Susan from Sarasota, Fl, United States writes,
What is best to use in open, concrete block barn with horses to control flying insects (flies, mosquitoes)...
Barn is concrete block but very open in design. Could spray outside,inside stall walls & tops of walls and underside of roof/overhang. Would like to have residual effect, not just knockdown. Can remove horses until it dries, but horses definitely rub and touch walls. Thanks.
PermaCap CS is labeled for flies and will provide a lasting residual but a slower kill. We would also recommend the Maxforce Fly Spot Bait that kills flies in a minute or less in most cases. Maxforce Fly Spot Bait is labeled for use indoors and outdoors in commercial settings and outdoors for residential settings. Just one small spot of bait will last up to 6 weeks to provide indoors and 30 days outdoor control of pesky flies.
