If I remember correctly, I believe NIX has twice the concentration of permethrin than Equate does so I would be very hesitant to use it. If its a liquid spray and not an aerosol, you could dilute it by half and use it the same as the others. I would never use anything with a permethrin concentration above 0.50% around any reptile, and never get any of these solutions directly on the animal in any manner.
