What will the installation of the pheromone look like?

The MCH pheromone is contained within a capsule that slowly releases the chemical over a period of three months (April – June). Each capsule is housed within a plastic strip that is stapled to the tree at a height of 6-8 feet, usually on the north side of the tree. 

In the forest and picnic area, tabs will be placed on a rough grid, so they will appear scattered around. In the Rhododendron Garden and Native Plant Garden, tabs will be placed at borders or on individual, high value trees that may be quite close to one another.
