What Other Bugs Look Like Bed Bugs?

It's late at night, and as you crawl into bed, you spot a small, reddish-brown bug darting across your sheets. Or perhaps you spot what you think is casings or droppings.

Whatever the case, you feel your heart sink—it’s got to be a bed bug infestation, right? Not so fast.

Although bed bugs are a common household pest, they're often mistaken for other bugs that look strikingly similar. Misidentifying these insects could mean unnecessary stress, wasted time, and the wrong approach to solving the issue.

So what other bugs look like bed bugs?

Identifying bed bugs based on appearance alone is tricky, even for pest control experts. These tiny pests share features with other common insects, like cockroach nymphs, bat bugs, and spider beetles. But while they may look alike, their habits, habitats, and elimination strategies differ.

Let’s get into what makes bed bugs unique, which pests mimic their appearance, and how you can benefit from calling in the pros (hint, that's us!) to put your worries to rest.

What Makes Bed Bugs Unique?

Before we dig into their lookalikes, let's take a quick look at what makes bed bugs stand out.

Bed bugs are tiny, flat, and oval-shaped insects, usually reddish-brown in color. Adults are roughly the size of an apple seed, though they swell slightly and turn more reddish after feeding.

Despite what their name suggests, these pests don’t limit themselves to beds. They hide along cracks in furniture, baseboards, and even electrical outlets, emerging at night to feed on blood—yours, to be specific.

What’s more, bed bugs are sneaky. They're flat enough to squeeze into the tiniest crevices and clever enough to avoid detection for weeks or even months. That’s one reason they're so feared—they're tough to spot until the bites start to show up or you notice their droppings, shed skins, or eggs.

That said, the presence of a bed bug lookalike doesn’t mean you’re safe, either. While not all imitators bite, many bring their own sets of issues—like damage to furniture or contamination of food supplies. Identifying the culprit is critical to effectively solving your pest problem.

Now that you know how to identify bed bugs, let’s talk about some common look-alikes.

1. Cockroach Nymphs

Cockroach nymphs are one of the most common insects mistaken for bed bugs. When newly hatched, they’re small, reddish-brown, and flat—eerily similar to an adult bed bug.

The difference? Cockroach nymphs have longer antennae and a more cylindrical shape. You’ll also find them hanging around kitchens and bathrooms rather than beds and couches since they’re drawn to crumbs, food residue, and water, not blood.

2. Bat Bugs

Bat bugs could win an imitation contest against bed bugs, making them notoriously challenging to differentiate. The two species look almost exactly identical.

Native to caves and attics, bat bugs primarily feed on bats, but if their preferred hosts move out—or die—they’ll settle for humans. The fine hairs longer on their thorax can help distinguish them from bed bugs, but you’d need a magnifying glass (or one of our pros) to spot the difference.

3. Spider Beetles

Spider beetles are tiny, round insects with a shiny, reddish-brown appearance. Sound familiar? They’re often mistaken for young bed bugs.

However, spider beetles have longer legs, a humped back, and no taste for blood. Instead, they’re pantry pests, typically found in food storage areas such as cabinets and pantries. If you’ve discovered them near your bed, chances are they’re in search of crumbs, not you.

4. Carpet Beetle Larvae

Carpet beetle larvae get their name thanks to their preferred hiding spots—textiles like rugs, carpeting, and upholstery. These bugs are often mistaken for bed bugs because of their size and color.

Unlike bed bugs, their diet mainly includes natural fibers and debris. While they won’t bite, carpet beetle hairs can cause skin irritation that is often confused with bed bug bites.

5. Fleas

Fleas may occasionally mistake people for their regular hosts—pets like cats and dogs—leading to itchy red bites. But how do you tell them apart from bed bugs?

Fleas are much smaller and more agile jumpers. If you spot these pests latched onto your pet or hopping from one place to another, you're likely dealing with fleas, not bed bugs.

Why Correct Identification Matters

Spotting a bug can be alarming, especially if you're not sure what you're dealing with. Misidentifying the pest can lead to wasted efforts and even make the issue worse.

Case in point? Using DIY bed bug treatments on cockroach nymphs won’t solve your infestation. Instead, understanding the specific pest allows for targeted treatment and long-term elimination.
