What entry do they come in I have them start outside on the woods and then they eventually come inside my home and not sure why it what entrance is letting them in . I just moved 3 months ago from a home 30 miles away because it got so bad and it is already happening again and I lived in my old house 9 years don't want the activity to get as bad and it's already getting very heavy in my new home. Is through air vents ,cracks,or the door?

First, explain what kind of activity you are noticing. Entities don't need normal egress, like doors, windows open, etc.

The front door! I kid...

Ghosts are spirit... they don't require the physical to function.
Superstitions like putting salt on a window to keep a spirit out fail because spirits don't need a window to get in. In a general sense, spirits enter a home (or a person) when they have a SPIRITUAL right to be there... not a physical one.

I'm with Tickle and am curious why you think you have ghosts coming in to your home to begin with?

The front door! I kid...

I was going to say that...then I was going to add that they need your permission and then I was going to do the whole vampire thing and....whatever, glad you said it first because you saved me!

But, I am adding here because this question did intrigue me in that I am also wondering what is happening that is causing the OP to think they are having spirits come into their house.

It was too hard to resist ;)

When people play around with ouija boards and so sayonces and with craft. I believe yet I don't know for sure if an evil spirit drives someone to kill someone else and then themselves the spirit that possessed that person could linger after their death.

Katy, it is for sure not a good idea to play with a ouija board, or try to séances. Both can invite not so pleasant entities into your personal space. However, only in stories do they entice people to kill and then stick around to create more damage.

They can in from their own area, they do not need doors or windows.

Next they do not possess you to kill people, ( watching too many movies) but tell us what is happening
