The PreVent Auto Dispenser is an excellent solution to cluster flies in the loft. It contains a natural pyrethrum based insecticide which it releases on a timed basis. The dispenser can be set to spray at 7.5, 15 and 30 minute intervals. If left in operation for 24 hours, seven days a week, the approximate life of the aerosol will vary thus: 7.5 mins - 15 days; 15 mins - 30 days; 30 mins - 60 days. Each 250ml aerosol of Prevent Auto contains 3000 metered sprays.
Please note: price is for PreVent auto dispenser and one Prevent insecticide aerosol. Replacement aerosols can be bought separately. Requires 2x C Batteries (not supplied)
First ensure that you do not have bats roosting in your loft as the product is toxic to bats. Then stand the unit with its timer on in your loft or problem area and the dispenser will release a puff of pyrethrum into the air eliminating cluster flies as they come into hibernation. The time-release spray is particularly useful as sprays are ineffective against cluster flies when they are in hiding. Use March-June and August-December for maximum effect.
Whilst the Prevent Aerosol is particularly effective against cluster flies, it can also be used against many other crawling and flying insects, in particular woodlice, booklice and silverfish, bedbugs, cockroaches and fleas. As it contains natural pyrethrum it is safe to use indoors including in food storage areas.
Contains 1.0% w/w pyrethrins synergised by piperonyl butoxide. Made from natural ingredients.
