In Eastern Europe, kidney bean leaves are spread on the floor of a bedbug-infested room to “trap” bedbugs. The leaves are destroyed then after.
Natural ways to get rid of bedbugs. The mechanism behind this practice can be attributed to the microscopic hooked hairs (i.e., trichomes) on the bean leaf surfaces that impale the feet of bedbugs. When impaled by the trichomes, the bedbugs are unable to free themselves despite their struggle.
Expose surfaces and hidden areas to the heat emitted by the sun to kill also the eggs. Sustained steam treatment can also eliminate bedbugs at all stages, but this method can sometimes be ineffective since the bugs are good hiders – and may not be suitable for all furnishings.
