The insect book [microform] : a popular account of the bees, wasps, ants, grasshoppers, flies and other North American insects exclusive of the butterflies, moths and beetles, with full life histories, tables and bibliographies. Insectes; Insects. -^^â - 9/^^ltfi â ' ^^'*^,- ^f^^^ - â -^^~ - - V*t«i Fleas the writer's office in Washington, showed that the larva casts its first skin in from three to seven days, and its second skin in from three to four days. From seven to fourteen days after hatching, they began to spin a delicate silken cocoon, which, when com- pleted, was almost transparent, except where it was covered with dust particles. In the cocoon the pupa, as shown in the accompanying figure, was formed and the insect remained in the pupal condition for four days. Thus an entire generation may he developed in about a fortnight, and since the adult female lays many eggs, it is not surprising that persons having cats or dogs about the house will frequently (and especially where the houses are closed during the summer, and the floors left unswept) lind their domiciles overrun with thousands of these active, biting creatures. The remedies consist in a free use of fresh pyrethrum powder, in spraying the floors and floor coverings with benzine or in thoroughly washing the floors with hot water and soap. On pet animals pyrethrum powder should be freely used. '94.
