Thad from Clayton, Nc writes

Do I need to spray the carpet in the middle of the room? How long does Precor stay in the carpet?

If it needs to be reapplied after 2 weeks, then how long does it stay in the carpet if it is suppose to work for 7 months?

Answer:

You need to spray the entire carpet for flea control. The IGR does last for 7 months to prevent re-infestation but the eggs that were laid prior to the application will keep hatching because they are not sterile and the reapplication is to kill the newly emerged fleas.
