Wouldn't the new adults that hatched after 1st application be sterile? However, if there is an IGR in this, wouldn't this 10% population be biting but sterile for 7 months and not lay fertile eggs? Can we just try to avoid being bit by them and slowly vaccum them up to avoid a second spray?
Heavy infestations may require retreatment after 14 days with Precor 2000 Plus Premise Spray. It is rare that flea infestations are eliminated with just one application unless it is a very light infestation. Generally it take a few applications. Vacuuming is very important when treating for fleas. For best results, vacuum thoroughly before spraying and discard or empty the vacuum bag in outside trash. Continue vacuuming frequently to help remove flea eggs and flea debris. You can monitor the treated areas for activity and decide to reapply or not in 2 weeks.
