changes.
- Slowing down their metabolism to conserve energy until food becomes available again.
Can Bed Bugs Live Without a Human Host?
While bed bugs primarily feed on human blood, they can also feed on other animals like pets, rodents, or birds. If an empty house has other animals present, bed bugs may still find food sources. However, if the house is completely devoid of any living creatures, the bed bugs will eventually starve.
How to Prevent Bed Bugs from Infesting Your Home
Prevention is key to avoiding a bed bug infestation. Some essential prevention tips include:
- Seal cracks and crevices around doors, windows, and walls.
- Use bed bug-proof mattress covers to protect against infestations.
- Inspect secondhand furniture and mattresses before bringing them into your home.
- Keep the home clutter-free to reduce hiding places for bed bugs.
How to Get Rid of Bed Bugs in an Empty House
If you suspect a bed bug infestation in an empty house, here are the steps you can take to eliminate them:
- Thoroughly clean and vacuum all surfaces, including floors, walls, and furniture.
- Use heat treatment (above 120°F) to kill bed bugs and their eggs.
- Apply insecticides designed for bed bugs.
- Hire a professional pest control service if the infestation is severe.
10. Bed Bug Control Tips
To ensure you effectively eliminate bed bugs, consider these tips:
- Repeat treatments if necessary, as bed bug eggs may hatch after the first treatment.
- Monitor the area for any signs of recurring infestations.
- Consider using encasements for mattresses and box springs.
Common Myths About Bed Bugs
Here are some common myths about bed bugs:
- Myth #1: Bed bugs only live in dirty homes.
- Fact: Bed bugs can infest any home, regardless of cleanliness.
- Myth #2: Bed bugs can fly.
- Fact: Bed bugs are wingless insects and cannot fly.
The Importance of Professional Pest Control
If bed bugs are discovered in your home, professional pest control services are highly recommended. Bed bugs are challenging to eradicate without the right tools and expertise. A professional pest control technician can identify the infestation’s extent and use effective treatments to eliminate the pests.
How to Check for Bed Bugs in an Empty House
Inspect common hiding places for bed bugs, including:
- Mattress seams and box springs.
- Furniture cushions and cracks.
- Baseboards and behind-the-wall hangings.
- Electrical outlets and appliances.
Use a flashlight to look into these spaces for visible bed bugs or signs of infestation.

Conclusion
Bed bugs are resilient creatures that can survive for months in an empty house, particularly if they have access to a stable environment with minimal disturbance. While they can endure for some time, their ability to thrive without a blood meal is limited. Understanding how long bed bugs can live in an empty house and how to detect and prevent infestations will help you protect your home from these persistent pests.
