What is Flea Larvae? - Larva is one of the three immature stages of a flea’s four stage lifecycle (egg, larva, pupae and adult). The Larva itself goes through further phases from the time of hatching out of the egg to reaching the pupa step. Once the flea is at its pupating stage, it develops to an adult within a cocoon. The adult is then encouraged out of the pupal casing when conditions are right (normally via vibrations of a nearby host, combined with carbon dioxide, humidity and heat) and can jump on to and begin feeding on a host within minutes.
The eggs which female adult fleas lay hatch into Larvae. Female fleas can lay up to 950 eggs in their lifetime and the larvae size is very small. It is important to understand the lifecycle process so that any prevention and control can be applied thoroughly to your home and yard. After all, prevention is a lot less painstaking than having to deal with an establishing infestation.
What does Flea Larvae look like? - Larvae look like little worms, which can grow up to a quarter of an inch in length, have no legs and have the ability to crawl. They begin with an off-white color which develops into a more yellow/brown color through the lifecycle. It is common for the larvae to be found in areas where house pets live (if the host of the fleas are house pets), although they have the ability to crawl up to twenty feet away to find their perfect environment. They like a dark and warm area to hide and develop. Temperatures of around 85 degrees Fahrenheit and a high humidity are most favourable for them to progress through this part of their lifecycle. When searching for larvae, look in shaded areas, where they purposely avoid light.
