A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.
Cimex lectularius, or the common bed bug, is a species of Cimicidae. Its primary hosts are humans, and it is one of the world's major "nuisance pests." Although bed bugs can be infected with at least 28 human pathogens, no studies have found that the insects are capable of transmitting any of these to humans. [1]
Bed bugs spend much of their time in dark, hidden locations like mattress seams, or cracks in a wall. [2] Treatment is directed towards the symptoms. [2] Eliminating bed bugs from the home is often difficult, partly because bed bugs can survive up to approximately 300 days without feeding. [6] [8] Repeated treatments of a home may be required. [2]
Green offers this helpful analogy: “Think of bed bugs like germs. We carry germs around; they need people to survive, but sometimes we leave germs in places, and other people pick them up and ...
Once the bed bugs had acclimated to their new home, the container was lifted; they had four days to explore the room. In some runs, the room also contained a block of dry ice to simulate a ...
The bed bug, Cimex lectularius, is an external parasite of humans. It lives in bedding and is mainly active at night, feeding on human blood, generally without being noticed. [93] [94] Bed bugs mate by traumatic insemination; the male pierces the female's abdomen and injects his sperm into a secondary genital structure, the spermalege.
Wash all the laundry and dry on high heat (at least 125 degrees Fahrenheit) to kill bugs. Put anything that cannot be washed in the freezer (at least 0 degrees Fahrenheit) for at least 72 hours.
The Cimicidae are a family of small parasitic bugs that feed exclusively on the blood of warm-blooded animals. They are called cimicids or, loosely, bed bugs, though the latter term properly refers to the most well-known member of the family, Cimex lectularius, the common bed bug, and its tropical relation Cimex hemipterus.
