Bed Bug Casings: An Overview

Bed bugs, including young bed bugs and the adult bed bugs, are notorious for their ability to infest our homes, causing discomfort and distress. These tiny, blood-sucking pests leave behind a trail of evidence, such as bed bug casings, as they grow and develop. It’s important to know what bed bugs prefer in order to prevent and control their infestations.

Bed bug casings, also known as bed bug shells, are the exoskeletons that these insects shed throughout their lifecycle. When you find these casings, it’s a sign that you may be dealing with a bed bug infestation.

The Purpose of Bed Bug Casings

Bed bugs, including adult bed bugs, shed their skin for a few reasons, primarily to facilitate growth and maturation, enabling their bodies to expand and acquire new characteristics. This shedding process also helps bed bugs rid themselves of parasites that might have hitched a ride on their exoskeletons.

Discovering a first or second instar bed bug casing is crucial, as it implies a high probability of the bed bug emerging from an existing infestation. Understanding the rate of bed bug molting is vital for detecting and treating an infestation, as it helps identify live bed bugs and their growth stages.

Indicators of a Bed Bug Infestation

While finding bed bug casings can suggest a potential infestation, it’s not a definitive indicator of an active infestation with adult bed bugs or nymphs. If you do come across bed bug casings, it’s essential to thoroughly inspect your home for other signs, such as:

  • live bugs
  • fecal stains
  • blood spots on bedding
  • bed bug egg casings

The greater the number of shells discovered, including dead bed bugs, baby bed bugs, and those from adult bed bugs shedding their exoskeletons, the more severe the infestation is likely to be. To effectively assess the situation, it’s crucial to find bed bug shells in various stages of their life cycle.

Identifying Bed Bug Casings

Proper identification of bed bug casings is crucial in determining the presence and severity of an infestation. By examining the size, shape, color, and texture of these casings, you can gain insights into the life stage of the bed bug and the extent of the infestation.

Bed bug casings are typically small, oval-shaped, and reddish-brown.

Size and Shape


Bed bug casings vary in size and shape depending on the life stage of the bed bug, including the presence of bed bug eggs and bed bug nymphs. They can range from 1/16 inch to 3/8 inches in length. These casings are typically oval in form and measure approximately 1.5-2mm, depending on the nymph stage.

Finding casings of various sizes can indicate the presence of bed bugs in different growth stages, giving you an idea of the progression of the infestation.

Color and Texture


Bed bug casings are generally reddish-brown in color, firm, and rigid, with a texture that is known to be crunchy when crushed. However, they can also display a lighter hue, ranging from translucent to whitish, white, or tan, with a papery texture.

Common Misidentifications

It’s not uncommon for people to mistake other objects for bed bug casings. Some frequent misidentifications include carpet beetle skins, spider egg sacs, and other insect casings.

Additionally, lint, food crumbs, or human skin cells are often mistaken for bed bug casings.

Locating Bed Bug Casings


Bed bug casings can be found in various locations throughout your home, including bedrooms, furniture, and personal belongings. Knowing where to look for these casings can help you catch an infestation early and take the necessary steps to eliminate it.

Inspecting your home regularly for bed bug casings is an important part of preventing an infected home.

Bedroom Areas

  • Mattress seams, folds, and crevices of mattresses or box springs
  • Near the piping, seams, and tags of the mattress and box spring
  • Cracks on the bed frame and headboard

Additionally, it’s crucial to inspect other areas in the bedroom, such as nightstands, wall paintings, drawers, cabinets, and the space underneath the bed for bed bug casings.

Furniture and Personal Belongings

Aside from bedroom areas, bed bug casings can also be found in upholstered furniture, wooden furniture crevices, and personal belongings. Be sure to inspect these items carefully and thoroughly to ensure you’re not overlooking any hidden casings.

Handling Bed Bug Casings


Handling bed bug casings involves safe disposal and thorough cleaning to prevent future infestations. It’s crucial to remove these casings and eliminate any remaining bed bugs to ensure your home is free from these pesky pests.

To do this, you should start by vacuuming the area to remove any visible casings.

Safe Disposal

To dispose of bed bug casings safely, place them in a sealed plastic bag and then place the sealed bag in an outdoor trash bin located away from the home. This ensures that any remaining bed bugs or eggs are removed from your living space and won’t cause a re-infestation.

Taking these steps will help protect your home from a bed bug infestation and keep your home healthy.

Cleaning and Sanitizing

After disposing of bed bug casings, it’s essential to clean and sanitize affected areas to remove any remaining bed bugs and eggs. Use a vacuum cleaner with a crevice tool to effectively remove casings, and then clean the area with a stiff brush to scrub away any remaining bed bugs or eggs.

Additionally, you can use a steam cleaner or boiling water to kill any remaining bed bugs and their eggs.

Preventing Future Infestations


Preventing future bed bug infestations is essential to maintaining a comfortable and healthy living environment. By conducting routine inspections and taking proactive measures, you can significantly reduce the chances of another infestation occurring in your home.

Regularly inspect your home for signs of bed bugs, such as dark spots on mattresses.

Inspect your home for signs of bed bug casings and other indicators of an infestation, and take action as soon as possible if any evidence is found.

Proactive Measures

  • Using bed bug-proof mattress and box spring covers
