Indeed is amazing what small holes they can get in
Few years back I kept seeing mouse droppings under the sink in the cupboard and couldn’t work how they were getting in
Got fed up so I removed the waste pipe and found they were living in the cavity wall insulation as they had made a hole for nesting
After many months found they were coming from my previous neighbours next door who just chucked food waste out in their garden
The mice went all the way through the cavity from there house and onto my sink cupboard , sealed around the pipe and after a few weeks they disappeared and thought that was the end of it , but no there’s more
Would often leave my kitchen door open so my dog candy could go in and out at her leisure , one evening whilst watching TV I saw them out the corner of my eye coming across the front room floor and onto candy’s food bowl that contained her dog biscuits
Watched them in disbelief for around 5 x minutes watching them go back and forth
Found some excellent rat traps from the states which were very effective along with poison , placed it inside some of the rat boxes so that candy couldn’t get hold of the poison
Really didn’t like using the poison but had to get rid of them and looking out the back bedroom window the rats had migrated to under next doors wooden deck seeing they kept throwing there food out there door without placing it on a bin
Spoke to them about the rats and was very polite and asked if they would be so kind to put there black bags in the bins
In the end I caught around 10 x rats as they had burrowed under my fence and under the corner of my concrete patio slab
Da, sorry as I’m waffling away
