I've noticed something as well even before you arrival. So I've put rat poison in each of the rooms on each floor, including the bathrooms.
In the kitchen downstairs I've put normal cage rat trap, also ine sticky trap .
Unfortunately, due to the hot summer , my neighbors also alerted me that there are rats around which is unusual.
The other thing is that the houses got double brick walls with a gap between, and rats / mice are using it.
So it's a matter of time when it hits the traps or the poison.
I am not aware of any other way to catch a rat/ mouse. I cough two on sticky trap earlier in my back yard and have eliminated them.
If you know any other method or any idea how to fight them, I'm all ears, and I'll highly appreciate it.
Nobody likes rats/ mice but they're still around. Seem some managed to develop intelligence how to avoid poison/ traps. Otherwise i cannot explain as I've put all in place 2 days before your arrival.
And yes, after you've left I've found droppings in the bathroom too. And the poison in the corner of it and the two bedrooms untouched.
Many thanks Ivaylo
