Avoid tick habitats: Whenever possible, avoid entering
areas that are likely to be infested with ticks, particularly
in spring and summer when nymphal ticks feed. Ticks favor a
moist, shaded environment, especially areas with leaf litter
and low-lying vegetation in wooded, brushy or overgrown grassy
habitat. Both deer and rodent hosts must be abundant to
maintain the enzootic cycle of B. burgdorferi.
Use personal protection measures
If you are going to be in areas that are tick infested, wear
light-colored clothing so that ticks can be spotted more easily and
removed before becoming attached. Wearing long-sleeved shirts and
tucking pants into socks or boot tops may help keep ticks from reaching
your skin. Ticks are usually located close to the ground, so wearing
high top boots may provide additional protection.
The risk of tick attachment can also be reduced by applying
insect repellents containing DEET (n,n-diethyl-m toluamide) to
clothes and exposed skin, and applying permethrin (which kills
ticks on contact) to clothes. DEET can be used safely on
children and adults but should be applied according to
Environmental Protection Agency (EPA) guidelines to reduce the
possibility of toxicity.
After your outing, remove and wash your clothes, shower and inspect your body for ticks.
The transmission of B. burgdorferi (the bacteria that causes Lyme
disease) from an infected tick is unlikely to occur before 36 hours of
tick attachment. For this reason, daily checks for ticks and promptly
removing any attached tick that you find will help prevent infection.
Embedded ticks should be removed using fine-tipped tweezers.
DO NOT use petroleum jelly, a hot match, nail polish, or
other products. Grasp the tick firmly and as closely to the
skin as possible. With a steady motion, pull the tick's body
away from the skin. The tick's mouthparts may remain in the
skin, but do not be alarmed. The bacteria that cause Lyme
disease are contained in the tick's midgut or salivary glands.
Cleanse the area with an antiseptic.
Strategies to reduce tick abundance
The number of ticks in endemic residential areas may be
reduced by removing leaf litter, brush- and wood-piles around
houses and at the edges of yards, and by clearing trees and
brush to admit more sunlight and reduce the amount of suitable
habitat for deer, rodents, and ticks. Tick populations have
also been effectively suppressed through the application of
pesticides to residential properties. Community-based
interventions to reduce deer populations or to kill ticks on
deer and rodents have not been extensively implemented, but
may be effective in reducing the community-wide risk of Lyme
disease.
