Our certified installers place the TICK BOX ® units at measured distances around the property. A protective perimeter is formed as the units are strategically installed out of view and secured to the ground. This system is installed in 2 phases, the first in spring for the nymph stage ticks and the second in summer for the larvae stage. At mid-season nymph stage units are replaced with larvae units, all units are removed by the installer at the end of the season.
