However you call them baby bed bugs, those little bed bugs are literally called nymphs. Before explaining these bugs or nymphs, you must learn about the life stages of bed bugs.

Bed bugs have 3 life stages: Egg, nymph, and adult. As you can see easily, they are eggs first. After hatching the eggs, bed bugs that hatched are called nymphs and when they grow big enough, they’re called adults Bed Bugs.

Identifying Baby Bed Bugs


These early-stage bed bugs are small and translucent, with a whitish-yellow color. They are roughly the size of a pinhead when they first hatch and can grow up to 4-5mm in length as they reach adulthood. At each stage of development, their color darkens and their bodies become more elongated.


Like adult bed bugs, these bed bugs are nocturnal and prefer to feed on their hosts at night. They are also very good at hiding, and they can squeeze into tight spaces that are difficult to reach. They are attracted to the carbon dioxide that humans exhale and the warmth of our bodies, which helps them locate their hosts.

Signs of a Baby Bed Bug Infestation

If you suspect that you have a baby bed bug infestation in your home, there are several signs to look out for.


Tiny bed bug bites are similar to adult bed bug bites and typically appear as small, red, itchy welts on the skin. However, because these tiny bed bugs are smaller than adults, their bites may be more difficult to see.

Blood Spots

When small bed bugs feed, they can leave behind small blood spots on sheets and other bedding. These blood spots are typically about the size of a pinhead and may be red or brown in color.

Fecal Matter

As mini bed bugs digest their blood meals, they will excrete fecal matter that can appear as dark spots or smears on bedding, furniture, and walls. These spots are often referred to as “bed bug poop” and may be mistaken for other types of stains.
