June 2011 I bought the ticks roles for the first time and gebrauche now in the 3rd season. Our garden is approximately 1000m2 large, adjacent to a wooded area. It (was) therefore immense problems with ticks. I am very happy with the product and the intelligent method. What I have indeed noticed is that has greatly reduced the high number of ticks. As Micro biologist I am glad that there are ticks with rollers a gentle alternative for the environment and surroundings. In my opinion, the application is much more direct and more environmentally friendly than the use of biocides sprays.
