Any question answered...

thanks for all the mouse advice, after catching 2 big mice yesterday, havent heard or seen a peep our of any of them,

even left a piece of cheese out to see if they would go for it but its still there!

I also bought some body filler back from work and i'm gonna go block up the gaps - see what the landlord makes of that!

surely if you live in a rented house/flat, then this is the landlord's responsibility? ask them to call in proper pest removal types, and then you won't have to worry about whole nests of the little buggers flourishing in some forgotten corner.
