Abstract: The present invention provides compositions that may be an aqueous insecticide containing at least one surfactant, such as for instance, sodium lauryl sulfate, at least one preservative, such as for instance, a potassium salt or sodium chloride, a nutrient source, such as for instance a yeast, an organic acid capable of lowering the pH of the aqueous insecticide, such as for instance citric acid, a fragrance, such as for instance geranium oil, and water. The aqueous insecticide may be designed to more efficiently kill and thereby control populations of species of Cimex, such as, for instance, Cimex lectularius.
