What Attracts Bed Bugs


Have you ever wondered why bed bugs seem to infest certain places and not others? These tiny, nocturnal pests can cause significant distress and discomfort, and understanding what attracts them is key to preventing infestations. In this article, we will delve into the world of bed bugs, exploring their behavior and habits, as well as the factors that make certain environments more enticing to them. By the end, you’ll have a clearer understanding of what attracts bed bugs and how to protect yourself from these unwelcome intruders.

Understanding Bed Bugs

  1. What are Bed Bugs?

Bed bugs, scientifically known as Cimex lectularius, are small, wingless insects that belong to the family Cimicidae. They are blood-feeding parasites, primarily feeding on humans, but also other warm-blooded animals. These pests have been around for centuries and have adapted to live in close proximity to humans.

  1. Physical Characteristics

Bed bugs have distinct physical characteristics that set them apart from other insects. They are reddish-brown in color, with flat, oval-shaped bodies. As adults, they measure about 4 to 5 millimeters in length, roughly the size of an apple seed. Their bodies are segmented, and they have six legs and two antennae.

  1. Behavior and Habits

Bed bugs are primarily active at night, preferring to feed on their hosts while they sleep. They are attracted to warmth, carbon dioxide, and body odor. These pests are expert hitchhikers and can easily travel from one location to another by latching onto luggage, clothing, or furniture.

Factors that Attract Bed Bugs

  1. Warmth and Heat

Bed bugs are attracted to warmth and heat. They seek out environments with temperatures ranging from 70 to 80 degrees Fahrenheit (21 to 27 degrees Celsius). This is why they are commonly found in beds, as our body heat provides the ideal conditions for their survival and reproduction.

  1. Carbon Dioxide

Just like mosquitoes, bed bugs are drawn to the carbon dioxide we exhale. When we breathe, we release carbon dioxide into the air, creating a trail that bed bugs can detect. This is one of the primary ways they locate their hosts.

  1. Body Odor and Perspiration

Our body odor and perspiration can also attract bed bugs. These pests are attracted to the chemicals emitted by our sweat glands, making areas with higher sweat production more appealing to them. Regular personal hygiene can help reduce the chances of attracting bed bugs.

  1. Clutter and Hiding Places

Bed bugs prefer cluttered environments with plenty of hiding places. They seek out cracks, crevices, and dark corners to hide during the day, emerging at night to feed. Excessive clutter provides them with numerous hiding spots, making it easier for them to establish and expand their colonies.

  1. Dirty and Untidy Environments

Dirty and untidy environments create favorable conditions for bed bugs. They thrive in places with abundant food sources, such as shed skin cells, hair, and other organic matter. Neglected spaces with poor cleanliness are more likely to harbor bed bug infestations.

  1. Travel and Movement

Bed bugs are excellent hitchhikers and can easily latch onto luggage, clothing, or furniture during travel. They are commonly found in hotels, motels, and public transportation, making it important to be cautious when staying in unfamiliar places or using shared transportation.

Common Bed Bug Hotspots

  1. Hotels and Lodging

Hotels and lodging establishments are common bed bug hotspots due to the high turnover of guests. Bed bugs can easily hitch a ride on luggage or clothing and infest rooms, spreading from one guest to another. Checking hotel rooms for signs of bed bugs before settling in is a wise practice.

  1. Public Transportation

Buses, trains, and airplanes can serve as vehicles for bed bug transportation. These pests can hide in the upholstery, cracks, and crevices of seats, making public transportation a potential source of bed bug infestations. Taking precautions such as using luggage encasements and avoiding direct contact with seating surfaces can help minimize the risk.

  1. Shared Living Spaces

Dormitories, shared apartments, and communal living spaces are susceptible to bed bug infestations. With numerous people living in close proximity, the chances of an infestation occurring and spreading are higher. Regular inspections and maintaining cleanliness can help prevent bed bug problems in shared living spaces.

Preventing Bed Bug Infestations

  1. Regular Cleaning and Vacuuming

Regular cleaning and vacuuming can help eliminate bed bugs or their eggs before an infestation takes hold. Pay close attention to cracks, crevices, and other hiding places where bed bugs are likely to reside.

  1. Sealing Cracks and Openings

Sealing cracks and openings in walls, baseboards, and furniture can reduce the number of entry points for bed bugs. By minimizing their access to your living space, you can significantly lower the risk of an infestation.

  1. Washing and Drying Bedding

Washing bedding, including sheets, pillowcases, and mattress covers, in hot water can kill any bed bugs present. Follow this up by drying them on high heat to ensure the complete eradication of these pests.

  1. Using Mattress Encasements

Using mattress encasements can help protect your bed from bed bug infestations. These specially designed covers create a barrier that prevents bed bugs from infesting or escaping from the mattress, thus providing an additional layer of protection.

  1. Being Cautious While Traveling

When traveling, be cautious and proactive to prevent bringing bed bugs home with you. Inspect hotel rooms for signs of bed bugs, keep your luggage elevated and away from the bed, and wash your clothes in hot water immediately upon returning home.

Detecting and Treating Bed Bugs

  1. Signs of Bed Bug Infestation

It’s important to be able to recognize the signs of a bed bug infestation. These include the presence of small, reddish-brown stains on bedding or furniture, tiny dark spots (bed bug excrement), shed bed bug skins, and a distinct sweet, musty odor in the affected area.

  1. DIY Bed Bug Treatment

While DIY bed bug treatment methods may help in minor infestations, they are often insufficient for more severe cases. Vacuuming, steam cleaning, and using bed bug sprays or powders can provide temporary relief, but professional assistance is usually required for effective eradication.

  1. Professional Extermination Services

Professional extermination services have the expertise and tools necessary to effectively eliminate bed bugs. They employ a combination of methods such as heat treatments, insecticide applications, and targeted inspections to ensure complete eradication and prevention of reinfestation.


Understanding what attracts bed bugs is crucial for preventing infestations and protecting your home and personal space. Factors such as warmth, carbon dioxide, body odor, clutter, and unclean environments make certain places more attractive to these pests. By taking proactive measures, such as regular cleaning, sealing cracks, and being cautious while traveling, you can significantly reduce the likelihood of encountering bed bugs. If you do find yourself facing a bed bug infestation, it is advisable to seek professional assistance for effective and long-lasting eradication.
