Scabies vs. Bedbugs: What Are the Differences

Rarely, immunocompromised people may have herpes zoster without a typical rash. In these cases, samples from your rash or blisters can be scraped and sent to a laboratory to confirm the diagnosis.

It is important to note that these symptoms by themselves are not an indication that one is infested with scabies. To be sure that one is infested with scabies, one has to eliminate the possibility that the skin condition one is suffering from is not acne or mosquito bites. If it is an attack of scabies, then the dead give- away will be the persistent itch that accompanies the rash. You can also notice burrows on the skin sometimes.

Humans typically don’t know when either type of Demodex mite is living on their skin, except when Demodex folliculorum mites are present in high densities on a person with an immune system imbalance and are transferred between hosts through contact involving hair, eyebrows, and/or sebaceous glands on the nose.

Crusted (Norwegian) scabies primarily affects elderly people and those with a weakened immune system, disability or neurological condition. It’s more contagious than typical scabies because it spreads via person-to-person contact and also through the shedding of the skin crusts. When crusts fall off, the mites inside can survive for up to a week, which gives them time to find another host.

Mange is the name of a category of skin conditions caused by microscopic parasites called mites in humans and animals. While most commonly associated with dogs, humans can also contract mange, which typically results in scabies or demodicosis.

It’s possible to visually spot bedbugs, but the bites are often the first sign of an infestation. You might also see tiny red or black specks of blood or excrement on your bedding or smell a sweet, musty odor.
You can tell you have scabies because you develop a rash that tends to itch only at night.

Treating crusted scabies is more challenging, and treatment may last for several weeks or longer if necessary. People with crusted scabies may be prescribed both a scabicide and another mite killer called benzyl benzoate, along with a keratolytic cream, which helps reduce crusting of the skin and allows for better absorption of permethrin or benzyl benzoate.

Treatment for these two pests is very different. Once you get rid of a scabies infestation, you don’t have to worry about treating surfaces and areas in your home since the mites can’t live long off of human skin. Bedbugs, however, can hide and keep reproducing as long as they have access to blood.

Demodex folliculorum is one of two types of Demodex mites (Demodex brevis is the other) that live in or near hair follicles of mammals. Both species are found on humans, but Demodex folliculorum is the type of mite responsible for a human skin condition known as demodicosis.

Machine wash bedding, clothing, and towels in hot water and dry in a hot dryer (dry-cleaning will also decontaminate articles). If you can’t wash or dry clean an item, keep it away from contact with skin for at least 72 hours.
