What does the youth portion of the flea not cover?

The youth portion of the flea typically does not cover adult flea life stages, such as pupae or larvae, which can remain in the environment and continue the infestation cycle. It may also not address other pests or health issues related to pets, such as ticks or parasites. Additionally, the youth portion might exclude certain treatments or preventative measures for different species or ages of animals. Always consult product labels for specific coverage details.
