Jeffrey from Narragansett, Ri writes,

What is the recommended concentration for general tick control?

The label is VERY vague "Mix 0.4 0.8 fl. oz. of Permethrin SFR in 4 to 25 gallons of water per 1000 square feet". That a range of 1:12.5 or concentration of ~.005% to ~.06%. Yet your web discription says "1 QT yields 20-40 gallons of finished solution". That's a concentration of ~.48% to ~.23%. There's something wrong here. I suspect a .5% solution is probably correct but how much of that should I apply to 1000 sq ft of lawn?

Answer:

Product labels are indeed vague in many cases as this gives the applicator leeway to use different concentrations for different situations. You should use the higher usage rate for heavy infestations, faster knockdowns and longer lasting residuals and lower usage rates for maintenance sprays. You will need to use higher volumes of water to get the product over thick, dense vegetation. If you are treating your lawn for ticks we recommend you use the higher specified usage rate of 0.8 fl oz Permethrin SFR for 1,000 sq ft using whatever volume of water is needed. If you are treating up close to your home you are permitted to use the .5% emulsion (1 2/3 fl. oz. per gallon of water) per 1,000 sq ft as a perimeter treatment.
