Where Do Bed Bugs Come From? Causes, Signs & Prevention

Evolving since the era of dinosaurs, and still being almost absolutely harmless to human beings, is a wonder in itself. Bed bugs are small, wingless, flat, six-legged insects that are 1-7mm in length and are almost clear to reddish-brown in colour. These bugs often travel a lot to find your place and infest your home. However, where do bed bugs come from? This is one question that can easily prevent and remove these bugs from ever entering again.

These bed bugs were never rare. Anytime you go into a public space, you might carry a few things back home. Moreover, because they are extremely small, they can hide and burrow into tiny, narrow spaces such as cracks, electrical outlets, and furniture joints. Today, public transportation, hotel rooms, airplanes, retail stores, and movie theaters all provide a perfect opportunity for the bed bug population to move from place to place.

Now, if you want to stay away from those bugs and termites and prevent your sleeping mattress from being attacked by a bunch of creepy bugs. Contact Rice Termite for effective and affordable bed bug pest control services in and around Maryland.

What are Bed Bugs?

Bed bugs are small insects that look very similar to ticks. They can look golden and clear in colour, but as they get older, their colour becomes darker. These bugs tend to stay within 8-10 feet of their host, which they feed off of. You can identify their presence if your bed linens show reddish or brownish fecal spots or alongside the adjacent walls.

If you think there is a presence of bed bugs, a registered or licensed pest control operator like Rice’s Termite & Pest Control should be notified so your home can be inspected, the insects can be identified, and an extermination plan can be formed.

What Attracts Bed Bugs?

Before we understand what keeps a bed bug holding on to your bed sheets, we need to understand where do bed bugs come from. According to some historians, the bed bug’s origin is linked to the Middle East and has survived a long history of evolution.

These insects are blood seekers which initially fed on bats and other warm-blooded animals before shifting to people.These are not cockroaches or ants searching for bits of leftover food. The only reason why these bed bugs are motivated towards anything is their biological instincts which tell them that there is a living, breathing host around:

Carbon Dioxide: They are capable of detecting the carbon dioxide we breathe out from up to a distance of three feet.

Body Temperature: Using heat sensors, they detect our skin; however, they cannot do so beyond short distances.

It is believed that filth attracts these bugs, but this is just a misconception because being clean does not deter them. These bugs are found in luxury hotels as well.

Why do Beg Bugs Exist?

Bed bugs have survived for centuries due to incredible biological adaptations. But today, they live to drink blood and reproduce. With 115 million years of evolution, the bodies of bed bugs have developed significant resistance to pyrethroid insecticides, making over-the-counter sprays largely ineffective.

While it can take almost 6 times their weight in blood during one feeding session, people rarely notice a bite until later. These bites inject saliva into their host’s body during feeding, which can later produce allergic reactions on the skin. These swellings may not develop until a day or more after feeding, but may cause irritation when scratched.

How Bed Bugs Are Formed and Reproduce

Bed bugs are identical to other blood-sucking species like the conenose or bat bugs. However, a bed bug will have shorter hair than the diameter of the eye, but the swallow bugs will have longer hair.

Now, to know how bed bugs reproduce? Bed bugs practice a unique mating process called traumatic insemination. The male stabs his reproductive organ through the female’s body wall into a specialized organ called the Organ of Berlese. The female’s body must then heal from this wound. Consequently, mated females often leave the group to avoid further “abuse.” This biological drive to escape repeated mating is the scientific reason a single female will move to a new room or apartment, inadvertently spreading the infestation

Female bed bugs are known to lay 200 to 500 tiny white eggs during their lifetimes. Usually, two to five eggs per day, on rough surfaces such as wood or paper near their hosts, sleeping places, resting places, or both. A gluelike material covers the eggs, which hatch in about 10 to 15 days at room temperature.

The lifecycle of these eggs to turn into an adult requires anywhere from five weeks to four months and includes five nymphal stages. To continue to mate and produce eggs, both males and females must feed at least once every 14 days.

How to Prevent Bed Bugs From Entering Your Home

Have you heard about a research carried out in Canada in 2025 indicated that there is a link between bed bugs infestation and mental conditions like anxiety and depression? There are no documented cases of bed bug bites causing infectious diseases but some individuals react severely to bed bug bites and develop itchy and red spots.

There was a belief before that bed bugs could stay alive for one whole year without food. It has been proved now through scientific findings that the lifespan of a bed bug without eating anything is just two months if the temperature exceeds 70 degree Fahrenheit.

The only way to keep these bugs away from your home is by cleaning your house regularly and vacuuming your bed mattress. Bed bugs can easily come into any person’s house by travelling through movies, public transportation services, or by checking into a hotel room.

Prevent these bugs from entering by:

  • Cleaning your house and bedroom area regularly.
  • Removing clutter around your living area reduces the number of places these bugs can hide.
  • Wash your clothes and inspect your luggage immediately after returning from a trip.
  • Inspect used furniture before bringing it to your home.
  • Never bring discarded bed frames, mattresses, box springs, or upholstered furniture into your home.

Now, if you find yourself surrounded by these bed bugs, you can follow the tips mentioned below to remove them completely.

  • Contact a pest control company for bed bug identification.
  • Use your vacuum’s nozzle to capture bed bugs and their eggs. After cleaning, immediately place all the sucked-in content into a sealed plastic bag and throw it away in an outdoor garbage can.
  • Wash your linens in hot water and place them in a hot dryer for at least 20 minutes.
  • Cover your mattress, box spring, and pillows with a certified bed bug cover encasement.
  • Never use pesticides on your own to treat bed bugs. Bed bombs, or total release foggers, are not effective in controlling bed bugs. While controlling an infestation is difficult, improper use of pesticides can incur serious health risks as well.

When to Call a Pest Control Service for Bed Bugs

Bed bugs are creatures that bite humans and feed on their blood. While these bugs are not life-threatening, they are difficult for a person to eradicate on their own. A professional and reputable pest control  service uses an integrated pest management (IPM) approach, combining several tactics like;

  • Whole-Room Heat Treatments
  • Canine Detection
  • Chemical Expertise

Call a professional like us if you see live bugs in multiple rooms, blood smears on sheets, or a “breakfast, lunch, and dinner” bite pattern. This pattern occurs because a bug may probe the skin several times to find a capillary where blood flows rapidly.

Conclusion

Bed bugs have existed since time immemorial, and are very specialized travelers attracted by our breath and body heat. Bed bugs have a reproductive process where one female can settle an entire building, and are experts at survival in the dry environments of our homes.

But still, they are controllable. Through proper heating of clothing, inspection of hotel rooms before accommodation, and use of Integrated Pest Management if required, you can create your bug-free haven.

FAQs

  • What attracts bed bugs the most?

The primary attraction for bed bugs is the Carbon dioxide released by our body as well as the heat. They rely on odors called kairomones which lead to skin where they can have a blood meal. 

  • How are bed bugs formed inside a home?

Bed Bugs come into a home strictly as hitchhikers on infested objects like luggage, second-hand furniture, or clothing. Once inside, they grow through 5 nymphal stages, requiring blood to molt and develop.

  • Why do bed bugs exist if homes are clean?

Bed bugs are parasites that feed on blood only. They are not attracted to trash or unsanitary conditions as an infestation has been observed in the cleanest of homes if a host is available. 

  • Why do bed bugs come into bedrooms?

Bed bugs prefer places where their food remains stationary. Since bed bugs are nocturnal and most active between midnight and 5:00 AM, the bedroom serves best for feeding on hosts during their sleep

  • Where do bed bugs come from after traveling?

They are often picked up in high-turnover locations like hotels, dormitories, or public transport. They crawl from infested surfaces into the seams of bags or the folds of clothing.

  • Do I need a pest control service for bed bugs?

Yes. Due to their ability to hide in tiny cracks and their widespread resistance to common insecticides, DIY efforts often fail. Professionals use IPM strategies like heat and specialized tools for total eradication.

  • Can Rice Termite help remove bed bugs permanently?

Yes. Rice Termite uses professional techniques that can achieve total removal. However, permanent prevention depends on your ongoing habits, such as inspecting for new hitchhikers after traveling.
