What Do Bed Bugs Look Like?

Bed bugs are tiny, reddish-brown in color. Their bodies have three segments with six legs and two antennae. A single bed bug can easily be seen by the naked eye. It could be said that, at a distance, a bed bug looks like an apple seed. 

You’ll know it’s a bed bug if it has:

  • Reddish-brown color
  • Flat ovular body that becomes engorged after a meal
  • 5 mm length (about the size of an apple seed)
  • Tiny white oblong eggs

How big is a bed bug?

Bed bugs are very small.

Mature bed bugs reach 5 mm long. Unfed, their thorax is rounded. After feeding blood from a host, they appear larger; their thorax look longer, more cylindrical, and brighter red in color. Adult bed bugs can be spotted by the naked eye easily, but they tend to be hard to spot because they hide out of view, waiting until you go to sleep.

The Life Cycle of Bed Bugs

Bed bugs lay their eggs in hidden places like under the mattress, inside furniture, baseboards, floorboards, and cracks in the wall. Their eggs are tiny, white, and oblong. Eggs hatch into nymphs that look like smaller versions of the adults that they will soon become. Each blood meal they eat allows them to shed their exoskeleton and grow larger. They do this several times before maturing into an adult bed bug.

How to identify bed bugs on Long Island

Bed bugs can easily be mistaken for other pests, so it’s useful to learn the different ways to identify them. They are quite small, so using a magnifying glass can be helpful. If you’re not sure, we recommend hiring a professional bed bug exterminator.

It’s important to know as soon as possible whether you’re dealing with bed bugs or not. Otherwise, an infestation can get out of hand and quickly spread to other places.
