Yes, any insect growth regulator may be mixed with Onslaught® FastCap unless prohibited by label.

Onslaught® FastCap was designed to provide multiple forms of control in a single product. Onslaught® FastCap includes prallethrin for a quick knockdown and esfenvalerate, a microencapsulated pyrethroid, to provide residual control. In addition, piperonyl butoxide is included to speed up delivery of the active ingredients to the target insects through the cuticle and combat metabolic insecticide resistance.

The microencapsulated pyrethroid in Onslaught® FastCap is esfenvalerate and this slowly releases active ingredient into the litter over time, working to provide residual control of darkling beetles throughout the length of the entire grow out period.

Onslaught® FastCap is a broad spectrum product that will provide residual control for many insect problems around the farm. It may be used indoors and outdoors.

Onslaught® FastCap cannot be applied to animals. Do not allow animals to come into contact with such areas until the solution has dried.
