Per the Riptide 5.0% Pyrethrin ULV product label, to get the mix rate for a 125-gallon tank you should multiply the system tank size in gallons by fluid ounces of concentrate per gallon of water (1.16) and that'll give you, 145 oz of solution needed to use in a 125 gallon.
If staining or a spill of the Riptide 5.0% Pyrethrin ULV had occurred on the concrete, we would recommend using an absorbent product such as sand, kitty litter, or similar material to soak up as much of the residue from the porous surface of the concrete as you can. If a stain remains, you may need to try a pressure washer or a concrete stain remover from a hardware store.
Riptide 5.0% will only kill insects while it is wet. This is a contact kill-only product so once it is dry, it is completely safe, and completely gone leaving no residuals behind.
