Baby fleas back 2 weeks after

I applied Precor mixed correctly in a pump sprayer and applied throughout my home. It's been about 2 weeks since the application and I've seen 2 very small fleas today. The pets are all on a prescription flea tablet which is administered monthly, and before we applied Precor we've bombed twice, and applied Ortho Home Defense Max 3x throughout our entire home and treated our yard with a spray treatment. We've been battling fleas for 3 months. Why after two weeks are we seeing a new batch after applying an IGR?


Flea elimination indoors can take 2-8 weeks depending on the level of infestation. Indoor flea control will require you to use a mix of insecticides and also mechanical control methods. We recommend using at least 2 products to control fleas; an insecticide such as Onslaught Insecticide and an insect growth regulator such as Precor IGR. You can usually find an insecticide and an insect growth regulator together in a aerosol flea product. After 14 days, you should reapply the aerosol or liquid products to the carpets, rugs and pet's resting areas to control any newly emerging immature fleas. Severely infested areas may require a 3rd or even a 4th treatment in 14 day intervals.
