The Cluster Fly Prevent Dispenser is one of the leading solutions to dealing with cluster fly infestations in your home or building.

This battery operated timed dispenser can be set to spray at 7.5min, 15min and 30min intervals where it releases a powerful insecticide for killing cluster flies with ease.

Cluster flies come and go in the evenings and can be hard to target if they are congregating in lofts and attics. This dispenser can be placed in the target area for constant control 24 hours a day.

Please note: price is for Prevent auto LED dispenser, Prevent insecticide aerosol and 2 x C Batteries . Replacement aerosols can be purchased separately.

Contains Pyrethrins.

How to use

  • When you receive your dispenser it will come installed with batteries and aerosol ready to go.
  • Upon inspection you will notice the dispenser can be set to spray at 7.5min, 15min and 30min intervals (we recommend initially setting to 15min for 30 days of aerosol life)
  • Once your dispenser is ready to go place it in the area where the cluster flies are active.
  • Turn the dispenser on by using the switch on the side.
  • Upon every interval the dispenser will release a puff of pyrethrum into the air eliminating cluster flies as they become active.
  • Pyrethrum is safe to use indoors including in food storage areas.
