Fleas tend to leave the sick host under these conditions. Fleas coming from a neighbor's pet. Fleas from this source may collect on your animal and become annoying. The flea lays its eggs while roving about on the animal. The small white egg is not sticky and drops from the host animal into the bedding material, into cracks and crevices, next to the ridges of upholstered furniture, or onto other areas frequented by the animal.
Hatching takes place within a week.
The tiny worm-like larvae feed on animal hair, skin scales, and bits of dried blood in the area where the host animal normally sleeps. This can be in a bed box in the home, in a dog house, or under the front porch. Larvae may also develop wherever eggs have been dropped and a small amount of animal matter is present for food. After about a week, a larva completes development and spins a cocoon in this same location or nearby. The flea pupates inside the cocoon and emerges as the environmental temperature warms.
