How do you determine when fleas have been completely eradicated from your home and pets?

To determine if fleas have been completely eradicated from your home and pets, you should continue treatment for at least 3-4 weeks after you no longer see any fleas. This ensures that any remaining eggs or larvae are also eliminated. Regularly vacuuming, washing bedding, and using flea treatments on pets can help prevent reinfestation. If you continue to see fleas after this period, you may need to consult a professional pest control service for further assistance.
