Are a girl's parents legally allowed to visit their daughter post marriage, against the girl's will?

Sir/Ma'am, I am a 19+ year old girl as on Aug'19 and got married after turning 18 on May'18( love marriage). However, my parents did not and have still not accepted our marriage by heart, but show that they have, to rest of the world. After a long series of debate and mean actions being taken by them post marriage, I got totally fed up and decided to get completely aloof from them. However, after an year long they have suddenly started haunting our place, demanding a solution and justice. They keep coming, remain to stand outside the house creating a scene and when brought inside, shout on top of their voice, accuse my husband of trapping me in, scream and compell us to loose our temper at one moment, and just on the other, put a smile and demand a solution. Even after several requests and pleas to leave us alone and let us be, they are just not ready to so. They keep coming in intervals creating a big fuss and making me more and more mad. It's unbearable now. I really need an advise on how to stop them, without bringing any single person at home. Please help!!!
