This is very difficult, if not impossible to achieve. As ticks are very susceptible to desiccation, removing trees and shrubs will increase the amount of light to the ground, thereby decreasing the humidity levels and making conditions unfavourable for tick survival. Often this involves considerable environmental destruction and is not advisable. The presence of ticks in an area indicates that there are native animal hosts present (usually bandicoots) and this suggests that the environment is natural and healthy. If ticks are present, then it is best to undertake tick avoidance measures.   _{Your Comment}
