Socks. I am terrified to wear them now. They would jump on my socks and live there while biting my ankles to death. I had a pair of slippers with fur on them... Those because infested with hundreds. I threw those out. With no pets in the house... I wonder how long they can live. I vacuum and mop daily. I also do the lamp and a bowl of dawn water mix trap.
The funny thing about socks is that the fleas seem to stay in them, so the one time I had fleas on the carpet in my room, I only had visible flea bites on my ankles, where the socks were.
Honestly if you manage to vacuum all the eggs fast enough, you will never really know because you would have solved the problem before they become a problem.
