Can you use Archer IGR, Permethrin SFR, and Deltamethrin together?

Have a bad problem with fleas in yard.

Answer:

You can use Archer IGR + Permethrin and you can use Archer IGR + Deltamethrin but you should not mix all 3 chemicals together because Permethrin and Deltamethrin are from the same class of chemicals and it would be like essentially just doubling the dose of either product. Instead you should mix Permethrin or Deltamethrin + Archer IGR + a pyrethrin such as Exciter. The pyrethrin would give you the really fast knockdown, the deltamethrin/permethrin would give you the long lasting residual and the Archer IGR would help break the breeding cycle.
