Bed Bugs Bite
Bed bugs are most likely to bite when they have easy access to a host at rest—usually during the night while people are sleeping. These bugs are nocturnal and drawn to the carbon dioxide and body heat humans emit, which helps them locate exposed skin. Bites typically occur in the following situations:
When Staying in Infested Locations: Infestations in hotels, dorms, shelters, or apartment buildings increase bite risk, especially if bed bugs hitchhike on luggage, clothing, or furniture.
After Bringing Home Infested Items: Used furniture, mattresses, or clothing can harbor bed bugs. Once inside, they quickly find sleeping areas and start feeding on people resting nearby.
In Cluttered or Shared Living Environments: Bed bugs thrive where people live in close quarters or where clutter gives them ample hiding spots. The more hiding areas near a bed or couch, the more frequent bites tend to be.
Bed bugs are most likely to bite when a person is stationary and available for an extended period, particularly at night and near their hiding places in mattresses, headboards, or upholstered furniture.
When Do Bed Bugs Bite?
Bed bugs are nocturnal pests, meaning they are most active at night when people are sleeping. They typically bite between midnight and 5 a.m., though they can feed at any time if a host is resting or stationary for long periods.
Their behavior is guided by body heat and the carbon dioxide we exhale. Once they detect a nearby host, bed bugs crawl from their hiding places—such as mattress seams, box springs, furniture cracks, or behind wall outlets—and feed for about 3 to 10 minutes before retreating back to their hiding spots.
While nighttime bites are most common, bed bugs can and will bite during the day if an infestation is heavy or if they’re disturbed from their harborage sites. For instance, people who nap during the day, work night shifts, or spend time resting on infested furniture may still experience daytime bites.
Bed Bug Bites
While bed bug bites are not known to transmit diseases, they can still pose several health, comfort, and psychological risks. The main risks associated with bed bug bites include:
Allergic Reactions: Some individuals experience mild to severe allergic responses to bed bug saliva. Reactions can range from small, itchy red welts to large, swollen hives or even blistering. In rare cases, people may experience systemic allergic responses that require medical attention.
Secondary Infections: Persistent scratching can break the skin, creating open wounds that may become infected with bacteria such as Staphylococcus aureus or Streptococcus pyogenes. Infected bites can result in impetigo, cellulitis, or lymphangitis if not properly cleaned and treated.
Sleep Disturbance: Knowing that bed bugs are active at night often leads to anxiety and insomnia. Repeated bites, itching, and the fear of being bitten can severely disrupt sleep quality and daily functioning.
Emotional and Psychological Stress: Bed bug infestations are notoriously stressful. Many people report anxiety, embarrassment, hypervigilance, or even post-traumatic stress–like symptoms after prolonged exposure to infestations and repeated bites.
Skin Irritation and Scarring: Itchy welts from bed bug bites can linger for several days or weeks. Excessive scratching or delayed healing can lead to hyperpigmentation or minor scarring, especially in individuals with sensitive skin.
Financial and Social Impact: Although indirect, the need to treat infestations, replace infested belongings, and restore living conditions can become financially and emotionally draining—especially if bites persist after failed DIY treatments.
While bed bug bites are not medically dangerous in most cases, the physical discomfort, risk of secondary infection, and psychological toll they cause make prompt and professional control essential.
What To Do About Bed Bug Bites
If you’ve been bitten by bed bugs, it’s important to treat the symptoms properly and address the underlying infestation to prevent further bites. Here’s what you should do:
Clean the Affected Area: Wash the bites gently with soap and warm water to remove any dirt or bacteria. This helps prevent infection and soothes irritation.
Apply a Cold Compress: Use an ice pack or a clean, cold cloth for 10–15 minutes at a time. This reduces swelling, redness, and itching.
Use Anti-Itch or Topical Treatments: Apply over-the-counter hydrocortisone cream, calamine lotion, or an antihistamine cream to relieve itching and inflammation. If itching is severe, an oral antihistamine (like diphenhydramine or cetirizine) can help.
Avoid Scratching: As tempting as it is, scratching can break the skin and lead to infection or scarring. Keeping your nails trimmed and covering bites with a bandage may help resist the urge.
Monitor for Infection: Watch for signs of infection such as increased redness, swelling, pus, or pain. If any of these occur, or if you develop a fever, seek medical attention promptly.
Treat the Infestation: Bed bug bites will continue until the infestation is eliminated. Wash and dry bedding, clothing, and linens on the hottest settings, vacuum regularly, and inspect seams, cracks, and furniture for signs of bed bugs. However, because these pests are notoriously difficult to eradicate, hiring our professional bed bug control services is often the most effective and long-term solution. Contact us to learn more.
Take Steps to Prevent Future Bites: After treatment, use bed bug-proof mattress and pillow encasements, reduce clutter, and inspect any secondhand furniture before bringing it inside.
In most cases, bed bug bites heal within one to two weeks. If you experience an allergic reaction, severe swelling, or ongoing discomfort, consult a healthcare professional for stronger medication or additional treatment.
