Onslaught Insecticide can be mixed at 1 oz per gallon of water when treating a heavy flea infestation. We also recommend using an insect growth regulator like NyGuard IGR to stop immature fleas from reaching sexual maturity. Flea treatments do not work overnight. Over the next couple of weeks you should start to see a reduction in the flea population. We recommend a repeat treatment after 14 days to help get rid of any of the stragglers that may have been missed with the first treatment. Severe infestations may require 3 or 4 treatments in 14-day intervals.
