Bedbugs

Microbiology

Review

C. lectularius and C. hemipterus are reddish- brown, flat, wingless ovals (4–7 mm). They eat blood (think Twilight) and can live for 12 months without feeding and up to 1.5–2 years in colder environments.

Epidemiologic Risks

Bedbugs fear light (hmm. Twilight again) and are usually active at night. They hide in bedclothes, mattresses, springs, bed frames, cracks, crevices, and wallpaper. They emit an easily recognized, offensive odor that is like a stink bug. Bedbug salvia is anesthetic. Beware of free furniture on the street. It is being given away for a reason.

Syndromes

An itchy erythematous maculopapule, 5 mm to 2 cm in diameter, with a central hemorrhagic crust or vesicle. That describes most rashes. It is occasionally urticarial.

45 different pathogens have been suggested as spread by bedbugs; none have been definitely proven to have used Bed Bugs as a vector,. However, Vancouver, BC Bed Bugs have been found to carry MRSA and VRE.

Treatment

Bedbug eradication is a difficult: Insecticide resistance is increasing and garlic doesn't work. You need to remove all bed linens and washing at a temperature of 60°C, checking and dismantling all furniture to access all bedbug hiding places, to identify and destroy eggs and vacuuming everything. There are dogs trained to find them.

Notes

They have been cultured and not only listen to opera and watch ballet, but also carry MRSA and VRE (PubMed). Which is worse?
