Wife heard scratching and chewing above her bedroom in detached house. K5 came and looked around on the roof finding no entrances. Since scratching only at night, K5 suggested it was mice. Indeed the fellow found mouse poop in the garage. Asked if I wanted to lay some traps and bait first since trying make a house mouse-proof is a quite expensive.
I opted to give it a shot and indeed, caught one mouse in the spot he identified. Have not captured any other, nor in the attic. My cats found 2 tiny baby mice in the furnace room. Will need to look for other openings so my cats don't become too entertained by mice.
K5 showed up on time and was easy to work with. His consulting fee was reasonable to me.
