Presentation
Bed bugs live in any articles of furniture, clothing, or bedding, so they or their eggs may be present in used furniture or clothing. [medicinenet.com]
Finding no insects identified as bed bugs does not mean that bed bugs are not present. It can mean that the inspection was inadequate, or that bed bugs are present but so few in number that the inspector missed them. [dph.illinois.gov]
If you are seeing these spots it may be an indicator of bed bug activity or a potential for Bed Bugs being present. As well discarded nymph casings and dark blackish fecal matter may also be present. [winnipeg.ca]
Countless adults and nymphs present (Adults walking on walls, clustered in cracks on walls, stained curtains, etc. [colonialpest.com]
When only a few bed bugs are present, they live close to human sleeping areas; when numerous, they can be found in many rooms of the house. A characteristic “bed bug odor” is frequently present in a home infested with bed bugs. Image 1. [ento.psu.edu]
Entire Body System
- Swelling
They can be very itchy and there may be painful swelling. A severe allergic reaction (anaphylaxis) is also possible but rare. How you can treat bedbug bites Bedbug bites usually clear up on their own in a week or so. [nhs.uk]
Sensitivity to bed bug bites varies; some people may show only a small red bump, while bites in others can cause swelling, inflammation or rash. Bed bugs are not known to transmit diseases to humans. [msdh.ms.gov]
Once they eat they turn dark red and swell in size. Nymphs are shaped like adults but are yellowish white in color. Bed bug eggs are white (about 1 mm long) and pear shaped. The eggs have a sticky coating and are deposited in cracks and crevices. [novascotia.ca]
If you scratch the bite, you may cause a secondary infection that can lead to swelling and bleeding. [healthline.com]
Small, flat, or raised bumps on the skin are the most common sign; redness, swelling, and itching commonly occur. Raised bumps on the skin Blisters on the skin A spreading red rash There are no symptoms and signs associated with bed bug bites. [medicinenet.com]
- Fever
The consequence may be severe (rheumatic fever, nephritis, endocarditis, etc.) Chronic headache may be caused simply by a constitutional disposition or be the result of a brain tumor or a brain aneurysm. [en.wikipedia.org]
Anyone can get pruritus but certain groups of people are more susceptible to the condition, including: People with seasonal allergies, hay fever, asthma, and eczema People with diabetes People with HIV/AIDS and various types of cancer, especially those [webmd.com]
