On a recommendation from a friend, I purchased two cans of Country Vet Insect Control in order to combat the flies that gather in our work warehouse during the summer months. At the end of the day, on my way out, I walked through and sprayed the walls and other spots where flies normally land. The next morning, and for two days after, there were no flies, other than a bunch of dead ones on the ground. This stuff works pretty good, and I would recommend it for large areas where flies are a problem.

Prefer the mosquito and fly formula. Use it in my tack room/milk room. It is quite efficient. I no longer need flystips in there. Even if i work with the doors open while coming and going when i come back next time, the room is bug free. I have also thoughly reviewed the uses and areas where it is safe. This is a milk handly area and i am exposed to the fumes and it seems i am safe on both counts.
