What Do Bed Bugs Smell Like? Insights from Tulsa’s Pest Control Experts


Bed bugs are tiny nocturnal pests notorious for infesting homes and becoming a significant nuisance. Known for their ability to stealthily hide in the nooks and crannies of mattresses and furniture, they emerge at night to feed on human blood. While often identified by itchy bites or visible signs of infestation, bed bugs also have a distinctive odor that may go unnoticed.

In this blog, we’ll explore the common question, “What do bed bugs smell like?” and “Do bed bugs have a smell?”

Understanding the scent of bed bugs can be crucial for identifying infestations, although it is often a challenge without considerable experience. In this blog, we’ll focus on the specific odors associated with these elusive pests as described by seasoned professionals.

What Do Bed Bugs Smell Like?

Distinctive Odors of Bed Bugs

Bed bugs emit a scent that is only easily recognizable with a trained nose. Seasoned pest control professionals describe the smell of bed bugs as a mixture of dandruff and drying blood but with a more acidic yet musty quality. This unique odor is peculiar and usually detectable only by those with years of experience or by specially trained dogs in cases of minor infestations.

Intensity and Detection

Most people might be unable to smell bed bugs, as the odor is subtle and can develop gradually, leading to sensory adaptation. This is similar to how smokers may not realize they carry the smell of smoke. Even detection dogs might be needed for minor infestations, underscoring the subtlety of the scent.

Professionals who have encountered bed bug infestations over the years can sometimes detect their presence by smell in public settings, indicating a severe and long-standing infestation. However, this level of detection expertise is rare and requires extensive experience with these pests.

Scent of Infested Items



Bed bugs infuse distinctive odors into bedding, clothing, and upholstery. These infested items may develop persistent scents that are challenging to eliminate, even after removing the infestation. Often, these odors are subtle and require close inspection to notice. To remove any lingering smells and prevent future infestations, thoroughly clean the affected areas and seek professional treatment. Experienced pest control professionals effectively ensure the removal of all traces of bed bugs and their odors.

Absence of Smell

Interestingly, some people may not detect any odor, even in a significant bed bug infestation. This absence of smell could be attributed to individual variations in the ability to detect scents or to the specific chemical compositions of the bed bugs’ pheromones. More importantly, as professionals noted, the gradual increase in odor coupled with gradual desensitization — similar to ‘nose blindness’ experienced by smokers — can make it difficult for residents to notice the scent over time.

It’s crucial to understand that not smelling bed bugs does not guarantee their absence. The subtlety of their scent makes regular professional inspections essential. These inspections are vital in detecting and addressing bed bug infestations before they worsen.
