The unique sugar based fly bait that lures house flies away from nuisance areas and kills them fast - in less than one minute after contact for up to 4 weeks. When a protein source is added to the sugar based QuickBayt it then becomes equally effective against bush flies. QuickBayt can be scattered, painted onto fly resting surfaces or used in FlySentry bait stations. It's a non-scheduled poison with added Bitrex (a foul tasting animal deterrent) so it's safer around families and pets.
