reminds me back in 2008 when we bought Brand New Honda Civic Oriel, the very next day we had a mouse in our dashboard :@
i sprayed, i deployed traps, i parked my car in the sun.
2 days after thought everythings fine and one day my father was driving me to school and i opened the glove box, it jumped on my lap and then ran away to the back seat of the car and hid underneath.
we took the car to Honda Body Shop in I-9 and they dissemble the dashboard, and took out the seats.
they sprayed mortien spray so much that i was standing around 10 feet away and i couldnt breath.
after around 5 minutes, say the mouse coming out of the car and ran away.
they assembled the car back in around next 20 minutes and we were good to go.
only that the smell of mortien was in the car for the next 1 week. but 3 airfreshners did their job and it was all cool by then
