Stray cats pooping near front door.. Tried all home remedies .. What to do?

Hi all!

I am so much frustrated by stray cats pooping near my front door of living room. My house gets so stinky that I start vomiting. I clean that area thoroughly with water and soap solution but this is daily headache since last week.

I have tried citrus peels, and other scents but they are of no use.

I hate hate hate cats because when I was a kid, a parrot use to come at my home. I use sit on my writing desk outside in aangan to do my homework in evening. Parrot started coming suddenly so I started feeding it. But then after about a month or so, when parrot came and I went inside to get some food, a cat attacked that parrot and killed it in front of my eyes.

From that day I hated cats. So I want this pooping cat out of my house asap, plz suggest something.
