The flies will not live or die in the Florida Fly Baiter. They will approach the Florida Fly Baiter, consume or touch the bait you have applied to the product and fly off. The flies will typically die pretty quickly after being in contact with the bait (usually within 1-30 minutes) depednign on which bait you use. We recommend using the
Maxforce Spot Fly Bait for use with this system.
