help with wild snakes

My girlfriend woke up this a.m. to my daughter yelling about a snake in the house, turns out that it is a venomous snake.. now yhey are afraid To stay in the house. What is some things that can be put outside around the house for them to have piece of mind? That wont hurt our pet snakes.

I believe the snake away product should work by putting it around the edge of the land ( border like fence ) and will help keep them away, I am told it works great but then gain I don't use it personally.
I find a way to make a snake attracting version to put to draw snakes to me lol.

I tried to tell them that there prob. Wouldn't be another one in the house this year..but since I am over the road driving trucks and not there she said she didn't want to chance it. Someone else told her to put snake away around the house also. I just don't want the fumes or
Smell of it or anything else she could use end up harming our pets.
