Pest Management Bulletin 473 Baits Fly resistance to certain chemical sprays means more reliance on baits or space sprays of other chemical classes. Although fresh bait will help control flies, results may be poor if fly breeding is excessive. Use baits liberally for best control. Apply a minimum of 4 ounces of bait per 1,000 square feet of floor area. Increase amounts when flies are breeding prolifically.
Baits are most effective when used in conjunction with other control measures.
However, do not apply baits where livestock, poultry , dogs, cats, wildlife, birds or children may eat them. Do not contaminate feed or water. Hang jugs from ceiling by wire. Pour out dead flies and replace bait weekly.
