A late start to spring means deer and wood ticks are emerging later than usual. But the Minnesota Department of Health expects normal numbers of the pests this year.
MNN reports Epidemiologist Dave Neitzel saying as soon as the ground temperature reaches about 50 degrees they are out and feeding.
Neitzel says the heavy snow helped insulate the ticks during the harsh winter.
He recommends applying a repellant with the chemical permethrin to clothing which lasts several weeks.
