I know you have lots of pets..
Put all feed up at night
store in metal trash cans
and buy the big rat traps not the small ones those are for mice
Trap at night
and use peanutbutter
set them along the wall rats like to stay close to the wall
Clear all plants and shrubs away from house or barn
We had rats move from the neighbors to our house when they cleared out some shrubs what a nightmare..We tried those sticky ones and they were gone in the morning
Good luck hope this helps some...
