Buy some Prozap LD-44Z to go with it. It’s intended for stables and such, but works just fine for non-farm/ranch applications. Stuff is amazing for minimizing the number of flies that get in your house. We live in the country and flies like to gather around our doors as it is shaded. Spraying the outdoor door frames and nearby walls really cuts down on the number of flies we get in the house. Don’t spray it on the glass as it leaves a film.
