Rat in the backgarden 🤮🤮🤮

I saw a rat in my back garden. 🤮🤮 we had pest control out in January as we could hear something in the loft and pest control came out and put something down to stop them and it worked, this one isn’t in the house just seen it around the back garden I banged on the door and it scurried off .. do I need to get them back out again?? 😫 haven’t heard anything in the house. Also they never got into the house the last time they used to just come through the loft (my neighbour actually had one in the house around the time we heard it!!)
