Mice in the basement
Looking for some advice regarding mice in the basement..
So my cousin was staying in my basement, and that's when we started discovering mice. We assumed it was because my cousin was eating in the basement which attracted the mice. We used mouse traps and the mice glue traps and were able to catch 7 mice. My cousin went on a long trip and hasnt been back for around 3 months. We left all the traps in the basement (with food on it) and didnt catch a single mouse for 3 months. Just last week we suddenly caught 1 and today another one. So basically there was a period of around 3 months where we had none. We assume after my cousin left (no smell of food) the mice stopped coming.
Now we are thinking , are the mice coming in the house some how? i mean we left the traps for 3 months with no results and suddenly they are back... Our basement is finished and we have looked around the house and haven't discovered any holes for the mice to enter... Is it possible they enter through vents? or something...
Any ideas/suggestions ?
