In winter, you can stay warm without being sweaty and uncomfortable. 4 No Mosquitoes or Ticks : This is a godsend. If it’s above freezing and there’s no snow, ticks can be out but at very reduced numbers. 5 Identification of Targets: As long as you can identify the invasive by the bark and structure of the plant, identification is much easier. Without leaves blocking your view, you can see so much better.
