Hello: I read your webpage describing strategies for tick control. I keep my grass short, but would like to treat the margins of my mowed area with insecticide, as the ticks seem to migrate inward from the tall grass rather quickly and in large numbers. I have a cabin in Crow Wing County and would like to know which insecticide is best, given the proximity of my yard to a lake and wetlands. Regards, Jon Johnson Merrifield, MN 763-213- 9841
