Catchmaster 100i Insect Monitors use a food grade molasses that is already applied to the boards to attract insects. Equipped with an adhesive backing you can place the Catchmaster 100i Insect Monitors anywhere and in any position so you can make sure that your monitors are where insects are likely to pass. Each board consists of three monitors that can be torn off using the perforated lines, or you can use the entire board as a large trap. The adhesive backing on the Catchmaster 100i Insect Monitors can last an entire year under normal circumstances giving you peace of mind that your monitor will be where you put it for a long time.
