If you want to rid the apartment of fleas first spray with a flea bomb or mixture
for indoor pest control. If you do not spray with something like Precor then you will have a fresh batch of fleas in just weeks after spraying. Precor makes the flea egg incapable of hatching therefore the cycle is broken. Use an indoor pesticide then use Precor or mix them together for just one spray. If you use
Precor every 2 months year around you will not have fleas. Precor is not a poison so it is safe to use in an occupied space.
