There are 20 pictures of bed bugs below showing their different sizes and shapes, from egg to nymph to fully-fed adult. Many are displayed next to objects to show you how small they are and how difficult it can be to find them.
Pictures of Bed Bugs, Big and Small
Bed bugs are small, reddish-brown, oval-shaped, about the size of an apple seed, and their bodies are usually between 4-5 mm long and 1.5-3 mm wide. Bed bugs have six legs and use their two antennae to sense the heat and carbon dioxide emitted by their human hosts. Bed bugs are reddish-brown and can become reddish after a blood meal.
Here are some key characteristics of bed bugs’ appearance:
- Flat, oval-shaped body.
- Rusty-brown color.
- Six legs and two antennae.
- Wingless, although they can hitch a ride on a bat and enter your home that way.
- Adults are about the size of an apple seed (4-5 mm long and 1.5-3 mm wide). Nymphs (young bed bugs) are smaller and lighter in color, and translucent before their first feeding.
What Color Are Bed Bugs?
Bed bugs are typically reddish-brown, although they can be lighter in color if they haven’t fed recently. After feeding, their bodies become more swollen and darker in color. Bed bug eggs are white and about the size of a pinhead, while nymphs are translucent and become darker as they feed on blood. As shown in the picture above, the eggs are sticky and will stick to a surface – the best way to remove them is with a fine tooth comb.
How Big Are Bed Bugs?
As mentioned earlier, an apple seed and an adult bed bug are about the same size, with a length of 4-5 mm and a width of 1.5-3 mm. However, nymphs are much smaller and range from 1.5 mm to 4.5 mm. Our page on the seven stages of a bed bug’s life cycle has a fantastic photo of an infested mattress with each stage clearly shown.
What Does a Bed Bug Look Like Up Close?
Bed bugs have a flat, oval-shaped body and six legs when viewed up close. They also have two antennae that are shorter than their bodies. In addition, bed bugs’ bodies are covered in tiny hairs, and they have a beak-like mouthpart that they use to pierce the skin and feed on blood.
Bed bugs’ bodies are segmented, giving them a striped appearance and appearing flat after a few days of not feeding, but once they feed, their bodies are oval-shaped from being engorged with blood.
What does a bed bug egg look like?
Bed bug eggs are tiny, about 1 millimeter in size, and have a pearl-white color. They can be challenging to spot due to their small size and are often found in clusters or hidden in dark, protected areas.
Do Bed Bugs Have Wings?
No, bed bugs do not have wings. They are wingless insects, which means they cannot fly. However, they can move quickly across floors, walls, and ceilings. They can also catch a ride on bats and enter your home that way; these are called Bat Bugs (I know, it gives me the willies also!).
Are Bed Bugs the same as Chinches?
