Been out of the house for 2 weeks, weve been staying with family. Threw out 2 mattresses. Bombed with precour 3 times, sprayed with precour and IGR twice. Went back to access, no living fleas for hours. Could they be hiding? Paranoia leads me to believe its too good to be true?
95-99% of infestations are composed of eggs, larvae, and pupae living in the environment. They are often hidden deep within carpets or other refuges. Many of the immature fleas already in the environment at the time of spraying will be unaffected by the insecticide because it can’t penetrate to the depth of the carpets. So while you may not be seeing any adult fleas currently, it’s likely that you will eventually as these immature stages mature and emerge.
Still, it sounds like you have a mild infestation, which is good news!
Hope this helps!
