Common Causes of Bed Bug Infestations: How They Start and How to Prevent Them

No one wants bed bugs in their home, yet infestations happen more often than you might think. Bed bugs are sneaky little pests, and once theyโ€™re in, they can be a nightmare to get rid of. At Thermopest, weโ€™ve seen the stress these pests cause and, more importantly, weโ€™ve helped countless homes and businesses get back to normal.

But the best way to deal with bed bugs? Avoid bringing them into your home in the first place. In this guide, weโ€™ll break down the common causes of bed bug infestations and how you can prevent these uninvited guests from moving in.

Understanding Bed Bug Habits and How They Spread

Bed bugs are surprisingly resourceful for such tiny creatures. Knowing a bit about their behaviour can help you avoid crossing paths with them.

  • Bed Bug Behaviour

Bed bugs love dark, tight spaces. Theyโ€™ll hide in cracks, seams, and crevices during the day, only coming out at night to feed on blood. Itโ€™s not just your bed theyโ€™ll settle inโ€”bed bugs can be found in sofas, chairs, and even cracks in walls.

And hereโ€™s the kicker: Bed bugs can survive for months without feeding. So, even if youโ€™ve been away for a while, bed bugs can patiently wait for your return.

  • How Bed Bugs Travel

Bed bugs donโ€™t have wings, but theyโ€™re expert hitchhikers. They latch onto your belongingsโ€”luggage, clothing, furnitureโ€”and travel from one place to another. This makes it easy for them to spread without you even realising it.

Common Causes of Bed Bug Infestations

So, how do bed bugs find their way into your home? Letโ€™s look at the most common ways these pests spread.

1. Travel and Accommodation

If youโ€™ve ever stayed in a hotel, hostel, or Airbnb, thereโ€™s always a risk of bringing bed bugs home with you. Even in the cleanest of hotels, bed bugs can hide in mattresses and furniture, ready to hitch a ride in your luggage. It only takes one undetected bed bug to create an infestation back home.

2. Public Transport and Shared Spaces

Bed bugs arenโ€™t just found in homesโ€”they can be anywhere people gather. Public transport like buses, trains, and even taxis can be a hotbed for these pests. They can crawl onto your clothing or bags as you sit in a theatre, cinema, or even an office chair. Before you know it, youโ€™ve brought a new โ€œfriendโ€ home.

3. Second-Hand Furniture and Clothes

We all love a good bargain, but second-hand items can be a big risk. That lovely vintage chair you picked up? It could be hiding a family of bed bugs in the seams or cracks. The same goes for second-hand clothes that might carry bed bug eggs in the fabric.

4. Visitors and House Guests

Even the most well-meaning guest could bring bed bugs into your home without realising it. If a visitor has been staying somewhere infested, they could unknowingly transport bed bugs on their luggage, clothes, or shoes, which can quickly spread into your home.

5. Multi-Unit Buildings

If you live in a flat, dormitory, or hotel, your bed bug risk is higher. Bed bugs can crawl through shared walls, electrical outlets, and even plumbing, making it easy for them to migrate from one unit to another. Once an infestation starts in one part of a building, it can spread quickly if not dealt with.

6. Infested Neighbourhoods

Unfortunately, living in an area with a bed bug problem increases your chances of facing an infestation. Bed bugs can spread between homes, especially in densely populated neighbourhoods, where they move through shared walls or on belongings.

How to Prevent Bed Bug Infestations

Prevention is always better than cure, especially when it comes to bed bugs. Hereโ€™s how you can protect yourself and your home from an infestation.

1. Inspect Travel Luggage and Clothing

After travelling, itโ€™s a good idea to thoroughly check your luggage and clothing before bringing them inside. Bed bugs often hitch a ride on your suitcase or clothes. Wash all your travel clothes in the hottest setting to kill any bugs or eggs that might have come back with you.

2. Check Second-Hand Furniture

If youโ€™re buying second-hand furniture, give it a good inspection. Look for signs of bed bugs, such as small black spots, eggs, or shed skins. Bed bugs love hiding in seams and cracks, so be thorough. Itโ€™s better to spend an extra few minutes checking than to deal with an infestation later.

3. Use Bed Bug-Proof Mattress Covers

Investing in a bed bug-proof mattress cover is a simple but effective way to keep these pests out of your bed. These covers zip around your mattress, preventing bed bugs from getting in or out. Even if you unknowingly bring bed bugs into your home, a mattress cover will stop them from settling into your bed.

4. Declutter to Reduce Hiding Spots

Bed bugs love clutter because it gives them more places to hide. Keeping your home tidy and organised reduces the number of hiding spots for bed bugs. It also makes it easier to spot any signs of an infestation early.

5. Regular Home Inspections

Make it a habit to inspect your home regularly for signs of bed bugs, especially if youโ€™ve recently travelled or bought second-hand items. Check your mattress, bed frame, and any upholstered furniture. Early detection can save you from a full-blown infestation.

What to Do If You Suspect a Bed Bug Infestation

Sometimes, despite your best efforts, bed bugs still manage to find their way in. If you suspect bed bugs, hereโ€™s what you should do.

1. Recognise the Signs

Common signs of bed bugs include small red bites (often in clusters or lines), black spots on your mattress or furniture (bed bug faeces), or finding shed skins. If you notice any of these, itโ€™s time to act.

2. Quarantine Affected Areas

If you think bed bugs have made their way into your bed or furniture, try to contain the infestation by quarantining the affected area. Strip your bed of all sheets and wash them on a hot setting. Avoid moving infested furniture to other parts of your home, as this could spread the problem.

3. Call a Professional

Bed bugs are notoriously difficult to eliminate without professional help. If you think your home has been invaded by bed bugs, donโ€™t waste time with DIY methods that might not work. At Thermopest, we offer expert pest control services to get rid of bed bugs and ensure they donโ€™t return.

Final Prevention Tips

Bed bug infestations are no fun, but by being vigilant and taking preventive measures, you can protect your home from these pests. Keep an eye out for signs, inspect items before bringing them inside, and take action at the first hint of bed bugs. And remember, if you do find yourself dealing with an infestation, Thermopest is here to help.

With the right approach, you can stop bed bugs from taking over your homeโ€”so you can sleep easy at night, knowing your bed is bug-free.
