I have been using onslaught for interior and exterior of my house for black widows and scorpions for the past 2yrs and I was told that need to change insecticide every so often so the pest won't get immune to the insecticide.
Onslaught FastCap is a unique insecticide that has an encapsulated pyrethroid plus prallethrin for quick knockdown. Permethrin SFR contains permethrin - a different pyrethroid - and it is not encapsulated. The encapsulation really helps products to last longer in the heat and sunlight in desert environments better than the Permethrin SFR would. Our other most popular insecticides to rotate with Onslaught would be Cyzmic CS or CyKick CS. You could always add 0.25 - 0.5 oz of ExciteR insecticide to either Cyzmic or CyKick for that extra quick knockdown, if desired.
