Yes, after pupating, cocooned adult fleas can enter into a quiescent state for up to 5 months. Most will emerge right away, but a few may enter this sleep-like state. They’ll remain quiescent until they detect heat and pressure on the cocoon, which is indicative of a host resting on the cocoon. Vacuuming is useful for triggering the pre-emerge adults to emerge, as it simulates these host cues.
