Texas is nothing a giant fire ant mound and it is an extremely frustrating and discouraging problem. I sincerely doubt the flies could die off from lack of food. The ants are active all winter long given enough cover. They nest under anything laid down for more than 10 minutes, it seems. I will look for them. Any recommendations for a source and do you happen to know the scientific name for them so that I can find them? But first a question: I use fly predators (the tiny wasps) to aid in fly control and between those and beneficial nematodes, they really make a noticeable reduction in the fly population. Would these flies also be prey for the fly predators? That would be throwing money away. the Phorid flies Genus Pseudacteon are fairly tiny flies but I don't know if they would be targets for your fly preditors or not perhaps your Land Grant college in Texas can advise, and they would be the most likely source for your phorid flies anyway. The ones in actual use are Pseudacteon tricuspis and Pseudacteon curvatus. Their life cycle is interesting. They reproduce by laying eggs in the body of the ant. The first stage of the larvae eats the heads of ants from the inside out including the brains. With severe brain damage the ant zombies wander about for about two weeks before the heads drop off. The fly pupates in the head section and the cycle starts over again
Solenopsis daguerrei a parasitic ant tries to replace the queen and control the nest other biological controls are also being tried using the flies and ants as vectors to deliver diseases to the ants. The agents include a protozoan, a fungus and a virus. Since there is some concern that these might also attack bees they may not be released for use since the bees are vital to our food chain.
I used to hold a pesticide applicator’s permit and the info on biological controls came from my brother who was a professor of Entomology in MO so I had help that wasn’t available to the average backyard poultry keeper
I'm not a tree-hugger, per se, but do try to use as many organic practices as possible for the sake of the geese and goats.The new thing is IPM intergated pest management to use the most effective control on the pest. Generally the approach pleases no one, except the people it works for! The tree huggers hate it because it sometimes calls for those toxic chemicals that they fear so much that they hate them. The 'spray them all' group hates it because it uses natural methods where they are most effective and natural methods are usually not fast enough to please them, The birds will eat Amdro (and it's not known for being pet-friendly, either), so that was never a consideration.Well think again if you can't figure out a bait station that will keep big birds out but allow tiny ants in you are hopeless! I suggest plastic soda bottles that are dry on the inside, either punch some small holes or leave the plastic caps off, the ants will find them, tie or stake them down so the geese can't play with them and are not carried to your drainage area The nematodes supposedly will kill a mound, but it requires such a high dose that it's just too expensive for the number of mounds in place -and it's best to assume it's a 15-acre mound here. I've used corn meal and cream of wheat and nothing seems to make a dent in the population. I admire your pperseverance and success.Well my place was fire ant free until i bought a load of mulch/compost from a near by city. the city was infested but I knew every place that I had used the compost and the ants first attacked me when I moved a large flower pot that covered one of their nests
Last year we had some large red ants, close to 1/2" in size, start to move in. They make big holes for the entrance to their nest (nickel to quarter sized), leave lentil-sized, gravelly residue around the entrance, but are not aggressive. They will bite if annoyed, though -Yow! We have not had a red ant population in this area of North Texas since the fire ants invaded. I am not sure what they are, but I have been told that they will run the fire ants out as they move in. I have no idea what the long-term effect will be. They seem like harvesters and do not bother the birds unless provoked. It will be a few years before the population is large enough to rid us of fire ants, but I hope it's not something that will turn out to be a worse problem. They have to be pretty hardy to stand against the fire ants and all the hybrids they've developed.
I know the DE isn't effective to kill mounds, but if it does seem to be pretty effective in deterring them from foraging or nesting under the goose nests and in keeping them out of the nests. It's at least something. I consider it nothing more than a deterrent, but it seems to be pretty effective in dry areas.
