Do put mosquito net around the shed (as against using a shadenet) if possible. In my village farmers also make use of neem and honge leaves smoke by putting them into fire/coal and allowing the smoke to pass over area where cows are tied - generally in outdoor.
Hi
I am not facing any mosquito problem, however during day time we have fly problem.
To tackle, we are spraying the cow with a chemical called Cypermethrin, which is available in any veterniary drug store. There are other solutions like spraying neem oil, but the best result we have got is with the chemical one, and till date no side effects on the cow.
The effect of the chemical lasts for some 6-7 days. Since we wash our cows weekly, we spray after they are washed.
Citronella oil is an excellent measure to keep mosquitoes under check.The ‘all out’ like refills are available with CIMAP which canbe fitted near all milching cattle.Till the smoke of citronella exists no mosquito will come near by.Also you can get net type system fitted in dairy which will obstruct mosquitoes menace & their movements.
