Can You See Bed Bugs? How to Spot the Signs of an Infestation

“Can you actually see bed bugs?” This is a question we hear often at Thermopest, and the short answer is yes—most of the time. But seeing them isn’t always as simple as you’d hope. Bed bugs are small, sneaky, and masters at hiding in places you’d never think to look.

So, how can you tell if you’ve got bed bugs lurking in your home? Let’s walk through what these pests look like, where to find them, and the signs that you should keep an eye out for.

What Do Bed Bugs Look Like?

Bed bugs are tiny, but they’re not invisible. If you know what you’re looking for, spotting them isn’t too difficult—if they’re out in the open, that is.

Adult Bed Bugs

An adult bed bug is roughly the size of an apple seed—about 4 to 5 millimetres long. They have a flat, oval shape and are reddish-brown in colour. After feeding, they swell up and darken, which makes them easier to spot.

Eggs and Nymphs

Bed bug eggs, on the other hand, are much harder to see. They’re tiny—only about 1 millimetre long—and white, blending into most surfaces. Nymphs (young bed bugs) are smaller than adults and lighter in colour, almost translucent, which makes spotting them a bit of a challenge.

Can You Spot Bed Bugs with the Naked Eye?

In theory, yes. You can see adult bed bugs with the naked eye. But here’s the catch—they’re incredibly good at hiding. During the day, they’ll tuck themselves away in cracks, seams, and crevices, making it difficult to catch them out and about. They don’t usually come out until you’re fast asleep, which is when they do their feeding.

That said, if you’ve noticed bite marks, small blood stains on your sheets, or a strange musty smell, you may already have a bed bug problem. These pests often stay hidden during the day, but they leave behind plenty of evidence that something is amiss.

Other Signs of Bed Bug Infestations

While bed bugs themselves may be tricky to spot, they leave behind plenty of clues. Here are the signs to watch out for:

• Bites on Skin
  Bed bug bites are often the first sign people notice. They usually appear as red, itchy welts and tend to show up in clusters or lines. You’ll most commonly find them on skin that’s exposed while you sleep, like your arms, legs, and neck.
• Blood Spots on Bedding
  Small blood stains on your sheets or pillowcases could be from bed bugs feeding. As they feed on your blood, they can accidentally get squashed, leaving tiny red spots behind.
• Faecal Stains
  Bed bugs leave faecal matter behind wherever they hide. These stains appear as small black or brown spots on your mattress, sheets, or furniture. You might even spot them on walls or bed frames near their hiding spots.
• Shed Skins
  As bed bugs grow, they shed their skins. These skins are pale yellow and often found near the cracks or seams where bed bugs hide.
• Musty Odour
  In large infestations, bed bugs can give off a strange, musty smell. It’s caused by the pheromones they release, and it’s a sign you’ve got a serious problem on your hands.

How to Inspect Your Home for Bed Bugs

If you suspect bed bugs, it’s time to roll up your sleeves and check those common hiding places.

Where to Look

Bed bugs are most commonly found in mattresses, bed frames, headboards, and upholstered furniture. Start by inspecting the seams and edges of your mattress. Look closely at the folds in bedding, between cushions, and in the cracks and joints of wooden furniture.

Tools to Help You Spot Them

A good flashlight and a magnifying glass can be your best friends when looking for bed bugs. You can also place bed bug interceptors under the legs of your bed to catch any that might be crawling around.

What to Do If You See Bed Bugs

If you spot bed bugs or their tell-tale signs, don’t panic. Bed bugs are tough to get rid of on your own, so it’s best to call a professional pest control service like Thermopest. We’ll inspect your home, confirm the infestation, and put together a treatment plan that works for you.

Can Bed Bugs Be Mistaken for Other Pests?

Bed bugs aren’t the only small pests you might come across in your home. It’s easy to confuse them with other insects like fleas, carpet beetles, or even small spiders. So, how do you tell the difference?

Common Look-Alikes

• Fleas: Fleas are smaller and jump, while bed bugs don’t. If you’ve noticed your pets scratching a lot, fleas might be to blame.
• Carpet Beetles: These beetles are rounder and more colourful than bed bugs, often mistaken for them due to their small size.
• Ticks: Ticks are commonly found on pets and are bigger than bed bugs, with a more pronounced body shape.

Key Differences

Bed bugs are flat and oval-shaped with six legs. They don’t have wings, and they can’t jump like fleas. If you see a bug crawling around your bed but you’re unsure if it’s a bed bug, try capturing it to show a pest control professional.

What to Do If You Suspect Bed Bugs

Think you might have a bed bug problem? Here’s what to do next.

Final Thoughts

So, can you see bed bugs? Yes, but it takes close attention and a little detective work. Knowing their appearance, behaviour, and favourite hiding spots can help you identify them before they take over your space. Remember, early detection is key to preventing a full-blown infestation, so stay vigilant and inspect regularly—especially after travelling or bringing in second-hand furniture.

If you suspect bed bugs but aren’t sure, don’t hesitate to consult a professional for a thorough inspection and expert treatment.
