Visitor's in the house...

Was lying in bed saturday night, and heard scratching in the ceiling above me.... :( Could not sleep for the night, was home alone too had to switch bedrooms to get away from the noise!!! Following morning i put poision in the attic space and a few hours later it was all gone, put down some more and set a few traps nothing got yet, but had a silent scratch free night last night. Just hoping its mice and not the bigger furry variety, must put some poision down around outside too...
