Wearing boots and long pants and ducktaping the pant legs to the boot will stop ticks from crawling up your legs in the woods and on trails, it's the most effective method I've found in 25 years of surveying. After wrapping the tape well applying a healthy dose of heavy deet repellents like Deep Woods Off on boots, pants and spraying your clothes around your waist will stop most ticks and chiggers from getting anywhere besides your head/neck. I hate putting anything but the 7% deet, aloe/skintastik type repellents on my skin anymore, the higher deet sprays make my arms/face/neck burn and turn red in minutes in the sun and sweating and I've had to wash even light spraying off immediately several times. Also if your only out for 2-4 hrs you can shower when you get home and scrub well all over w a washcloth/soap and that will remove most ticks and chiggers before they dig in, scrub well around legs ankles and feet to get the chiggers off, after 3-5 hrs chiggers can get into your skin and can't be scrubbed off. If you use the 7% on boots, clothing, etc you need to re apply it about every 2 hrs or you'll get some bites.
