How do you guys get rid of stray dogs without guns?[Cheap poisons that work]Miscellaneous(self.Dogfree)

I am from India and the local municipal corporation won't do anything about the ever increasing dog population in my neighborhood since they didn't bite anyone yet and no one else is complaining about them. There are people you can hire who takes care of strays illegally for a certain sum of money. Since I am a student, I don't have the money to pay them to do the job. The thing is if I try to kill or harm a dog in the open people bats an eye. They won't do anything but there are a lot of instances where dog nutters not understanding that they live in a poor country where everything isn't ideal jump on the bandwagon that killing dogs yourself is bad and they try to impose morals that might work in western countries on others. They literally start a protest for dogs and make the lives of people who kill dogs, hell.

What I want to do is kill dogs secretly. I am thinking about poisoning. I tried lacing food with human medicines that harms dogs but it didn't work(it only worked once). What are certain poisons that are cheap and will work? I read that kerosine is poisonous to dogs but if I spray kerosine on their noses will it do the job? I read that antifreeze works too. Do I need to lace it with something or will these fuckers eat it directly? Will the cheap antifreeze work?
