Will Onslaught Insecticide or Fastcap kill chiggers faster? Also, since it only kills on contact, how do we obtain long term control? Will this harm pollinators? ...

Answer:

Onslaught Insecticide and Onslaught FastCap will both do a great job for chiggers. Onslaught FastCap would be the faster acting product due to its one of a kind formulation made of Exponent brand synergist, Esfenvalerate, and Prallethrin. This product does not kill on contact. The active ingredients release over time, allowing the pests to pick up the residual and carry it back into wall voids, cracks and crevices, and other spots where they may hide. The product label does state that this product can be highly toxic to bees and other pollinating insects exposed to direct treatment or residues left on blooming crops or weeds. The best way to reduce the chance of the product affecting the bees, butterflies and beneficial insects is to spray later in the day when they are not active and are back in their homes/nests and try to avoid blooms of flowers and plants they would use for pollination.
