Tick population is out of control here in MA...though if this dry spell continues, it will have a big effect. Ticks thrive in a pretty narrow band of high humidity.
Contrary to what some may think...the significant snow cover this winter, provided excellent insulation/protection for immature ticks and lots of moiture/humidity as it melted.
Permethrin is definitely the way to go...and clothing soak is very effective. Generally speaking, 2 types are available...spray bottle and liquid "soak".
The soak offers very good protection through at least several washes and the spray is great to hit boots and pant cuffs for some added insurance.
Gaiters are a HUGE help...especially when treated also. No need for the mack daddy top of the line gortex type...cheap stretchy ones marketed to trail runners are fine as long as they close/cover the gap between your boots and pant leg.
