The reason behind rating 5 star to this HIT SPRAY is that it has been our best friend specially in rainy season because in rainy season various kind of pests and rodents try to enter the house espcially when the light is switched ON.This Hit spray is not only beneficial to kill coacroaches but also kill other insects and pests such as centipedes, etc.And the most good thing as that now a days it is coming in very sweet fragrance that does not make it bad to smell.It is a best insecticide for coackroaches because they can contaminate our food in night but spraying this HIT SPRAY near dishwashing sink and other prone areas make us safe.
