I was wondering what to use outside in my yard for fleas and which IGR does a better job outside and which one works longest out of these two 'Martins IGR' or 'Archer IGR'? Are they basically the same product with a different brand name or are they different chemically and work differently?
Either the Archer IGR or the Martin's IGR both contain the same active ingredient, Pyridine 1.3%. They both are photostable up to 14 days outside and are essentially the same product just different manufacturers. You would be able to do more applications with the Archer being in the larger bottle, but either would work the same for fleas outside.
