Before becoming adult fleas, the larvae transform into pupae within a silk-like cocoon. Pupae remain inside the cocoon for 2 to 4 weeks, sometimes longer. The cocoon is resistant to insecticides and this is why some adult fleas are seen for an extended period, even after the home and pet are treated.
Report Abuse. Fleas generally don't survive past 100 days, even if they live on a host (the animal on which they feed). However, without a host, they have no food source, and may die between 2 and 14 days. The same can't be said for flea eggs and larvae, which do not require a host and can reach high populations. Adult Flea 1. Once an adult flea is deprived of its host, it will basically starve to death. It will generally die between 2 and 14 days.
