Where Do Bed Bugs Come From? Understanding Their Origins and How They Spread

If you’ve ever had a bed bug problem, your first question might have been, “Where did they come from?” It’s a fair question and one that causes a lot of frustration. Bed bugs seem to appear out of nowhere and make themselves right at home. At Thermopest, we’ve helped countless people deal with bed bugs, and the truth is, they come from places you might not expect.

Bed bugs have been around for thousands of years, and despite our best efforts, they’ve made a strong comeback in recent decades. Whether you’ve just discovered a few suspicious bites or you’re dealing with a full-on infestation, let’s dive into where bed bugs come from and, more importantly, how to keep them out.

The History of Bed Bugs

Believe it or not, bed bugs aren’t new. They’ve been pestering humans for thousands of years, with records of infestations dating back to ancient Egypt. Back then, they thrived in caves and warm environments, feasting on both humans and animals. Fast forward to modern times, and bed bugs have evolved into masters of hiding and hitchhiking.

The resurgence of bed bugs in recent years is largely due to global travel and urbanisation. More people are travelling, and bed bugs are going along for the ride. Add in the fact that these pests have grown resistant to certain pesticides, and it’s no surprise that they’re becoming more of a problem.

Common Sources of Bed Bug Infestations

So, where do bed bugs come from? Here are the most common ways they sneak into your home:

Travel and Accommodation

Bed bugs love to hang out in places with lots of human traffic—hotels, motels, hostels, and even Airbnb. They’re experts at hopping onto your luggage, clothes, or shoes without you noticing. You could check into a perfectly clean hotel and still bring home a few unwanted guests.

Whether you’re staying in a budget hotel or a five-star resort, it’s always smart to inspect the bed and surrounding areas for signs of bed bugs before settling in. If you’ve travelled recently, it’s a good idea to inspect your luggage and wash your clothes on a high heat setting as soon as you get home.

Second-Hand Furniture and Clothing

Who doesn’t love a good bargain? Picking up second-hand furniture, clothes, or even a mattress can be tempting, but it’s one of the most common ways bed bugs find their way into homes. While that vintage sofa might look fabulous, it could be hiding a colony of bed bugs in its seams.

Before bringing any second-hand items into your home, always inspect them thoroughly. Look for tiny black spots (which could be bed bug faeces), shed skins, or the bugs themselves. Giving items a good clean before use is also a smart precaution.

Public Spaces

Bed bugs don’t just stay in beds. They can be found in all sorts of public spaces—cinemas, buses, trains, and even offices. Anywhere people gather, bed bugs might be lurking. They can hitch a ride on your clothing or bag, and you might not even realise it until it’s too late.

Multi-Unit Housing

If you live in an apartment block, dormitory, or any type of shared building, bed bugs can easily move from one flat to another. They’ll crawl through cracks, vents, and electrical outlets, spreading throughout the building without you even realising.

In multi-unit buildings, all residents must work together to keep bed bugs at bay. If one unit has an infestation, it can quickly spread to others. Regular inspections and open communication are key to preventing a building-wide problem.

How Bed Bugs Spread

Once they’ve made their way into your space, bed bugs spread by hitchhiking. They’ll latch onto clothing, bags, and other belongings, and travel from one place to another. Whether it’s your suitcase after a holiday or your gym bag after a quick trip on public transport, bed bugs are great at getting around.

In multi-unit housing, bed bugs don’t need much to spread. They can crawl through the smallest cracks and crevices, moving from one flat to the next. In offices and public spaces, they can hide in chairs, carpets, or anywhere they can find a dark spot, waiting for their next opportunity to spread.

Why Bed Bugs Are Hard to Detect

One of the reasons bed bugs are such a pain is that they’re experts at staying hidden. They’re small (about the size of an apple seed) and prefer to hide in cracks, seams, and crevices. Most people don’t notice they have a problem until the infestation has grown.

Where Bed Bugs Hide

Bed bugs typically hide in mattresses, bed frames, headboards, and furniture seams. But they can also sneak into electrical outlets, cracks in the walls, and behind picture frames. They come out at night to feed, which makes it even harder to catch them in the act.

Delayed Signs

It can take a few weeks for you to realise there’s an infestation. Bed bugs bite, but not everyone reacts to their bites right away. It’s often the small black faecal spots or blood stains on your bedding that first alert people to the problem.

How to Prevent Bed Bug Infestations

Prevention is always better than cure, especially when it comes to bed bugs. Here are some practical steps to keep these pests from setting up shop in your home:

• Inspect Luggage and Clothing After Travel
  After staying in a hotel or hostel, inspect your luggage and clothing carefully. Wash your clothes in the highest heat setting, and if possible, leave your suitcase outside until it’s been thoroughly checked and cleaned.
• Check Second-Hand Items Carefully
  Before bringing any second-hand furniture or clothing into your home, inspect it thoroughly. Look in the seams, cracks, and hidden areas where bed bugs could be lurking. If you’re unsure, give it a good clean or steam treatment before use.
• Regularly Inspect Your Home
  It’s a good idea to regularly check your mattress, bed frame, and other furniture for signs of bed bugs. Early detection can save you a lot of trouble down the line. Bed bug-proof mattress covers and bed bug monitors are also a great investment for peace of mind.

What to Do If You Suspect Bed Bugs

If you’ve spotted bites, blood stains on your sheets, or those tell-tale black spots, here’s what you need to do:

• Recognise the Signs
  Look for red, itchy bites (often in clusters or lines), small blood stains on bedding, black faecal spots, or shed skins. These are clear signs that bed bugs have made their way into your home.
• Quarantine Affected Areas
  If you think bed bugs are in your bed or furniture, isolate the area. Remove bedding and clothes carefully, sealing them in plastic bags until they can be washed on a high-heat cycle.
• Call in the Professionals
  Getting rid of bed bugs on your own can be tough. They hide in places you’d never expect, and they multiply quickly. At Thermopest, we specialise in thorough bed bug inspections and treatments that ensure every last bug is eliminated.
