Product information

Brand: Pro Washroom
  • Cluster Flies are an annual problem for many properties and often appear in awkward, hard to reach areas such as garages, lofts, and attics.
  • Prevent Auto is designed for exactly these areas, fitting into an automatic air freshener dispenser that allows you to regularly treat an area with insecticide 
  • Ideal for areas where smoke bombs and sprays aren't convenient or applicable such as unoccupied spaces, roof voids or the back of garages.
  • Simply fit the dispenser to a wall with a Prevent Auto tin inside, and program the dispenser to spray at intervals of either every 5, 10, 15 or 20 minutes, and either 24 hours a day, or only during daylight or night hours.
  • This pack provides 1 dispenser with 3 Prevent Auto Tins.

More Information on Prevent Auto Aerosol:

  • Prevent Auto insecticide spray provides super fast-acting insect knockdown.
  • Each spray dispenses 1ml of PreVent Auto insecticide spray, creating an environment that quickly knocks-down and kills flying and crawling insects.
  • The formulation and low dose dispensing means that it is effective in controlling insects while being safe to humans and other mammals that may be present.
  • One PreVent Auto aerosol in a dispenser correctly sited will keep up to 170 cubic metres of space free of a wide range of insects.
  •  Prevent Auto is made from pyrethrum, a natural insect-killing ingredient that comes from the chrysanthemum plant.  
  • Approved for use in food hygiene areas HSE8504 
  • Dispenser takes 2 x 1.5V D batteries (not supplied).
