Too Many Flies and Mosquitoes on the Pig Farm? Practical Control Measures to Solve It

Practical Measures to Solve Flies and Mosquitoes on Pig Farms
Although mosquitoes and flies do not fall within the scope of parasitic diseases, I believe the harm they cause is more serious than any parasitic disease, so I also treat them as parasites; because mosquitoes are the transmission route for Japanese encephalitis and eperythrozoonosis, while flies are the main transmission route for digestive tract diseases. If mosquitoes and flies are not eliminated, disease will never stop.
But it is very difficult to have a pig farm free of flies and mosquitoes, because as long as the temperature is suitable, garbage, manure and spilled feed are all places where flies can survive; and wherever there is water there are mosquitoes - rain, wastewater and so on are all places where mosquitoes survive and breed. But as long as you put your mind to it, these two pests can be eliminated. Below are some specific methods for solving flies and mosquitoes on pig farms, for reference:
I. Fly control
There are many ways to deal with flies. The commonly used method is to spray fly-repellent or fly-killing drugs inside the barn, but these methods cannot fundamentally solve the fly problem. The solutions below mainly focus on eliminating the places where flies survive and breed - this is the way to eradicate flies, for reference:
1. Add drugs to the feed: Cyromazine is a highly effective insect growth regulator. It has a killing effect on the larvae of Diptera insects, and in particular has a good inhibitory and killing effect on several common fly larvae that breed in manure (that is, maggots). Adding it to the feed can eliminate flies before they become adults. This method has produced good results on quite a few pig farms.
2. Eliminate fly breeding sites: Another way to thoroughly solve the fly problem also starts from the eggs. The method is to regularly cover the pig manure produced each day with plastic sheeting, relying on the seal to suffocate the fly eggs inside the plastic. You do not need to cover it every day, because it takes a certain amount of time for flies to develop from eggs into adults; changing the sheeting once every three days is enough to kill all the eggs. Note that when covering with plastic sheeting, it must be sealed tightly. If the plastic has holes, they need to be plugged tightly with soil or something else; there must be no place where air can leak.
This method is a supplement to the first one, because piglet feed on pig farms is mostly complete feed, and drugs cannot be added to it; and piglet feed is also the type of feed that is wasted most seriously. Piglet manure and spilled feed are still breeding sites for flies.
3. Many pig farms still have quite a few flies in the barns after adopting the above methods. The reason is often inattention to hygiene inside the barn, especially feed that nursing sows and piglets in the farrowing house drop on the floor and that is not cleaned up for a long time, which becomes a place where flies breed. Regularly checking the barns for spilled feed and dealing with it promptly also reduces the number of flies to a certain extent.
If the above three methods are used in combination, solving the fly problem is a very simple matter.
II. Mosquito control
1. Keep the enemy a thousand miles away: A large mosquito net means using window screening to cover the entire pig barn. This method is relatively practical on small pig farms. We have tested it: if window screening is nailed over the windows, it can effectively block mosquitoes from entering, but because the mesh is fairly dense, it seriously affects ventilation inside and outside the barn. Especially in the high-temperature season in summer, the temperature inside the barn will be 2-3°C higher than when windows are open for ventilation. While solving the mosquito problem, it causes the barn temperature to be too high. In particular, prolonged high temperatures in the farrowing house reduce sow feed intake, and high temperatures in the gestation house also increase the number of stillbirths. With a large mosquito net, the entire pig barn is wrapped up, the ventilation range inside and outside is increased, and the ventilation effect is much better. If mechanical ventilation equipment is installed inside the barn, this measure becomes much more complete.
2. Remove the firewood from under the cauldron: Applying medicine to standing water is to control the places where mosquito eggs are produced, so that mosquitoes are killed before they become adults. This method is relatively practical in the water-scarce areas of the north. As long as insecticide is placed once a week in places with standing water, such as drainage ditches and accumulated rainwater, most mosquito eggs will be killed. This can greatly reduce the number of mosquitoes inside the pig barns.
3. Build high walls: In the water-rich areas of the south, many mosquitoes fly in from outside the farm. If a one-meter-high window screen is installed above the pig farm wall, the number of mosquitoes flying in can be greatly reduced. Together with mosquito control measures inside the farm, this is also helpful for preventing the harm caused by mosquitoes. (If it can be designed to be taken down during the day and hung up at night, the effect is even better: during the day it does not affect ventilation, and at night when large amounts of ventilation are not needed, hanging it up can block mosquitoes.)
4. Set up a minefield: Some pig farms use mosquito coils to repel mosquitoes, which is also worth considering. Because the smell of mosquito coils keeps mosquitoes from approaching, lighting mosquito coils inside the pig barn can keep mosquitoes from entering the barn. Compared with the harm mosquitoes do to pigs, the investment in mosquito coils is still relatively much smaller.
5. Fortify the defenses and clear the field: Weeds are often the places where mosquitoes rest during the day. If there are no weeds in the pig farm, mosquitoes have nowhere to hide. Eliminating weeds will leave mosquitoes with nowhere to hide, and it is also a way to reduce mosquitoes.
6. Lure the enemy in deep: Setting up mosquito-killing lamps inside and outside the pig barns can attract mosquitoes in and kill them with drugs.
The above methods are some feasible measures actually used on pig farms. I hope pig farms can flexibly choose according to their own actual conditions

Thanks to the original poster. This summer I also suffered greatly from mosquitoes and flies and used some methods, but the results were not very good. I have also used some of the ones mentioned above by the original poster. Personally, I think a drug called "Jiakang" works well. I do not remember which manufacturer it is from now.
