Introduction

Bed bugs are small, parasitic insects that feed on the blood of humans and animals. They are reddish-brown in color, have a flattened body, and are about the size of an apple seed. Adult bed bugs are about 3/16 of an inch long, while nymphs ( immature bed bugs) can be as small as 1/16 of an inch.

The Size of Bed Bugs

Bed bugs are small insects that feed on the blood of humans and animals. They are brown in color and their bodies are flat. They are about the size of an apple seed.

Nymphs

Nymphs are newborn bed bugs that are translucent and have not yet begun to feed on blood. Nymphs go through 5 instars, or stages, before they reach adulthood. A nymph’s appearance will change after each molt, or shedding of its skin. Nymphs will molt 5 times before they become adults. After the final molt, the nymphs will be rusty brown in color and about the size of an adult bed bug.

Adults

Adult bed bugs are brown to reddish-brown, oval shaped and flattened, with chewing mouthparts. They are about 3/16” long – about the size of an apple seed. Bed bugs do not have wings and their bodies are mostly translucent. Nymphs (immature bed bugs) look similar to adults, but are much smaller and lighter in color.

Conclusion

So, what size are bed bugs? Adult bed bugs are small, flattened insects that grow to only about ¼ of an inch in length. They are reddish-brown in color and have a somewhat oval shape. Immature bed bugs (called nymphs) are even smaller, growing to only about 1/16 of an inch. So, if you’re wondering how big bed bugs can get, the answer is not very big at all!
