American and Italian scientists have hypothesized why bed bugs that feed on human blood and live in the bedroom do not remain directly on the host, like lice.
It is all the fault of the substances secreted by human skin – the so-called triglycerides, which are the main component of the surface fatty lipid film, Gazeta.ru reports with reference to an article in Scientific Reports.
In the course of experiments, which, together with colleagues, conducted by Sudip Gaira and Zachary DeVries from the Department of Entomology at the University of Kentucky, it turned out that although the smells of human skin, carbon dioxide and heat attract hungry bugs, the secretions and fats on the very skin of people are still not pleasant to bedbugs. allow them to linger for a long time on their masters.
Bed bugs (Cimex lectularius) are blood-sucking insects that live in close proximity to humans. They have spread throughout the world and are among the most ineradicable parasites, inhabiting homes, hotels, sheds, pet cages and poultry houses.
