I cant get rid of mice in my appartement (sims 4 city living)

Moved to Sims 4 forum.

@ugly_sims  I'm not sure what you've tried so far; it would help if you let us know exactly what you've done that hasn't worked.  In the meantime, here's a thread with a couple of useful links:

Put a solid object in front of the mouse hole -- like a bookcase.

Don't know if it actually works, but I've had a sim in an apartment for nearly 40 days, and no mice so far!

@ugly_sims 

I know there is one apartment in the Arts District that has the mouse hole object that generates the mice.  It's a one bedroom and the whole apartment is sort of run down.  I believe there is another one in one of the other zones that's sort of like that too but can't recall which one it is atm.  In addition to the mouse holes, those apartments also have the exposed electric boxes that short out from time to time and they also have roaches.  Most of the other apartments in San Myshuno don't have any of those objects.  So the simplest fix for your issue is to move your sims to another apartment that doesn't have those things and you'll have no mice or roaches and no electrical outages either.

Hope this helps.
