year an early start gives the beneficial populations time to increase to larger numbers in the manure and will result in fewer fly problems for the rest of the summer counting the number of flies caught in jug traps with bait in them or on fly tapes is an excellent way to monitor changes in fly populations baited jug traps are easily made by hanging a gallon milk jug that has four 2 to 2½ inch holes in the top half of the jug with a wire one ounce of bait is placed in the bottom of each trap baits containing the fly pheromone muscalure muscamone® z-9-tricosene are the most effective at attracting flies golden malrin® blue streak® stimukil® apache® and flytek® are some brands that contain 1 methomyl a carbamate flies eat the bait and quickly die these traps should be hung about one foot below beams near areas where flies are often seen resting or where fly specks are concentrated if you empty the trap weekly and estimate and record the volume of dead flies it is one way to assess how the program is working from the breeding sites protects naturally occurring predators that contribute to the success of the overall program results of over 95 control are achievable by trapping and baiting the adult flies and releasing parasites into fly breeding sites when flies are present in humid areas and wet manure accumulations especially where manure is washed into pits it takes parasite releases and bait stations to give excellent fly management when you start releasing parasites set up at least one bait trap inside each barn or shady area where you see high numbers of adult flies as indicated by fly specking ­ see below trapping along with parasite releases should continue until flies are gone z-9 sex pads lure flies to traps special traps for biting flies fly parasites do not attack many biting flies see catalog for sticky traps horse pal and the nzi trap simulate the side of a cow and physically trap the fly see www.rinconvitova.com for current links to information about traps for biting flies 3 control of fly breeding sites cone and jug style fly traps sagebrush traps can be baited with rescue® or final flight® fly bait containing muscalure and feeding attractants no pesticide and used in sensitive environments and on organic farms good sanitation practices that eliminate conditions favorable to fly breeding are critical to limit fly problems frequent manure removal reduces the breeding sites keep areas around watering and feed troughs clean and dry wet feed and wet manure are good for growing maggots fly larvae maintain ventilation to dry the manure and eliminate wet areas wherever possible large amounts of manure can be managed in a pond or storage where non-aerobic digestion is accomplished or by aerobic composting systems unprocessed manure can be piled and covered or watered ­ depending on climate ­ to speed decomposition this reduces the surface area and heat builds up to reduce fly breeding dry manure will not breed flies the interface between wet moisture content of 50 to 80 and dry manure is where fly breeding occurs this is also where the fly parasites work best sagebrush trap s3 most flies are resistant to all contact pesticides however when flies eat these toxins in a bait they will die begin applying registered fly baits whenever and wherever adult flies tend to accumulate releasing more parasites suppresses the number of fly pupae and increases the number of parasites keeping pesticides larvacides away sludge pits can be improved by adding aeration anaerobic digestion attracts flies and produce airborne chemicals that are not good for the health of animals and people we can provide references for aeration equipment we also sell ophyra a predatory fly that lives in sludge pits and attacks fly larvae www.rinconvitova.com page rincon-vitova insectaries inc 2005 catalog of beneficials for fly control 800-248-2847 bugs 9
