Hi Sandeep, I can understand the nuisance of Mosquitos in Dairy Farm and even at Goat/Sheep Farms, due to which, the animals does not sleep properly and consequently fell sick, the yield of milk goes low, the growth of animal deteriorates day by day.
Here is a natural phenomena for preparation of Mosquitos pesticides. Follow the steps below for preparation:
1. Collect the urine from Cows every day and store it in a pot of 50 Ltrs capacity.
2. After collecting 25 Ltrs of Cow Urine (50% of pot capacity), mix 10 kgs of Dry Neem Seeds Powder, 5 kgs of Tulasi leaves with collected cow urine and cover the pot with airtight and store this preparation for 15 days.
3.After 15 days, remove the cover and mix the preparation with cowshit and make round pellets and dry it on a natural stone slop under the hot sun rays. After drying the the pellets, store them under shelter at dry place.
4. Put a fire in a wide neck Natural Pot and melt 2-3 pellets everyday evening between 5.30 PM to 7.30 PM. Allow the smoke pass through the Anilmal Shed for 2 hours. All mosquitoes will fly away from the Shed will never come to that shed entire night.
Try this and let me know your feed back so that it will be helpful to others.
Best of Luck.
