My parent had rodents in the kitchen. The pest controller caught a rat and some mice and blocked off where he thought they were coming in from outside.
Do you think it's possible the rodents would want to be in bathroom upstairs? I've seen something that could either be dirt or droppings. I am going to get the bathroom cleaned soon. I can't figure out why rodents would be there or how they would get up there apart from using the stairs.
Any advice appreciated.
