Combating ticks in nature is difficult. Chemicals could have dramatic consequences for the environment. To reduce the incidence of ticks it can help to remove tall grass, shrubs and bushes. On some islands with major tick problems it can help to remove deer which are hosts for adult ticks.
Reduce the risk of tick bites by wearing long pants with covered ankles when walking in areas with a lot of ticks. Using repellents containing DEET or Icaridin on clothes will also reduce the risk of tick bites. Ticks are easier to spot on light clothes.
Walk on paths in tick areas instead of high grass, heath and scrub.
Vets can prescribe agents against ticks for use on cats and dogs.
When you come home after walking in tick areas, check yourself, children, dogs and cats thoroughly. Ticks like to seek out thin-skinned places such as behind the knee, groin, armpits and behind the ears, but can be found elsewhere on the body.
