More simply, a nymph is a bed bug that hasn’t fully matured into adulthood. It’s helpful to know what immature bed bugs look like since they can leave behind the most evidence.
Pictures of nymphs
As you can see in the pictures, nymphs look like smaller versions of adult bed bugs and have the same flat, seed-shaped bodies.
Nymphs grow about half a millimeter with each feeding and subsequent morph. In the picture you can see how much a fully engorged nymph grows after hatching. Look at the spent egg casing next to the bug’s blood-filled body.
You can also spot bed bug eggs from hatched nymphs. These eggs are white and measure approximately one millimeter or about the size of a grain of rice. They are typically tucked into the piping of your mattress as well as other bed bug hiding spots.
Nymphs grow after each feeding, leaving skins in clusters. Under proper conditions, each morph can take about a week. As adults, these bed bugs will take in blood meals every seven to 10 days (all the while mating until your home is completely overrun).
While a nymph won’t advance to the next stage without a blood meal, this doesn’t mean it will die. Nymphs can last for months without feeding, while adult bed bugs can go more than a year. Along with their expert hiding skills, this is why they are so difficult to kill.
