Naprovit PRO Plus
All-natural formula Naprovit PRO Plus controls mosquitoes, spiders, wasps, hornets, midges (No-see-ums), gnats, and many other types of small flying insects. It is non-toxic and poses no adverse risks to humans, pets, plants or the environment. Naprovit PRO Plus is one of the most popular choices for automatic misting systems when more toxic alternatives cannot be used, including around sensitive plants and aquatic areas (such as over lakes for Boat Dock Spider Control). It can be used indoors and outdoors, as a ULV, space spray or contact spray around fruit and vegetable storage areas; stored food areas; on peanuts, nuts, beans, and seeds in bulk, bags or other packaging; in federally inspected meat and poultry plants; on stored grains; on animals; and anywhere treatment of outdoor annoyance pests is necessary. Additionally, Naprovit PRO Plus does not contribute to insecticide tolerance or resistance in insects.
It important to note that since Naprovit is a soap based concentrate, you cannot use an agitator as it will cause excessive foaming.
