While I used Demize EC and Precor IGR, it knocked fleas down during the minutes Demize was wet on a hardwood floor, the fleas came back within hours full force and vacuuming every day to reduce it is not helping much as each round catches over 25 adult fleas alive, although they seem to be getting smaller in sizes. I understand Premethrin has a residual that will continue to kill these young adult fleas for up to two weeks after a spray as the fleas walk across/in the areas such as cracks i sprayed. Could I simply add Premethrin to the Demize EC/Precor IGR mixture or does Premethrin have such as fast knockdown there is no point to Demize being used with it during a single spray of 1000sq ft?
Mixing Demize EC + Precor + Permethrin SFR would be a great idea. You will have the quick knockdown of Demize EC, plus residual power of Permethrin SFR, Plus residual IGR power. Be sure to follow the label instructions for mixing.
