What Size Are Bed Bugs?

Bed bugs are small, parasitic insects that feed on the blood of warm-blooded animals, including humans. They are reddish-brown in color and have flattened bodies that allow them to hide easily in cracks and crevices. Bed bugs are typically around 4-5 millimeters in length, which is about the size of an apple seed. However, they can range in size from 1-9 millimeters depending on their age and feeding status.

Nymphs, which are immature bed bugs, are smaller than adults and can be as small as 1 millimeter in length. They are also lighter in color than adults and become darker as they mature. Bed bugs go through five nymphal stages before reaching adulthood, and each stage requires a blood meal before they can molt and progress to the next stage.

Adult bed bugs are typically around 4-5 millimeters in length and are reddish-brown in color. They have oval-shaped bodies that are flattened dorsoventrally, which means they are flatter from top to bottom than from side to side. This allows them to hide easily in tight spaces, such as between mattress seams or in cracks in furniture.

Female bed bugs are slightly larger than male bed bugs and can be up to 9 millimeters in length when fully engorged with blood. After feeding, bed bugs become swollen and elongated, and their bodies turn a darker red color. They can hold up to seven times their own weight in blood, which allows them to survive for long periods of time without feeding.

Bed bugs are nocturnal insects and are most active at night when their hosts are sleeping. They feed by piercing the skin of their host with their sharp, beak-like mouthparts and sucking up blood. Bed bug bites can cause itching, redness, and swelling, and they can also lead to allergic reactions in some people.

Bed bugs can be a nuisance and can make it difficult to sleep at night. They can also spread diseases, such as Chagas disease and hepatitis B. If you think you may have a bed bug infestation, it is important to contact a pest control professional immediately.
