Assume that they are, indeed, everywhere. I no longer wear shorts when I stray off the paths or when I garden. Tuck long pants into socks, wear a man’s cotton long-sleeved shirt. When you come back in, inspect every part of your body.
A lyme tick, and especially its larvae are very small. They do not all carry the disease vectors and should be a problem unless they have imbedded themselves on your person and engorged themselves with your blood. Takes about 24 hours; they look like a weird little black fluid-filled sac attached to you (under chin, armpits, pubic area, hair are all possibilities).
Get a kit; ID card, tiny pointed tweezers, alcohol wipes and learn how to remove them so that no feelers remain under your skin. Save the tick in alcohol. Keep an eye out for bull’s eye rash.
