The Night Stick was developed to address the increasing worldwide problem of bed bug infestation. It has become the most cost-effective method on the market for early detection against this growing epidemic. The Night Stick allows you to sleep comfortably knowing that bed bugs will be detected and trapped before reaching your bed. Early detection is critical in identifying bed bug activity and essential to preventing a possible infestation before it starts. The Night Stick package includes (4) inserts that install easily and discreetly in the 4 corners on all bed styles. The Night Stick was designed to do its best at providing multiple harborage sites. The top edge, as well as the grooved surface is designed as harborage points without the use of glue. Also, scattered among the grooved surface is a maze of glue filled holes, providing an increased opportunity to capture the bed bug as it tries to navigate throughout the maze of sticky, perforated craters. The Night Stick’s specialized non-toxic, pesticide free formula and design is intended to lure bedbugs & other insects into the trap for detection! No returns on opened, used or damaged products.
