How much Archer IGR should be used per gallon when treating my property with a backpack mister?

Also, how often should Archer be applied? I plan on using the Bifen IT, Exciter and Archer all together but am wondering if I will have to use all three chemicals every time I spray (Bifen IT every 28 days)

Answer:

Archer IGR would be mixed at .5 to 1 oz per gallon of water.  You can mix Bifen IT, Archer, and Exciter together in the same mix everytime you spray.  Both Archer and Bifen can be used every 14 days outdoors for active infestations.  Exciter is a quick contact kill only so can be used more often if needed.
