What Causes Bed Bugs: Top 6 Reasons Revealed (2022 Updated)

Maybe you have heard the phrase “don’t let the bed bugs bite” many times, thinking it’s just an idiom to wish someone a good night’s sleep until you wake up with bed bug bites. 

Dealing with bed bugs is a nuisance, but what causes bed bugs in the first place? Read here to find out. 

Top 6 Causes of Bed Bugs

Top 6 Causes of Bed Bugs

1. Traveling

One of the first causes of bed bugs is traveling. We hate to break it to you, but you can bring home bed bugs when you travel. 

They do not have wings to fly, but they can crawl, and since bed bugs are not picky, they can travel by hiding in your luggage, backpacks, car seats, wheelchairs, toys, or sleeping bags. 

The prime spots where you can pick up bed bugs are the beds or furniture where you place your things when traveling, whether on domestic, cruise ships, or international trips. Learn how to move without taking bed bugs with you

2. Used Furniture

Used Furniture

Most people love to buy used furniture but do you know that bed bug infestations commonly start there?  

Bed bugs hide on furniture, and sometimes, people unintentionally sell their used furniture without checking for signs of bed bugs. It’s truly tempting to buy things at low prices so you’ll grab the chance; sadly, it comes with a package-bed bug infestation. 

Before buying second-hand upholstered furniture, check for any sign of bed bugs by using a flashlight on edges, seams, and cracks. Also, check for tiny bloodstains, and bed bug excrement as part of disease control. 

3. Home Rentals

Bed bug infestation in home rentals and apartment complexes is never unusual. Bed bugs are fond of home rentals because they can go from one unit to another- hitchhiking from people and things. 

You can pick up bed bugs during moving, especially if the apartment complexes are already infested with bed bugs. In addition, once a single apartment picks up used or recycled furniture with bed bugs, expect that the whole apartment complex can experience bed bug infestation. 

4. Hotels & Motels

Hotels & Motels

Here’s the reality: when you are on vacation, you rarely think that a hotel or motel has bed bugs because you are excited to lay on those soft and comfortable mattresses. But what if we tell you that bed bugs can also infest hotels and motels? 

Guests come and go, so there’s a big possibility that they can be a carrier of bed bugs. Hotels and motels do not clean their rooms thoroughly, especially with many guests. 

With this, never leave your things on the floor of hotels and motels because bed bugs can travel easily between floors and rooms.

Before settling down, check mattresses, cabinets, and the electric outlet for any signs of bed bug infestation. Find out how hotels deal with bed bugs here

5. School Infestation

Bed bugs can transfer easily from clothing and other things, so you might bring them home when you come home from school. Bed bugs love living on furniture like shelves, upholstered surfaces, and even electrical outlets. Since your kids spend several hours sitting, they can be their blood meal – and go home with them, too! 

Some schools don’t deep clean and vacuum regularly, so when we place our belongings on tables and floors, bed bugs can crawl on them. More on bed bugs at school here

6. Workplace Infestation

Workplace Infestation

Bed bugs live in any public area with a human host, and another common place is the workplace. 

If your workplace has an existing infestation, imagine how many bed bugs live there and how high the chance you will take home one with you. If your workplace has bed bugs, it would be best to contact pest control experts and have the infestation dealt with promptly.

FAQs 

Do bed bugs live on people?

No, bed bugs do not live on people. They see humans as hosts, attracted to them, but they don’t live there. After feeding, they go back to their hiding places to rest, mate and lay eggs. 

In addition, they hide in places where they cannot be seen easily, and they don’t wander, unlike other pests. They mostly live on mattresses, box springs, bed frames, wall cracks, and other bedroom appliances.

Do bed bugs prefer cities or rural areas?

Bed bugs do not prefer a particular location to live and multiply because they make a home anywhere there are humans or animals. However, since most people move to cities, most bugs can be found there. 

In addition, a city is a busy place, so people don’t have too much time to clean up or even notice an infestation unless itchy bites are bothering them. Remember that humans are their hosts, and the closer they live with them, the easier for them to multiply and spread to other places. 

Does a dirty house cause bed bugs?

A dirty house does not cause bed bugs, but that does not mean that your dirty home can be bug-free. Bugs do not care if your home is clean or dirty because they only need a warm host, exposed skin, and plenty of hiding spots. 

However, cleanliness has been a great factor in bed bug infestations because their population does not decrease. If you vacuum regularly, wash clothes with hot water, launder bedding in high heat, and seal cracks, bed bugs may eventually die.

When people are sleeping at night, the carbon dioxide we release surrounds our heads, and then the bugs will start to poke our skin because our blood is their food. Here’s how you can prevent bed bug bites while sleeping.   

Are bed bugs hard to get rid of?

Yes, bed bugs are hard to get rid of but possible. Removing bugs takes time and effort, especially a massive infestation.
