Insects That Look Like Bed Bugs
It’s common to panic when spotting any tiny crawling pest indoors, fearing it might be a bed bug. Yet, several insects closely resemble bed bugs, leading to frequent misidentifications. Below are some pests often confused with bed bugs:
- Carpet Beetles: Although carpet beetles resemble bed bugs in shape, they come in various colors and have very short antennae. Their larvae look quite different, fuzzy, and caterpillar-like. They don’t bite humans, but the tiny hairs on their larvae can cause skin irritation, sometimes mistaken for bed bug bites. Carpet beetles are typically found in carpets or upholstered furniture, where they feed on natural fibers such as wool.
- Booklice: Booklice have elongated bodies, larger heads, and bent antennae that set them apart from bed bugs. They’re usually found in damp areas, feeding on mold and mildew rather than blood from hosts.
- Fleas: Fleas are small, reddish-brown, and look slightly like bed bugs but tend to be longer, flatter, and smaller. Flea bites generally show up in random clusters on the body and become noticeable within an hour, unlike bed bug bites, which often appear in linear or zigzag patterns and may take days to surface.
- Ticks: At first glance, ticks’ small, flat, and wingless bodies can look similar to bed bugs. They also feed on human blood and cause itchy bite marks. However, ticks have eight legs, unlike bed bugs’ six. Moreover, ticks often stay attached to their hosts for hours or days instead of lingering on beds, furniture, or clothing.

How to Tell if You Have Bed Bugs or Carpet Beetles
At a quick glance, carpet beetles and bed bugs can be mistaken for one another due to their tiny, oval shapes. But beyond that, they have distinct differences. Here’s what sets them apart:
- Color: Carpet beetles come in a range of colors, whereas bed bugs are consistently reddish-brown.
- Size: Carpet beetles are generally smaller than bed bugs. Bed bugs have a flat shape and are about the size and shape of an apple seed.
- Antennae: Carpet beetles possess short antennae, unlike bed bugs.
- Eyes: Bed bug eyes are visible when viewed closely, but the eyes of carpet beetles are difficult to see.
- Larvae: Bed bug larvae resemble longer, thinner worms, while carpet beetle larvae look like tiny, fuzzy caterpillars.
How Big are Bed Bugs?
An adult bed bug grows up to about 5 mm long, comparable to an apple seed. Their size generally falls between ¼ and 3/16 of an inch. This size changes based on feeding status; after a blood meal, they become longer, more cylindrical, and redder. Even though they hide well, adult bed bugs can be seen with the naked eye, offering some reassurance for detection.
Bed Bug Life Cycle
The bed bug life cycle begins with eggs, which hatch into five nymph stages before reaching adulthood. Females deposit their eggs in places like mattresses, furniture, cracks in walls, baseboards, and floorboards. These eggs are small, white, oblong, and roughly 1 mm long.
Young bed bugs, called nymphs, look like smaller versions of adults. After feeding, they molt multiple times by shedding their exoskeleton until they become mature adults.
Identifying Bed Bugs in St. Louis
