Just outside downtown Prairie Hill | I haven't done the math...but spraying isn't a one time deal either. My brother-in-law uses these around a rather large horse barn (20 ish) likes what they do. You receive the larve on schedule and just sprinkle them out. Like I said, not sure whether we will do this, but they are a workable aid for fly control. Company I talked to also suggested hanging bait traps. |
