Hey there, Does anyone know whether Frontline Plus can contaminate water? The reason I ask this is because I am moving to a plot in April and there are ticks and fleas there (it's really impossible to make sure there is absolutely 100% no ticks and fleas because it is a "wild" structure sort of environment, the previous owner made it like a forest/bushveld setting, trees and all). I know Frontline is effective and I love it, however, there are 2 ponds and a dam on that plot, and there are fish that live there as well. They are not big ponds and are shallow (the water come to just below my knee and I know that my dogs will jump into it and I don't want the fish to be poisoned. Also does the spray on Frontline have the same 3 day rule as the pour on? (No water 3 days before application and 3 days after application). Thanks for your help!
