I have a house and a shed to treat. How much Onslaught to mix into a 15 gallon Pull Behind Sprayer? Sprayer is pulled by mower. I have a light to medium spider problem. How much to mix with 15 gallons of water?
The mixing ratio for Onslaught FastCap Spider and Scorpion Insecticide is 1 fl oz per gallon of water. You will use 15 fl oz in 15 gallons of water.
